ABSTRACT:
A waste liquor treatment system comprising an evaporator in combination with a gas cooler, said evaporator providing fractional distillation of waste liquor, thereby separating the liquor into its several components of gaseous vapors, purified water and concentrated brine and said gas cooler providing thermal energy from its waste heat to run the evaporator. The evaporator consists of a boiler section, a condenser section, a vacuum pump, a liquor circulating pump and nozzles for extracting the products. The gas cooler may be one or two stage. In the one stage cooler, the hot liquor which condenses in the gas cooling process provides energy for the evaporator through means of a heat exchanger. In the two stage gas cooler, the hot liquor in the first stage is circulated directly to the boiler section of the evaporator. The hot liquor from the second stage is circulated through a separate heat exchanger.
