Abstract

The invention discloses an ultra-pure methane chloride production system which comprises a reaction system for producing methane chloride by a methanol gas-phase hydrochlorination dry method and a carbon tetrachloride conversion reaction system. The two systems are sequentially connected with a sulfuric acid drying system and a methane chloride rectification system to obtain a methane chloride finished product; the sulfuric acid drying system is further connected with a compressor, and a gas outlet of the compressor is connected with a top gas outlet of the methane chloride rectification system to be mixed into a reaction system for producing methane chloride from crude methane chloride to methane chloride through a gas-phase thermal chlorination method. With a reaction system for producing methane chloride through the methane chloride gas phase thermal chlorination method, obtained mixed gas obtained after methane chloride and chlorine react sequentially enters a steam generation system, a chiller III, a condensation separation system, a dehydrogenation system, a dichloromethane refining system, a trichloromethane refining system and a carbon tetrachloride refining system. The system provided by the invention realizes full-process coupling energy conservation, energy conservation and emission reduction, the condition of single product proportion is changed, and free adjustmentof the proportion of the whole series of products and composite dehydration of the whole system are realized.

Description

technical field [0001] The invention relates to the technical field of an ultra-high-purity methane chloride production system and a process method, in particular to an ultra-high-purity methane chloride production system and a process. Background technique [0002] The production capacity of a single set of methane chloride is small, the consumption is high, and there are many by-products. The ratio of dichloromethane to chloroform is basically 1:1, the adjustment range is small, and the purity is ordinary grade. Crude monochloromethane has a high moisture content, and the device is severely corroded. The two-step reaction heat, material heat and material cooling are not comprehensively utilized. The by-product carbon tetrachloride is mainly used for supporting the production of tetrachlorethylene, which has a long production process, large investment and many wastes. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior a...
