In an integrated coal gasification power plant, a humidifier is provided for transferring as vapor, from the aqueous blowdown liquid into relatively dry air, both (I) at least a portion of the water contained in the aqueous liquid and (II) at least a portion of the volatile hydrocarbons therein. The resulting humidified air is advantageously employed as at least a portion of the hot air and water vapor included in the blast gas supplied via a boost compressor to the gasifier.


In an integrated coal gasification power plant comprising, in combination: (a) a coal gasifier for producing a raw gaseous fuel by pressure gasification of coal with pressurized air and water vapor; (b) means for pressurizing hot air and water vapor and for supplying the pressurized air and water vapor to said gasifier as blast gas therefor; (c) a gas clean-up system adapted to (I) remove from said raw gaseous fuel at least a portion of any contaminants present therein and (II) produce (i) an aqueous blowdown liquid containing volatile hydrocarbons and (...
