Methods are provided for reducing the quantity of acid gas reinjected into a reservoir by partial COremoval processes. The methods include acid gas removal, acid gas enrichment, generation of a COrich stream and an HS rich stream, and reinjection of the HS rich stream into the reservoir. The acid gas enrichment can be performed by a solvent-based acid gas enrichment unit, a membrane-based acid gas enrichment unit, or a combination of a solvent-based acid gas enrichment unit a and membrane-based acid gas enrichment unit. The system includes an acid gas removal unit, one or more acid gas enrichment units, and an acid gas reinjection compressor. The acid gas enrichment unit can be a solvent-based acid gas enrichment unit, a membrane-based acid gas enrichment unit, or a solvent-based acid gas enrichment unit and a membrane-based acid gas enrichment unit.

Reservoir management by controlling acid gas build-up in reservoir by partial CO2 removal processes

Provided herein are methods and systems for treating a tail gas of a Claus process to remove sulfur-containing compounds. The method includes combusting a tail gas of a Claus process in an excess of oxygen gas to yield a thermal oxidizer effluent. The thermal oxidizer effluent includes sulfur dioxide, water vapor, and oxygen. The effluent is routed to a quench tower and contacted with a dilute aqueous acid quench stream to yield sulfurous acid, hydrated sulfur dioxide, or both. The sulfurous acid or hydrated sulfur dioxide is oxidized with the excess oxygen from the thermal oxidizer effluent to yield sulfuric acid.

Treating sulfur dioxide containing stream by acid aqueous absorption

Methods and systems for increasing efficiency of combustion in a turbine, methods including expanding in an expansion unit a pressurized fluid stream to form an expanded, cooled fluid stream; exchanging heat between an oxygen containing stream and the expanded, cooled fluid stream to reduce temperature of the oxygen containing stream to a reduced temperature and create a reduced temperature turbine compressor inlet oxygen containing stream; and compressing the reduced temperature turbine compressor inlet oxygen containing stream to an operating pressure of the turbine, where the step of compressing the reduced temperature turbine compressor inlet oxygen containing stream is more efficient than compressing the oxygen containing stream.
