Degasser is a device used in drilling to remove gasses from drilling fluid which could otherwise form bubbles.
For small amount of entrained gas in a drilling fluid, the degasser can play a major role of removing small bubbles that a liquid film has enveloped and entrapped. In order for it to be released and break out the air and gas such as methane, H2S and CO2 from the mud to the surface, the drilling fluid must pass degassing technique and it can be accomplished by the equipment called degasser which is also a major part of a mud systems.

Vacuum Type is the most common form of degasser. It can be horizontal, vertical or round vessel. A vacuum action is created to pull in the gas cut mud.
When the liquid enters the tank it will flow and be distributed to a layer of internal baffle plates designed for the mud to flow in thin laminar film and is exposed to a vacuum that forces the gas to escape and break out of the mud.The vacuum pump moves the escaping gas from the vessel discharging it to the rig’s flare or environmental control system.

 

 

Drive Principle Removing the fine cuttings by cyclone and fine screen in the passed mud which makes through the desilter
Drive Effect Removing the solid Without the barite loss at the weighted mud
Component Column, Flange, Pipe Line etc.
