Vacuum degassers sometimes are essential to the solids removal process.
Shale shakers remove a good portion of the gas from a badly gas-cut mud , especially if the Yield Point is as low as 10 lbs per 100 Sq. Ft. It is generally accepted among experienced field drilling personnel that special degassing equipment is not necessary if the Yield Point of the mud is six or less , although with prevailing high figures the knowledge is academic.
Hydrocyclones are fed by centrifugal pumps. Slurry-handling centrifugal pumps for abrasive oil-field muds are not able to maintain efficiency when pumping gas-cut muds. Hydrocyclones do not function properly if pumping (feed ) head is not constant or if there is gas or air in the feed. Therefore provision for degassing should be in a stage between the sand trap and the first hydrocyclones.
Aipu solids control manufactures negative pressure (vacuum) and atmospheric degassers. Vacuum degassers utilize negative pressure to withdraw entrained gas from the mud. In order for this to work, mud is pumped through a venturi, which develops a negative pressure, thus sucking mud into the unit. The mud then flows over dispersion plates, arranged either horizontally or vertically, creating thin sheets of gas-cut mud. These dispersion plates bring entrained gas closer to the surface for easy removal by a stand-alone vacuum pump. The choice between horizontally or vertically mounted units is typically based on the footprint requirements of the specific rig.
Drilling mud vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost. Also, at the same time oilfield vacuum degassing machine can be invoked as a heavy-power agitator and supported applicable to all types of drilling mud purification system.
