Abstract

165,833. Fairweather, J. H. July 9, 1919. Ammoniacal liquor, treating. - Ammoniacal liquor is evaporated to expel free ammonia, and the residual liquor is returned to the gas circuit after passing through a heat exchanger for the incoming liquor. The process is repeated until the residual liquor is sufficiently concentrated to be worked up separately for the recovery of fixed ammonia. The free ammonia driven off may be converted directly into sulphate, or condensed to a concentrated liquor; in the latter case, the weak liquor, before entering the evaporator, may be treated with steam to liberate carbon dioxide and sulphuretted hydrogen.
