Abstract: A system for reducing SO2 emissions comprises a hydrogenation reactor, a tail gas cooler, a contact condenser, a hydrolysis reactor, and an absorber. The hydrogenation reactor is configured to receive a Claus tail gas and convert at least a portion of SO2 in the Claus tail gas to H2S to produce a hydrogenated Claus tail gas stream. The hydrolysis reactor is configured to convert at least a portion of COS to H2S. The absorber comprises an amine-based solvent and is configured to absorb at least a portion of the H2S and recycle the H2S to the Claus plant.

Abstract: Elemental sulfur carrying capacity of a hydrocarbonaceous solvent is improved by first loading the solvent with sulfur and subsequent hydrotreatment under conditions that convert at least some of the elemental sulfur in the sulfur loaded solvent to hydrogen sulfide while preserving at least 95% of the monoaromatic and polyaromatic components in the solvent.

Abstract: A natural gas liquid plant is retrofitted with a bolt-on unit that includes an absorber that is coupled to an existing demethanizer by refrigeration produced at least in part by compression and expansion of the residue gas, wherein ethane recovery can be increased to at least 99% and propane recovery is at least 99%, and where a lower ethane recovery of 96% is required, the bolt-on unit does not require the absorber, which could be optimum solution for revamping an existing facility. Contemplated configurations are especially advantageous to be used as bolt-on upgrades to existing plants.

Abstract: A LNG liquefaction plant includes a propane recovery unit including an inlet for a feed gas, a first outlet for a LPG, and a second outlet for an ethane-rich feed gas, an ethane recovery unit including an inlet coupled to the second outlet for the ethane-rich feed gas, a first outlet for an ethane liquid, and a second outlet for a methane-rich feed gas, and a LNG liquefaction unit including an inlet coupled to the second outlet for the methane-rich feed gas, a refrigerant to cool the methane-rich feed gas, and an outlet for a LNG. The LNG plant may also include a stripper, an absorber, and a separator configured to separate the feed gas into a stripper liquid and an absorber vapor. The stripper liquid can be converted to an overhead stream used as a reflux stream to the absorber.

Abstract: Embodiments relate generally to methods and systems for processing a gas stream and for removing mercaptans from a feed stream. A method may comprise compressing a semi-treated gas stream, wherein the semi-treated gas stream comprises organic sulfur species and acid gas components; contacting the semi-treated gas stream with a lean solvent; removing at least a portion of the organic sulfur species and acid gas components from the semi-treated gas stream to produce a treated gas stream and a semi-rich solvent stream; contacting a feed gas stream with the semi-rich solvent, wherein the feed gas stream comprises organic sulfur species and acid gas components; and removing at least a portion of the organic sulfur species and acid gas components from the feed gas stream to produce the semi-treated gas stream based on contacting the semi-rich solvent with the feed gas stream.
