ABSTRACT:
A process to efficiently remove sulfur compounds from a hydrocarbon stream in a refinery operation includes the production and recycle of hydrogen from the sulfur compounds. The sulfur compounds present in the hydrocarbon cut are converted to hydrogen sulphide which is split to hydrogen and sulfur in a non-thermal plasma reactor.
