Abstract

<PICT:0873890/III/1> An ammonia still comprises a column A having a plurality of bubble cap trays, an inlet L and outlet N for ammonia liquor feed and a mixture of steam and ammonia vapour respectively, a steam inlet O and an effluent liquor outlet M, the liquor fed to the inlet L being passed first through a heat exchanger E from inlet F to outlet G and preheated by vapour entering the heat exchanger at Q. Part of the vapour leaving the heat exchanger at R by line S is returned by a line T to a lower compartment of the column, vapour recirculation being achieved by means of a steam injector U. A U-bend Y provides a liquid seal between the outlet W for condensate formed in the heat exchanger E and its point of return to an intermediate position in the column A.
