Water deaerator WHITTIER

vacuum

Vacuum deaerators, also known as vacuum degasifiers, use a vertical pressure vessel, multiple vacuum stages and vacuum pumps to continuously remove objectionable gases from liquids. Packed towers, supported by powerful vacuum pumps, reduce the surrounding vapor partial pressure which promotes the mass transfer from the liquid to the gas phase. Features A vacuum deaerator system consists of the tower with integral catch basin, vacuum pump and forwarding pump. Demisters and condensers on the vacuum lines are employed to protect the vacuum pumps from corrosion and damage by moisture entrained in the gas stream. Water seals are an integral design of the forwarding pumps to prevent the re-introduction of air into the water. Finally, level transmitters are utilized to control the feedwater flow rate, prevent flooding and protect the forwarding pumps from cavitation. Veolia can provide stand-alone degassers with capacities ranging from 100 to 10,000 gpm for a single unit, or complete systems that can include vacuum towers, liquid ring vacuum pumps, ejectors, mass transfer packing, chemical oxygen scavenger dosing skids and transfer pumps. Veolia selects materials of construction to provide effective corrosion resistance under the most aggressive service conditions. Benefits Veolia’s proprietary system design provide the best value in the market by optimizing the tower diameter, number of stages, packed bed geometry and vacuum capacity on the basis of the salinity, temperature, and other conditions of the influent water.
