With
the improvement of environment protection awareness of the public, in the drilling
site, the advanced new technology are urgently needed in promoting the
effectiveness of drilling waste management both in domestic and international
drilling market. As
per drilling waste management, vertical centrifuge used to further separate
drilling waste and recycle oil based oil is wildly recognized in the
international oil gas exploration industry. In addition, it also plays an very
important role in reducing harmful substance in the discharged waste and make
sure that the oil on cuttings of the final disposal conform the national
regulation standard of harmful substance, the OOC (oil on cuttings) is below
5%.Vertical
Centrifuge (VC) is a machine designed to reduce the operator’s total fluids
cost and limit waste disposal volumes. This is achieved by directly recovering
the fluids from the cuttings, and by recovering any weighted mud from the
shaker screens avoiding that it can be lost due to a failure of the shaker, a
movement of the rig or the occlusion of the screen. The machine helps meet certain
fluid-on-cuttings discharge requirements that must be abided by.The
Vertical Centrifuge (VC) is a continuous screen type centrifuge with automatic
feed control designed for liquid-solid separation. The Vertical Centrifuge (VC)
is designed to recover the liquid phase of the drilling fluid from drilled
solids by exposing the latter to very high centrifugal acceleration forces
which improve fluid separation from the drill cuttings. By further clarifying
the costly liquid phase which can be returned to the active drilling mud system,
the machine helps save money on the expensive drilling fluids. Often shaker
screens get clogged and, as a result, expensive mud is lost overboard. The Vertical
Centrifuge (VC) system catches any lost mud and returns it to the active mud
system. The recovery systems work well with diesel, mineral and synthetic oil
based mud.
Vertical
Centrifuge is also referred to as VERTI-G cuttings dryer or cuttings dryer. Besides,
Hi-G Dryer, screw conveyor, decanter centrifuge, screw pump and other auxiliary
equipment can also be effectively used for drilling waste disposal.
