ISO 9001 COMPANY

Vacuum dessification, a process for removing dissolved gases from water, is a unit operation in which the pressure  in the space above the water is sufficiently reduced  so that solubility of the gas is decreased to below the desired level. The dissolved gases are released from the water and removed by the evacuating system.  Sufficient packing must be present so that enough surface area between the gas and water is available to allow the gas present in the water  to reach the gas interface and finally be carried out by the evacuating system.

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 deaerator  in series with vacuum deaerator

When Carbon-dioxide removal is required, a forced draft deaerator is used prior to a vacuum deaerator.  Normally the carbon-dioxide effluent from the force draft deaerator should be about 10 ppm.
