Degasser how does it work

In a vacuum degasser tower, water flows by gravity down through a tower filled with packing as a vacuum is drawn on the tower. The packing in the tower has a very high surface area, disperses the water very effectively, thereby enhancing the removal of O 2 , CO 2 and N 2. Performance is further enhanced by using atomizing nozzles as the water enters the tower. This ensures efficient and continuous gas removal, even if the liquids are transported through the degassing chamber at high flow rates.

For highest user-comfort and long lifetime of the degasser, it is also important. A debubbler is a wonderful tool for easy removal of visible bubbles from water-based liquid flow streams. Our patented design includes a vertical bubble trap, a gas-permeable membrane, and a vacuum source.

Additionally, degassing for all drilling fluid can be ensured by increasing the drilling fluid throughput capacity beyond the maximum flow rate from the well. Over inclined plates, the mud should spill over the trough and this allows the gas to be released as the mud spreads over a large surface area.

In the vapor space, the vacuum plays an important role too as the mud carries over the plates as evenly as possible. Once this process has occurred, the gas can either be burned away from the rig or vented through a vent line from the tank. What happens to the mud now free from gas? Mud can then be sent to the active pit, but not before the safety valves jump into action.

If the working pressure reduces, these valves stop the mud from coming into contact with the vacuum pump and therefore being sent back up the degasser. Cormack, D.

Vacuum degasser working principle According to Henry's law, the gas solubility in water is related with water temperature and pressure. Technical characteristics of vacuum degasser. Eliminate the pump cavitation, reduce operating noise.
