Abstract

A method for treating produced water or a feedwater stream with an evaporator. The feedwater stream or produced water is directed to and through a deaerator located upstream of the evaporator. Steam produced by the evaporator is utilized to strip dissolved gases from the produced water or feedwater stream passing through the deaerator. To efficiently strip dissolved gases, the vapor pressure in the deaerator is maintained at below atmospheric pressure and the produced water or feedwater stream is heated to a temperature greater than the saturated vapor temperature in the deaerator.
