Abstract
A method for the cooling and separation of chlorides and fluorides from hot mixtures of gases generated by the gasification of solid or liquid fuels or by extracting gas from solid fuels by cooling the gas mixture in the presence of a circulating liquid of ammonia and water in a cooler at a temperature below the adiabatic saturation temperature. This results in condensation of the steam contained in the gas and the formation, by sublimation of the gaseous ammonia, HCl or HF, of solid ammonium chloride or ammonium fluoride. These solids become dissolved in the condensed steam or the liquid circulated in the cooler and are then discharged from the cooler.
