Embodiment Construction

[0016] The present invention will be further described with reference to accompanying drawing:

[0017] A kind of technique of reclaiming organic matter in hydrogen chloride gas according to the present invention comprises the following process steps:

[0018] (1) Input the mixed gas produced by the methane chloride generating device into the organic matter absorption tower. The mixed gas mainly includes gas phase organic matter and hydrogen chloride gas. The organic matter is mainly monochloromethane and dichloromethane. The organic matter absorption tower is fed into Methane chloride is used as an absorbent to absorb the mixed gas, the organic matter in the mixed gas is integrated into the methane chloride, and the hydrogen chloride gas in the mixed gas is discharged;

[0019] (2) The hydrogen chloride gas discharged from the organic matter absorption tower is sent to the hydrogen chloride absorber, and hydrochloric acid is used in the hydrogen chloride absorber to absorb th...

Abstract

The invention discloses process for recovering organic matters in hydrogen chloride gas and equipment used by same. The process comprises the following steps of: (1) inputting mixed gas generated by a methane chloride generation device into an organic matter absorption tower, importing methane chlorides into the organic matter absorption tower as an absorbent to absorb the mixed gas, blending organic matters in the mixed gas in the methane chlorides and exhausting hydrogen chloride gas in the mixed gas; and (2) conveying the hydrogen chloride gas exhausted from the organic matter absorption tower to a hydrogen chloride absorber and absorbing the hydrogen chloride gas in the hydrogen chloride absorber by adopting hydrochloric acid. The invention has the advantages that the organic matters in the mixed gas are absorbed, thereby achieving the purpose of recycling the organic matters in the hydrogen chloride, and the process flow is compact and reasonable. Compared with the prior art, the invention has simple process steps and can greatly reduce the cost, and the like.

Description

technical field [0001] The invention relates to the technical field of recovering organic matter in hydrogen chloride gas, in particular to a process for recovering organic matter in hydrogen chloride gas produced by a methane chloride generating device and equipment used therein. Background technique [0002] At present, the existing domestic methane chloride generating devices will generate a large amount of mixed gas during production. The main components of the mixed gas are hydrogen chloride gas and gas phase organic matter. The organic matter is mainly monochloromethane and dichloromethane. The organic matter needs to be recovered. It is used again as a raw material for a methane chloride generator. At present, when most domestic manufacturers recover organic matter in hydrogen chloride gas, they usually absorb hydrogen chloride with water (or dilute acid), then dry the remaining gas that has absorbed hydrogen chloride with sulfuric acid, and then pressurize and cryoge...
