Drilling vacuum Degasser is also called mud separator or gas separator sometimes. Vacuum degasser used in the second stage of solids control equipment. The drilling mud that are separated by the first stage device — shale shaker flows into the setting compartment of the mud tank. The drilled cuttings would settle into the setting pit, and the drilling fluids would flow over and into the second compartment.

Drilling Vacuum degasser for sale by KOSUN

Vacuum degasser for sale by KOSUN is the most common form of drilling mud degasser. KOSUN is a degassing machine manufacturer in China. KOSUN Vacuum degasser 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.

For small amount of entrained gas in a drilling fluid, the vacuum 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 machine and it can be accomplished by the solid control equipment called drilling mud degasser which is also a major part of a mud solids control system.

KOSUN drilling vacuum degasser work principle

The vacuum degasser uses the suction function of the vacuum pump to form the negative pressure in the vacuum tank. Under the pressure of atmosphere, the drilling fluid enters into hollow shaft from suction line, and then to be gathered by the umbrella slices around of the hollow shaft to toss to tank skin in spurting. With the impact of vacuum and bubble centrifuge, the bubble will be broken in the drilling fluid, the gas will escape and suction out by the vacuum pump and vent to the safety zone.

The Drilling Vacuum Degasser maintenance

1. Proportion of water and gas should be noticed during adjustment so as to ensure unobstructed dewatering. There should not be waterlogging in the secondary cooler, otherwise there will be scale formation in the cooler after long-time operation, which will exert an influence on the normal operation of the vacuum degasser.

2.Timely dredging for air inlet, water outlet as well as draining line is necessary. Dramatic decline of the vacuum degree and significant deterioration of the decarburization may result from air leakage of the system. At this time, the operator should switch to the alternate tower in a timely manner and find the leaking source by means of water-filling pressure test so as to prevent the problem from further deterioration. Moreover, normal liquid level of the vacuum degasser should be maintained in order not to result in overflow phenomena.
