Abstract

1508836 Urea production MITSUI TOATSU CHEMICALS Inc 1 July 1975 [8 July 1974] 27772/75 Heading C2C [Also in Divisions B1 C7 and F4] Urea is prepared from ammonia and carbon dioxide in the head of a heat exchanger where a non-corrosive material, liquid ammonia, flows in a gap between the inner surface and the outside of an inner member, to protect the inner surface from corrosion by the reactants (see Division B1).
