Zusammenfassung:	1459153 Steel in evaporation apparatus HOOKER CHEMICALS & PLASTICS CORP 15 July 1974 [29 Nov 1973] 31182/74 Heading C7A In a process for evaporation, concentration and/ or purification of alkali metal chloride and hydroxide solutions, at least part of which is effected at over 50C, at least a part of the surfaces of the receiving chamber, flow through heating zone containing heat transfer elements, separation chamber for forming a liquid-vapour mixture, passageways and baffle and distribution means, which are in contact with the solution or its vapour at over 50C are formed of a ferritic stainless steel comprising:- the balance being Fe. Reference is made to the use of multiple (e.g. triple) effect evaporation systems.
