Abstract

Reivindicación 1: Proceso para producir cloruro de metilo por hidrocloración integrado a un reactor de conversión de DME, siendo que el DME proviene de la producción de HPMC, y estando dicho proceso caracterizado porque comprende: (a) alimentar el reactor de DME de lecho fijo con una corriente de MeCl y HCl proveniente del proceso de producción de MeCl; (b) alimentar el reactor de DME de lecho fijo con una corriente de DME:HCl seco proveniente del proceso de producción de HPMC; (c) secar la mezcla MeCl:HCl:H₂O; (d) enfriar la corriente proveniente de la etapa (c); y (e) separar el MeCl y el HCl a través de una columna de destilación.Claim 1: Process for producing methyl chloride by hydrochlorination integrated into a DME conversion reactor, where the DME comes from the production of HPMC, and said process being characterized in that it comprises: (a) feeding the fixed-bed DME reactor with a stream of MeCl and HCl from the MeCl production process; (b) feeding the fixed bed DME reactor with a dry DME:HCl stream from the HPMC production process; (c) drying the MeCl:HCl:H₂O mixture; (d) cooling the stream from step (c); and (e) separating MeCl and HCl through a distillation column.
