  • Treatment of effluent
    Patent number: 4085688
    Abstract: Contaminated aqueous alkali wash liquor from the treatment of gases containing hydrogen sulphide and/or hydrogen cyanide is reconstituted by treatment at an elevated temperature in a reducing atmosphere followed by quenching to form reconstituted wash liquor. The contaminated liquor is concentrated, before entering the reducing atmosphere, by direct contact with hot gases derived from the hot reducing atmosphere. Quenching and concentration are carried out by interaction of a gaseous medium with a liquid spray. Generation of the hot reducing atmosphere, reaction of the contaminated liquor with the hot reducing atmosphere, and concentration of the contaminated liquor may be carried out in a single chamber.
