Deaerator Venting – What is acceptable Today.
In a steam deaerator, steam serves as the scrubbing agent to reduce the partial pressures of the gases being removed. The phenomenon of gas removal from water through the use of scrubbing in a deaerator can be accomplished in several different ways.
With the scrubbing action occurring, the deaerator must vent the non-condensable gases into atmosphere. Therefore, the only acceptable steam venting from a steam system operation is the Deaerator venting of non-condensable gases with a very small percentage of steam. To accomplish this goal of venting non-condensable gases; the deaerator will vent a small percentage of steam.
With the high cost of steam today, the deaerator vent must be investigated to insure excessive venting of steam is not occurring. Our Steam Group Members have found steam losses that have exceeded $ 100,000.00 a year cause unnecessary venting from the deaerator.
