EN-FAB Deaerators are widely used for the removal of oxygen, nitrogen, carbon dioxide and volatile organics from the feedwater to steam-generating boilers.
Two stage Operation
A possible means of reducing both capital and operating costs is the use of a two-stage vacuum deaerator (I.E. two vacuum deaerator operating in series). Each vacuum deaerator has its own evacuating system.
Forced Draft Degasifier In Series with Vacuum Deaerator Operation
When CO2, VOCc and other removal is required, a forced draft degasifier is used prior to a vacuum deaerator. Liquid is sprayed on the packing at the top of the column and, as it travels down through the packing, a film forms on the surface of the packing, allowing the release of entrained gases into the fan assisted counter-current air flow that passes up through the column. A mist eliminator/demister removes droplets from the air as it exits via the vent at the top of the column.
Areas of Application
EN-FAB engineers fully skidded, packaged vacuum deaerators and forced draft degasifier equipment for Heat Recovery Steam Generators (HRSG) and other applications.
