ABSTRACT:
A process utilizing a sorbent in a manner which provides a greater and more efficient utilization of the sorbent for the removal of sulfur, or sulfur-containing compounds, from a process stream
wherein a sulfur-containing process stream is passed through a fixed-bed of sorbent from one side of the bed to the opposite side, sulfur removed, and passage of the sulfur-containing process stream through said fixed-bed of sorbent continued to breakthrough of sulfur from the exit side of the bed. Then the direction of flow of the sulfur-containing process stream is reversed without desorption of the sulfur from the sorbent, and passage of the sulfur-containing process stream in said reverse direction through the bed again continued until breakthrough of sulfur from the side of the sorbent bed opposite the former entry side. In a preferred embodiment, two or more of the fixed-beds of sorbent are staged, or placed in series.
