| titleOfInvention | Method and device for recovering methyl chloride from byproduct hydrochloric acid |
| abstract | The invention relates to a method and a recovery device for recovering chloromethane from byproduct hydrochloric acid, wherein the analysis temperature and the low pressure condition of the method are simultaneously satisfied, so that the chloromethane in the byproduct hydrochloric acid is thoroughly separated, and the purity of the chloromethane is more than 98 percent; the mass concentration of the hydrochloric acid is 20-25%, wherein the content of chloromethane is below 100 ppm; the analysis process is simple, the operation is easy, no chemical reagent is needed, and the method is safe and environment-friendly. The recovery device has the advantages of small investment, easy operation, environmental protection, effective separation and recovery of chloromethane in the byproduct hydrochloric acid, suitability for separation and recovery of other methane chlorides in the byproduct hydrochloric acid, and remarkable technical and economic benefits. |
