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.
La présente invention concerne un procédé de purification de gaz naturel, qui comprend lélimination des mercaptans dun courant de gaz naturel par une combinaison dune unité de séparation à base damine et dune unité doxydation sélective pour obtenir un courant de gaz naturel purifié. Selon linvention, au moins une partie des mercaptans est transformé en au moins du soufre élémentaire dans lunité doxydation sélective par une oxydation catalytique sélective.
