CIRL Proposals for the Design and Control of 2500 M cubed/Hr Methyl Chloride Chlorinators

Group II Technical Note, ICI Central Instrument Research Lab.
S F Bush with P A Sinclair.
Summary
This note summarises the design of new large chlorinators for a projected single stream chloromethanes plant taking 2500 M3/hr of methyl chloride and producing methylene chloride and chloroform down to a weight ratio of 0.7 to 1. This design is based on the CIRL theory of chlorination stability and is sized for operation at 45 psig (current operation 25-30 psig). The control strategy proposed is designed to be implemented by any combination of manual single loop and computer control; numerical values have still to be supplied.
