REMOVAL OF DISSOLVED GASES FOR BOILER FEED WATER PREPARATION

摘要

Method for removing dissolved gases from water to produce boiler feed water in a catalytic steam reforming process where boiler feed water is heated by indirect heat transfer with a reformate stream and/or a combustion product gas stream and the boiler feed water subsequently flash vaporized to form steam and residual liquid water, where the steam formed by flash vaporization strips the dissolved gases from the water.
