China Begins to Seriously Fight Pollution

    Chinese people have witnessed a dozen of smoggy days after stepping into a new year. Chinese government finally began to take serious measures to fight against the “pollution monster”.

In the recent years, China has been claiming more recognition and repute as an emerging economy, whose wing-footed development truly stunned its neighbors and some century-old world dominants. However, its speed is too fast to allow itself sometime for stop to have a look at how the landscape has transformed alongside.

From who-knows-what time, the air we inhale and exhale has started to contain more elements which we call dust or sand in its molecular structure. People has felt it more and more difficult to breath with such. Besides, the rivers turned foul and filthy too without much possibility to see to its bottom as before, leading to an everyday occurrence of horrible sight of dead fish bodies floating along with the dirty foams on the river surface. What is more, the installed tags in gated communities no longer produce any crystal-clean water but some yellowish mixture of liquid and sand.

Discovery of “Cancer Villages” even deepened people’s fear.

Therefore, Chinese government decided to set up a network to monitor air pollution nationwide in 17 provinces. Some experts even had suspicions that kitchen cooking should also be blamed for the emission of PM2.5 into air and called for Beijing citizens to improve on that. 

In September, Beijing unveiled a five-year air pollution control plan in which the city decided to fine any violator of the rule above 1 million yuan.

The industrial factories and some oil companies are also doing their bits. Take a solids control manufacturing company in Xi’an as an example. KOSUN Machinery Manufacturing Co,. Ltd. was established by Mr Geng Zhonghou after Premier Deng Xiaoping made the speech in his South China tour. It has launched a new set of environmental solutions by integration of experience accumulated in oil industry, several phases of grueling development and consistent research in advanced technologies. 

This solution is able to reduce the waste at its source by using solids control equipment to purify mud and separate solids at the source, dewatering the discharged waste to minimize its water content, conduct water treatment and recycling, utilizing Hi-G shale shaker and vertical cuttings dryer for further dewatering and solid-liquid separation to minimize the waste discharge, and applying solidification, biodegradation, thermal desorption and cuttings reinjection to the discharged waste for a reasonable and effective treatment on the drilling waste.

In drilling waste management, biodegradation has become one of the most favorable solutions among oil drilling companies at home and abroad due to its less expenses and the good environmental benefits it can achieve. However, different drilling environments mean applications of biodegradation vary.

Field Pic of Oil Exploration

Biological drilling waste treatment describes degradation and mineralization of pollutants in drilling waste by bacteria growth, reproduction and internal respiration introduction of degrading bacteria and nutrients with the introduction of degrading bacteria and nutrients. It also takes advantage of biological characteristics in practical operations such as, liquid/solid separation by means of bios and degradation by means of adding microbial flocculant.

Field Pic of Biodegradation

However, the practicality of biodegradation must be taken in to consideration based on the local environmental conditions before formally deciding upon this treatment approach. "Indigenous" microorganisms, nutrition factors, humidity, hydraulic detention time, PH value, dissolved oxygen should all be factored into consideration before the implementation of biodegradation.
“Indigenous” microorganisms are intrinsic microorganisms in drilling waste which do not need introduction and is comparatively economical, but is not effective in treatment. Nutrition factors play an important role in biological growth and metabolism. Therefore, drilling waste treatment needs appropriate addition of nutrition factors. Humidity is vital for biological growth and reproduction, but certainly of no significance for drilling fluids containing large amount of water. However, temperature should be kept under control. Minimized temperature is 15 degrees centigrade and the best is 30 degrees centigrade in drilling fluids treatment. Besides, for field operation of waste management, heating and insulation measures are needed for Winter and Spring and heating and cooling for Summer and Autumn. Hydraulic detention time defines how long treated wastewater stays in bioreactor. Organic pollutants in waste drilling fluids are, to a great extent, synthetic organic macromolecules which has a larger degradation rate than the other organic pollutants in wastewater, so the chosen bacteria should have better sludge loading ability. Above all, PH value and oxygen content of drilling fluids are also important factors and basic conditions for microorganisms to survive in drilling waste.
At present, the international waste treatment primarily adopts such approaches as land cultivation method, composting method, bioreactor, microbial flocculants method, anaerobic bio-treatment method, aerobic bio-treatment method, natural treatment method(oxidation pond).
Land cultivation method means to thoroughly degrade pollutants contained in drilling waste resorting to re-cultivation. It is very popular in many US and Russia drilling waste treatment sites, but it takes ages and costs a lot and is very easily affected by environment. Compositing method mainly degrades organisms by diluting drilling waste and then adding nutrients and sawdusts to attract microorganisms, which however truly is time-consuming. Bioreactor is both costly and energy-consuming since diluted and blended drilling waste and nutrient solution are put into certain tuner for adjustment of the survival factors for microorganism in order to achieve biodegradation. Microbial flocculants method makes good use of the principles of organic flocculants to solidify drilling fluids and degrade during the process. Apart from these, some drilling companies also apply anaerobic bio-treatment method, aerobic bio-treatment method, natural treatment method(oxidation pond) to improve on biodegradation and got good achievements.

Industrial Solids Waste Treatment Should Step up

      Industrial civilization boosted the rapid development of scientific technology and economy and improved people’s living standards. On the other hand, it has also been swallowing global natural resources in a stunning speed and discharging huge amount of insoluble waste, which disturbed the nature’s ecological balance and resulted in ever worse environmental crisis, exposing human survival and development to threat.
      Industrial solid waste describes the solid, semi-solid and liquid waste apart from high concentration wastewater produced in industrial production such as BF slag, steel slag, red mud, nonferrous metallic slag, fly ash, coal cinder, pyrite cinder, waste gypsum, salt sludge, etc.Along with the industrial development, industrial waste has mounted on a daily basis. Metallurgy and thermal power generation are among the largest waste-discharging industries. It is fairly difficult to manage the waste due to its huge amount, large varieties and complex composition. However, the waste can cause severe environmental pollution since it pollutes water resources, affects plant growth and endangers human fitness. Valid statistics show the total industrial waste emission in West China rose to 531.43 million t in 2007 from 243.09 million t in 2002, up average 17.4% annually. The discharging has really been intensified. Besides, since 2003 the annual emission in West China has accounted for 52% of the whole nation; though its recovery rate increased to 50.3% in 2007 from 40.3% in 2002, it still remains a lower level. It is easy to tell that the harm by China’s domestic solid waste to environment is already quite serious.
      The whole society need commit to industrial solid waste management. First of all, the governments should make continuous efforts to improve on laws and regulations to which all aspects of environmental protection can refer. Legal actions can limit some enterprises’ industrial waste emission and make them improve themselves by strengthened financial investment in waste treatment to reduce the nation’s industrial waste emission. At the same time, the country also need strengthen its investment in scientific research to facilitate the improvement of scientific and technological level and raise the level of industrial waste processing. Next, enterprises should constantly update its industrial structure and pull all energy into circulation economy development. In this way, the problems like high consumption of resources, large emission of pollutants and low level of utilization can be resolved. In the face of increasingly worse environment, we all should promote more on environmental knowledge and strengthen human environmental awareness. There is only one earth which we ought to take good care of but stain all the time since she brings us pretty rivers and mountains and clear streams. We should all do our bits to protect her.

On Sept 25th ,KOSUN 750HP, 1000HP, 1500HP, 2000HP solids control systems got the passport into EU market after officially going through all the CE conformity assessment procedures.

CE marking is mandatory within European Union market and is necessary for free marketability of the products made both by internal EU companies and foreign companies in EU market since it shows the products conform to all the basic directives subject to “The New Approach to Technical Harmonization and Standardization”. Therefore, it has been regarded as a safety mark to consumers and even a passport for manufacturers into European market. CE-marking can ensure products are sold in any EU member nation without compliance with their requirements, thus realizing free marketability of products amongst them.

EU market plays an important role in global oil equipment market. The success with CE application officially knocked the gate of EU market open for KOSUN solids control system. It also marks a landmark step on the road of making KOSUN international. As such, it paves the way into EU market for solids control system made by KOSUN

CE Vertification of Compliance

A Green Hope

Along with the refreshing wind come whiffs of sweet fragrances; chrysanthemums covered with mist represent clusters of blooms.

October sees the 64th anniversary of our mother country, for which red flags are put up flying high over our spectacular landscape and festivities put on across the nation.

Our motherland so rich in beauty has made her sons and daughters so passionate towards her. 64-year grueling development has brought the Republic up as a gigantic dragon, whose soaring raised those proud eyes towards the East. The collective“Chinese Dream” composed of hundreds of millions Chinese people’s dreams is coming true bit by bit.

“Chinese Dream”is a road to rejuvenate and a road to pursue our own individual dream.

We never stopped on the road to pursue our own dream and had been working upon it days and nights. At last, our efforts had produced golden ears out of wheats. However, when we were still immersed in the happy celebration of harvest, we suddenly noticed that our once beautiful landscape had been stained and maimed with contamination.

Our sights are veiled by heavy smog. At the early beginning of this year, smoggy weather hit a wide range of China. January saw 5 heavily smoggy days in Beijing, Tianjin and Hebei Province and only 4 sunny days. Beijing,thus, is now the new “Smoggy City” to Chinese people. While on March, 3.3 smoggy days can be counted, 1.1 more days than the average in the same period of past years, hitting the record-high of these 52 years. Suddenly, everyone panicked, at the threats caused by smoggy weather. And in many cities, the masks and eyedrops were sold out. Statistics said over 80 millions people were seriously affected this year, especially citizens from the most populated regions like, Beijing, Tianjin, Hebei Province, Pearl River Delta, Yangtse River Delta. People there seem to live in an unprecedented air pollution.

It is truly impressive to see all the faces wearing masks on the streets. It is even more impressive to discover countless cancer villages scattered across the land. In Duying Village, Shenqiu County, Henan Province, an eight-person family was all diagnosed as having fatal cancers, fishes in river deformed by pollution and an annual 2000 deaths of cancers reported. The tombs established upon lives and tears really struck the eyes and roused the minds.

In retrospect, we would find ourselves vexed by frequent headlined reports of extreme environmental pollution and accidents and touched to drop tears secretly by the tragedies resulted from pollution.

However, the dropped tears are not able to wash away the heavy dirt. We paid very heavy price for the mistakes made in the past, but we should try to avoid that in the future. Economic development is important, sustainable development is even more important. Our “Chinese Dream” needs to be an “Ecological Dream”.

Ever since 1992, KOSUN has followed China’s reform and opening-up footprints for 21 years and has grown up to be a robust young man when radical transformation is going on in China nowadays.

Chinese people has been working on their individual dreams in different all these 21 years. KOSUN has also been drawing her own dream on the blueprint and has always regarded environmental protection as the basis for corporate development whether in case of the solids control system construction or waste management system establishment.

China is still advancing and we’ve been following her footprints in the pursuit of dreams all the time. We get touched when she is in bloom and get sad when she is on the brink of environmental dangers.

Facing the future, we’d still stick to our own dreams to keep our land green and to guard our hopes.

KOSUN Jingwei Solids Control Equipment Factory Completely Upgraded and Retrofitted

READ: From 15 June to 24 July in 2013, KOSUN invested a great sum of funds into the complete upgrading and retrofitting of Jingwei Solids Control Equipment Factory Block in order to further its sophisticated management, to increase its corporate benefits, to strengthen its core competition and to build up KOSUN’ s international brand.

From 15 June to 24 July in 2013, KOSUN invested a great sum of funds into the complete upgrading and retrofitting of Jingwei Solids Control Equipment Factory Block in order to further its sophisticated management, to increase its corporate benefits, to strengthen its core competition and to build up KOSUN’ s international brand. This transforming move mainly included the betterment of workshops, staff dormitories, staff canteen and environment of the whole factory block. Now, the newly transformed workshop, the neater working environment and the complete meticulous management have been very much praised and recognized among all the staff in company.

Only when “strictness, meticulousness, honesty, perseverance” are well carried out, can the upgrading on sophisticated management be facilitated. Only when much importance is attached on details, can the management become effective. Only when all the details and sectors are carefully transformed, can the managerial benefits be maximized. Based on these three points, this retrofitting move should start from the tiny details. Now, the newly transformed factory block has taken on a new appearance, which is well-ordered and methodical. All the garbage is collected and managed segregatedly and all the safety signs posted. Inside the workshops, all the processed parts are put on the new wooden pallets sitting beside the lathes, and moreover a over-one-meter-high white drawing frame is installed next to each lath so that it will be more convenient for workers to read the drawing sheets.

At the same time, the staff dorms were also retrofitted. New bedside table, storage box and chairs are added. Considering the difficulty the worker met while washing the clothes, some washing machines are also installed. Generally speaking, everything is displayed tidily and floor swept cleanly in the transformed dorms.

What is more, staff’s board was improved, too. A list of meals is posted on the bulletin of the factory canteen, offering details of the foods provided to the workers from Mondays to Fridays. The canteen crew says to us that they will change the list every week, make sure there is meat in every meal and there are a lot of varieties. At present, though it has already early autumn, the leadership in factory still personally instructs support staff to send cooked green bean soup to workshops so that workers’ fitness is guaranteed and sunstroke prevention well done.

The strengthened sophisticated management not only completed all the corporate quality control regulations, but also encouraged the responsibility and quality awareness of all levels of staff. Ever since it establishment in 1992, KOSUN has well developed for over two decades and has been a very influential brand in Chinese solids control industry during the low-profit times, which were all closely associated with its sophisticated management implemented all these years with non-stop. In the future, KOSUN will be even stricter on quality control and ever persistent in the implementation of sophisticated management. Hopefully, all the effort would mould KOSUN a well-renowned brand in the global oil drilling solids control industry.

                                                                           Delivery Site

KOSUN has finished with all the production and assembly of equipment in early August since they settled the order and has passed the inspection from customers at the end of August.

On Oct 10th , the Logistics and Document Department took a rapid move to organize and communicate with delivery crew on loading equipment on truck after they received delivery notice. By Oct 13th , all the equipment was assembled and ready for delivery to harbour on Oct 15th . KOSUN’s rapid and safe assembly won high commendation from Russian customers.

ZJ40DB Polar Rig Low-temperature Solids Control System contains 5 mud tanks, one water tank, two diesel tanks and one MCC system. It can perform group drilling in 10 wells. NO.1 tank is set on rails with its end connected to oil cylinder which pulls NO.1 tank along the rails across wells every 5 meters for 50 meters. Besides, connecting pipes are also added between NO.1 and No.2 tank when the former travels in order to ensure the safety of system. No.1 tank features in host materials welded by Q345D low alloy steel so that it has large strength and resists low temperature well. 

What is more, this set of system is also coupled with polar heating system to include the whole system, its relative cable tanks and exposed steam pipelines under thermo shelf as drilling processes since Russia Siberia Luktoil Oilfield Block is located in polar region. It is also matched with polar steam heating system putting 2 steaming warmers atop each tank to collaborate with heating system to ensure a normal operation of the system under the terrible polar -45℃ condition in regions like Russia Siberia.

The takeover between KOSUN and Russia’s second largest drilling company--Luktoil Oil Corp. of ZJ40DB Polar Rig Low-temperature Solids Control System continued the success of the deal with Gazprom on solids control system and its successful completion and delivery. Meanwhile, the two companies have appointed KOSUN as the only solids control equipment supplier in China. This means KOSUN’s business in Russian market has  already entered the mature phase.

Techniques on Drilling Sewage Treatment

        For offshore drillings, one of the biggest drilling waste is sewage which grows out of drilling fluids, rain, water used to wash bits and cooling water. Usually, the under-treated sewage weighs 30 times the well-bore volume. Therefore, sewage minimization is a very vital part in the whole waste treatment. 

        However, as the the easiest waste resource to be reduced, water can be reduced in such ways as below:

        One-way cooling system can save water and seal it inside the system while eliminating cooling water, braking water and sealing water to achieve water recycling. It is proven that it is not pricey to recycle the water and is able to save a large amount of liquids.

        The reason that rain can be recycled is the correlation between drilling fluids and water. Rain is applicable in washing drilling equipment. The water used to wash drilling equipment can flow into water tank just like rain and should be recycled till it cannot function any more. It will be surprising to see how many times they can be reused. 

        The dirtiest water(such as, deserted drilling fluids) can be applied to wash the panel. Desander and filter can produce massive deserted drilling fluids( usually there is one portion of solid phase in 2 or 3 portions of fluid phase). They can be used to wash drilling mud tank. And shale shaker and decanter centrifuge also need washing water. Water used to clean panel do not need purifying since it is not necessary to wash away solid phase and liquid phase with clean water. It will be very difficult to separate them during treatment procedure.

         It is necessary to produce sewage. It is quite expensive to treat sewage, so vacuum device is preferable to washing water here. A gun-shaped controller with tube is a good idea. The tube falls and automatically closes the connection to disconnect the controller. Drilling operators prefer high-pressure, small-volume washer due to the less labor intensity, better washing effects and reduced sewage volume. Generally speaking, both the vacuum device and washer are put into use when treatment is not costly. However, the gun-shaped controller will offset the cost.
       Different approached can be conducted to separate and treat waste, for instance, water-based waste and oil-based waste can not blend until being managed together. During the operation, fluid from drilling mud pits should be reinjected so as to flow into spare drilling mud pits.

Realization of a “GREEN” Dream?

    On August 29th, CNN published a coverage about the famous Car City---Houston, Texas, US, which read, “Houston may be a city built on the profits of oil and gas, but it has a green dream.” 

The dream is to create a city that is "more liveable, walkable and bikeable," according Laura Spanjian, the director of sustainability for Houston since 2010, when current Mayor Annise Parker was elected.

For many years, Houston has been known as a hub producing large quantities of oil and gas. However, intensive drilling activities brought not only huge financial benefits, but also worrying environmental problems. 

As far as we all know, petroleum products help us do many things. We use them to fuel our airplanes, cars, and trucks, to heat our homes, and to make products like medicines and plastics. Though the life is made much easier, finding, producing, moving and using them can cause problems for our environment like air and water pollution. Many types of wastes are also generated by activities like drilling, production and accidental releases. All of these hazard human health and wildlife.

Therefore, laws and regulations have been enforced by governments to help reduce the hazards and new technologies developed to help improve. 

Xi’ an KOSUN Machinery Co,. Ltd(KOSUN), as the pioneer in the field of solids control in China as well as an integrated service supplier of global drilling fluid solids control and waste treatment, has always diverted energy and investment into the research and development of latest environmental solutions fit for oil drilling and exploration. 

After countless experiments and grueling struggle, KOSUN has invented a series of waste management solutions and relative solids control equipment. 

Take one as an example. KOSUN Mud/Gas Separator is an especially ideal equipment to be used when accidental release, kick or blowout is encountered. It is primarily used to separate the free gas from the drilling fluids, which may include toxic gases such as hydrogen sulfide. In this way, not only the safety of drilling is ensured, but more possible air pollution is prevented as well. 

Besides, the series of waste management solutions launched by KOSUN is different from the conventional approaches in many ways. It was born by the integration of domestic and foreign waste management experience and methods as well as the consideration of drilling waste production process. The solution upholds the waste reduction at its source. It would purify the drilling fluids and take away the solids at the source by application of solids control system. Then dewatering of discharged waste, water treatment, water recycling and purifications would work altogether to minimize water content in waste and recycle the water. Afterwards, Hi-G Dryer and Vertical Centrifuge would continue with dewatering and solid-liquid separation to minimize waste disposal. At last, the discharged waste would be reasonably and effectively treated by means of solidification, biodegradation, thermal desorption and cuttings re-injection. Thus, the goal of zero disposal is achieved and the dream of “green cities” realized.
