Degasser
IDEC Series Vacuum Degassers that are able to service the needs of any application. It is usually installed after the shakers. Each degasser effectively and efficiently removes gases from gas-cut mud, thus ensuring that the proper mud weight is pumped downhole. In doing so, the degassers are able to aid in the prevention of potential blowouts. Unlike the traditional vacuum degasser, IDEC vacuum degasser is a self-contained unit, IDEC Vacuum Degasser is monitored by level sensor to protect over suction of the fluids. The gas-cut mud is drawn into the degasser by a vacuum created by a re- generative vacuum without needing centrifugal pump . IDEC degasser can act as a big agitator for the drilling mud, which helps the treatment for desander and desilter.

IDEC 300C centrifugal degasser is a new type degasser, specialized in processing gas cut drilling fluid. Normally it is installed after shale shaker and widely used in various solids control system, and it is very important for recovering mud weight, stabilize mud viscosity performance, reduce drilling cost. Meantime it can be used as a big power blender. Its advantages are large capacity, high rate of degassing, less area required, low energy consumption, easy operation and maintenance.

Working Principle:
Via the rotating impeller, the degasser sucks the drilling fluid into the vessel. The fluids will stay at a level higher than the gas cut drilling fluid and then a cylindrical liquid layer with inverted cone shape space in the middle will be formed. Drilling fluid is discharged from discharge port along a tangent line. With the impeller rotating, bubble breaks, gas will be extracted from liquid, and finally accumulate in the cone shape space as the lower density. Pressurizing unit(similar to exhaust fan) will suck air through the narrow channel between the air distribution disk and air separation ring into the discharge cone, and then gas manifold, braided hose and pressurized device to pressuring unit, finally discharge the gas out through pressure ing device with pressure.
