Vacuum Degasser is also called mud/Gas separator. Mud/gas separators (Degasser) is the first units of solids control equipment arranged to treat drilling mud. As such, they process all of the drilling mud from the flow line before the mud reaches the primary shale shakers. The units have no moving parts and rely on the density difference between the gas and the mud for removal. The process is simple, yet very effective for well drilling fluids processing system.
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 equipments (if utilized),
shale shakers and mud conditioners (if utilized), while hydrocyclone desanders and decanting centrifuges follow in the arrangement.
