KOSUN Decanter Centrifuge Efficiently Removes Undesirable Solids

A KOSUN drilling mud decanter centrifuge efficiently removes undesirable solids from drilling mud in crude oil extraction. KOSUN drilling mud decanter centrifuges are designed specifically to remove unwanted solids and fine particles from virtually all kinds of used drilling mud, including those based on water/synthetics and conventional oil-based drilling fluids. Built for heavy-duty processing, a KOSUN installation handles large quantities of solids in the feed flow, as well as being able to cope with coarse, abrasive particles. It also efficiently removes the vast majority of fine particles, down to sizes of around 5 microns. Traditional equipment is unable to deal with these particles, which have a serious impact on the quality of drilling mud because of their abrasive effect. The KOSU

Modern Application of Decanter Centrifuge

Economic justification for using decanter centrifuge s with weighted muds traditionally has been based on the savings realized by recycling the larger barite particles. However, this is not the most important benefit. When centrifuges are not used, the concentration of fines tends to be higher and the mud quality lower. This often leads to an increase in costly hole problems, which can be a much larger economic factor than the savings from the barite recovery process. In actuality, the finer barite particles are discarded with the overflow, and this can be a significant part of the total barite present. Using the quick and dirty barite recovery concept to justify centrifuge rental is a simple, though flawed, calculation that has impeded the understanding of the real benefits of using centr
