The function and working process of KOSUN Mud Gas Separator

Mar 11, 2022

KOSUN Mud Gas Separator system consists of a cylindrical pressure vessel in a fixed vertical position. Inside is a series of specially angled baffle plates, stepped from the top to the bottom. When contaminated mud is routed into the separator, it flows downward successively over each plate. During this process, the heads of entrained gases “break out.” The released gas is then carried by the vent lines to a remote location where it can be safely flared.

The flow of liquid from the vessel can be regulated by a liquid-level-control valve or a U-tube, ensuring adequate retention time in the separator for the gas to break out. The gas delivery from the Mud Gas Separator unit to the flare line can be controlled by a back-pressure manifold (valve) in the flare line. KOSUN 
Mud Gas Separator unit is ideal to assist in controlling dangerous, near-surface expansion and accumulation of gas during a well kick.

Operating pressure within the separator is equal to the friction pressure of the free gas venting through the vent line. Fluid is maintained at a specific level (mud leg) within the separator at all times. If the friction pressure of the gas venting through the vent line exceeds the mud-leg hydrostatic pressure within the separator, a blow-through condition will result in sending a mud/gas mixture to the mud tanks. As one can readily see, the critical point for separator blow-through exists when peak gas flow rates are experienced in the separator. Peak gas flow rates should theoretically be experienced when gas initially reaches the separator.
