A PROCESS FOR REMOVING SULFUR FROM A FUEL GAS STREAM

摘要

Disclosed is a process for removing sulfur from a fuel gas stream that co mprises an organic sulfur compound and a light olefin. The process includes introducing a fuel gas stream into an elongated hydrotreating reactor vessel in which it is contacted with a hydrodesulfurization catalyst under hydrode sulfurization process conditions. A quench gas stream is also introduced int o the elongated hydrotreating reactor vessel at a location below the point o f introduction of the fuel gas stream. A reactor effluent is yielded that co ntains hydrogen sulfide and a significantly reduced organic sulfur concentra tion that is below the organic sulfur concentration of the fuel gas stream.
