Vacuum degasser is an necessary degassing equipment of solid control system. Vacuum degasser can wipe off the invaded gas from drilling mud quickly, restore drilling mud proportion, keep mud viscosity performance and improve the quality of drilling fluid.

Function and location:

Vaccum Degasser is used to remove the small entrained gas bubbles left in the mud by the mud/gas separator. These units are positioned downstream from mud/gas separators, gumbo removal equipment (if utilized), shale shakers and mud conditioners (if utilized).

vacuum degasser

Unique structure:

Skid-mounting simplifies spotting and installation. The self-contained unit consists of a cylindrical vacuum tank with an internal baffle system, vacuum pump, jet nozzle and three-way float valve.

Working principle:

Gas-cut mud is drawn into the tank through a vacuum created by the discharge jet and the pump. The mud is dispersed in a thin layer over the full-length baffle and, as the entrained gas is freed, it is recovered by the vacuum pump. The gas is discharged at a safe distance from the drilling operation while the restored mud is returned to the drilling fluid system.
