ABSTRACT:
Toxic trace element pollutants present in the raw product gas and raw flue gas streams produced during the gasification of coal or similar carbonaceous solids containing sulfur and such trace elements are recovered by separately scrubbing the product gas and flue gas with water, combining the resulting aqueous effluents, and removing the pollutants from the combined aqueous stream as insoluble metal sulfides.
