Latest Patents

J Michael Lawrence holds a patent for a process for the treatment of sulfur-containing gases. This process utilizes the Claus reaction, employing a recycle stream containing a reactive component in a negative feedback mode. This method maintains the sulfur-producing Claus reaction at approximately equilibrium conditions. The feedstream may contain hydrogen sulfide or sulfur dioxide in a minor amount within an inert gas background. In one embodiment, the feedstream to the reaction zone contains a stoichiometrically excess amount of sulfur dioxide for the Claus reaction. Effluent from the reaction zone is then passed to a hydrogenation zone where the sulfur dioxide is converted to hydrogen sulfide. Hydrogen sulfide is extracted from the hydrogenation zone effluent and recycled to the Claus reaction zone. In another embodiment, the feedstream may contain a stoichiometrically excess amount of hydrogen sulfide. The effluent from the reaction zone is treated to produce a hydrogen sulfide-containing recycle stream, which is then subjected to at least partial oxidation to produce a converted stream containing sulfur dioxide. This converted stream is recycled back to the reaction zone. The invention is particularly useful in the high-pressure processing of hydrocarbon gases containing sulfur.
