Abstract
The present disclosure relates in its first aspect to a process of converting a stream comprising methane into chemicals, said process being 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 and 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; wherein the fourth stream (27) is converted into chemicals. In its second aspect, the present disclosure concerns an installation for carrying out the process of the first aspect.
