GAS TO OLEFINS PROCESS WITH COPRODUCTION OF HYDROGEN TOGETHER WITH HEAT INTEGRATION PROCESS

摘要

The present disclosure relates in its first aspect to a process for converting a stream comprising methane into chemicals, said process is remarkable in that it comprises the steps of providing a first stream (1, 5, 11) comprising methane, providing a second stream (79) which is a bromine-rich stream, putting into contact said first stream (15) with said second stream (79) to obtain a third stream (21) comprising at least unreacted methane, methyl bromide, dibromomethane, and hydrogen bromide, removing said dibromomethane from said third stream (21), to produce a dibromomethane stream (103) and a fourth stream (27) comprising unreacted methane, methyl bromide and hydrogen bromide which is converted into chemicals, and separating hydrogen bromide said fourth stream (27), to provide a hydrogen bromide-rich stream. In its second aspect, the present disclosure concerns an installation for carrying out the process of the first aspect.
