  • Drilling Fluid Solids Control Equipment-KOSUN

    KOSUN is specialized in drilling fluid solids control equipment manufacturing in China since 1992. We have rich experience in solids control system design.

    Five-stage solids control equipment,including Shale Shaker,Vacuum Degasser,Desilter and Decanter Centrifuge,ensures clean mud recycling and mud can be reused.

    Five-stage solids control equipment

    SHALE SHAKER
    Shale Shaker is used as the first stage equipment for drilling fluid solids control system. It can remove 74μm or above size particle from mud.

    VACUUM DEGASSER
    Vacuum Degasser separates H2S and other gases. It is helpful for reducing cone part abrasion on desander and desilter during further handling.

    DESANDER
    KOSUN Desander is used for separating 45-74μm particle from mud.

  • KOSUN Oil Sludge Treatment System Put Into Operation In Tahe Oilfield

    Recently, KOSUN designed and produced oil sludge treatment system sent to Daqing to treat the oil sludge, the process using flotation method.

    Oil sludge treatment system features:
    Daqing oilfield sludge treatment system has the characteristics of explosion-proof, anti-seepage, anti-corrosion. The treatment system uses frist stage treatment, second stage treatment, quenching and tempering, centrifuge separation, separation of oil and water separation to ensure the smooth progress of the work site.


    Oil Sludge Treatment System

    Structure  of Oil sludge treatment system:
    Daqing oil sludge treatment system consists of frist stage treatment tank assembly, secondary tank assembly, 1 # conditioning tank assembly, 2 # conditioning tank assembly, oil and water separation tank assembly, the auxiliary pry assembly, heating pry Assembly, change, power distribution assembly eight modules and other equipment, manifold and other components.

    Effect of oil sludge treatment system:
    (1) Environmental Evaluation: oil sludge treatment is an important part of the oilfield environmental protection. Through this technology, the impact of oil and sand on the regional environment can be eliminated.
    (2) Economic Evaluation: The local environmental protection department disposes the oil sand, landfill costs about 1,000 yuan / square meter. Adopt this technology can greatly save the cost.
    (3) Technical Evaluation: From the current status of sludge sanding technology, it is difficult to meet environmental standards by a single treatment technology. Tahe oilfield chemical cleaning + air flotation separation technology to treat the oil and sand, can not only recover a large amount of oil and sediment of crude oil resources, reduce environmental pollution and improve the ecological environment, but also achieve harmless, resource-based and reduction,bringing a positive environmental benefits.

  • Working principals of Slurry Separation System

    Working principals of KD series Slurry Separation System:


    Working principals of Slurry Separation System

    1.Supply line 2.Coarse shaker 3.Collection box 4.Fine shaker 5.Main reservoir 6.Storage Tank 7.Intermediate tank 8.Desander cyclone 9.Desilter cyclone 10.Gravel pump to desander 11.Centrifugal pump to desilter 12.Solid Discharge 13. Slurry Discharge 14.Float lever control Device

    Step 1: The slurry charged with soil is conveyed to the system through the supply line (1) and let out onto a vibrating coarse shaker (2) which removes particles exceeding 5mm in size.

    Step 2: The sieved slurry drops into a collection box (3) and passes through a connecting trough into the main reservoir (5) of the desanding module from where it is pumped (10) to the two desanding cyclones (8) which separate out sand from slurry.

    Step 3: The sand pour out through the underflow outlets of the desanding cyclones (8) and drop onto a vibrating fine shaker (4) lower deck to be dewatered and removed (12) from the process.

    Step 4: The treated slurry leaving the desanding cyclones (8) through the overflow outlets pours into an intermediate tank (7) from where it passes to a storage tank (6)

    Step 5: A further refinement of the slurry can be achieved by pumping (11) already treated slurry from the storage tank (6) to the equipped desilting cyclones (9) for subsequent treatment..

    Step 6: The refined slurry leaving through the overflow outlets of desilting cyclones (9) flow back to the storage tank (6), to be conveyed (13) to the site on demand.

    Step 7: The part of the slurry leaving the desilting cyclones (9) through the underflow outlets drops onto the fine shaker (4) upper deck to be filtered out and removed from then process while the filtrate returns into the cycle.

    Step 8: A float control device (14) fitted into the main reservoir controls the fluid level in the system during the process: by opening/closing a passage between the main reservoir and the intermediate tank, the float prevents the system overflowing and pumps running dry.

  • Soil restoration obtained sustained survival momentum

    As we all know, soil pollution prevention and treatment is very urgent. Soil remediation industry has great business opportunities, at the same time, soil remediation is facing high costs, long payback period and other issues. The industry expert believes that soil remediation still need to further explore the effective business model, in order to obtain sustainable driving force.

     
    Soil restoration
     

    Soil is related to citizens' health. It is not only the material basis for the sustainable development of economy and society, but also closely related to the construction of ecological civilization. Therefore, protecting the soil environment is also an important part of promoting the construction of ecological civilization and safeguarding national ecological security.

    However, with the development of industrialization and urbanization, the contaminated soil has aroused widespread public concern. Farmland pollution is very serious, and some areas are in a period of rapid development in recent years, meanwhile, they also bring serious pollution.

    Statistics show that according to relevant departments, there are 12 million tons of soil in our country every year which are contaminated by heavy metals in the soil, causing losses of up to 20 billion yuan annually. According to statistics, the exceeding rates of arable land in our country were 19.4% respectively, and the problem of excessive heavy metal pollution was outstanding.

    From the overall situation, the state of soil environment in our country is worrying and the pollution in some areas is more serious. It has become one of the prominent shortcomings in building a well-off society in an all-round way. We must attach great importance to soil remediation.

    The state funds for soil restoration are also increasing year by year. Recently, when the MEP held a routine press conference in November, You Yanxin, head of the Planning and Finance Division of the Ministry of Environmental Protection, said that this year the special fund for environmental protection arranged by the central finance is expected to reach 49.7 billion yuan, focusing on water, air and soil Pollution prevention and treatment and rural environment remediation, ecological restoration of landscape forest and other lake grass.

    In terms of soil prevention and treatment, the Central Government allocated a special fund of 6.5 billion yuan for the prevention and treatment in soil pollution in 31 provinces to accelerated the advancement of soil Pollution Prevention and Control Zone Construction. (Editor:Kosun Lily.Wang)
