Abstract
The present invention provides a process for purifying natural gas, comprising removing mercaptans from a natural gas stream by a combination of an amine-based separation unit and a selective oxidation unit to obtain a purified natural gas stream, wherein at least part of the mercaptans are converted into at least elemental sulphur in the selective oxidation unit by selective catalytic oxidation.
