Waste treatment system
Patent
·
OSTI ID:5128168
This patent describes a method of processing hazardous waste. It comprises: incinerating the hazardous waste to a temperature sufficient to break down the hazardous waste; collecting the solids produced by the incineration step; directing at least a portion of the exhaust gas stream produced by the incineration step through a spray dryer; passing all of the gas stream from the incineration step including that portion exiting the spray dryer through a scrubbing and absorbing device to remove particulates and acid gas from the gas stream by contacting the gas stream with a scrubbing and acid gas absorbing slurry or solution; separating a portion of the scrubbing and acid gas slurry or solution liquid after contact with the gas stream as a waste liquor; spraying the waste liquor into the exhaust gas stream passing through the spray dryer to evaporate the water in the waste liquor and produce a dry residue; and collecting the dry residue so that there is no liquid waste output from the system.
