KOSUN LW series decanter centrifuge is used in separating suspension of solid phase with particle diameter d≥2μm for drilling mud and fluids handling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal. The centrifuge is precision –balanced for smooth operation over long periods at speeds of 0 to 3900 RPM, generating centrifugal forces up to 3000G’s.

The working environments of Decanter centrifuge:
1.Oil and Gas Drilling is the first environment for centrifuge working in the drilling industry. Decanter centrifuge spec is very strict for this environment. Normally IECEX/ATEX explosion proof standard is required for developed countries;
2.Drilling waste management industry is growing very fast and popular in Latin America and middle east. Cutting Dryer, Hi-G dryer and decanter centrifuge is the core equipment for drilling waste management system;
3.CBM/HDD drilling is a new market that require decanter centrifuge. It was seldom that clients need centrifuge to save cost but more and more clients like to working a centrifuge for better performance.
The Instruction of Coal Seam Methane:
Coal seam methane (CSM or Coal Bed Methane), coalbed gas, or coal mine methane (CMM) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, and other countries. Australia has rich deposits where it is known as coal seam gas. The term refers to methane adsorbed into the solid matrix of the coal. It is called ‘sweet gas’ because of its lack of hydrogen sulfide. The presence of this gas is well known from its occurrence in underground coal mining, where it presents a serious safety risk. Coalbed methane, often referred to as CBM, is distinct from a typical sandstone or other conventional gas reservoir, as the methane is stored within the coal by a process called adsorption. The methane is in a near-liquid state, lining the inside of pores within the coal (called the matrix). The open fractures in the coal (called the cleats) can also contain free gas or can be saturated with water. Unlike much natural gas from conventional reservoirs, coalbed methane contains very little heavier hydrocarbons such as propane or butane, and no natural gas condensate. It often contains up to a few percent carbon dioxide. Some coal seams, such as those in certain areas of the Illawarra Coal Measures in NSW, Australia, contain little methane, with the predominant coal seam gas being carbon dioxide.
Coal Bed Methan(CBM) or Coal Seam Methan(CSM) is a very important part for drilling mud cleaning system market . At the very beginning , maybe mud cleaning system is used in petroluem industry but it’s developed to other working area like HDD , Micro-tunnelling drilling , Coal bed methan & Coal seam methan , etc.
