Abstract: The present disclosure relates to methods and systems for sweetening natural gas may utilize a water wash to achieve a reduction in raw natural gas stream contaminants (e.g., particulate contaminants and/or chemical contaminants) and/or to recover solvent used for removing H2S and CO2 from the natural gas. For example, a method may include contacting a first natural gas stream with a first water stream in a co-current contacting system to produce a second natural gas stream and a second water stream, wherein the first natural gas stream comprises natural gas, an acid gas, and a contaminate, and wherein a concentration of the contaminate in the second natural gas stream is less than a concentration of the contaminate in the first natural gas stream; and removing at least a portion of the acid gas from the second natural gas stream.

Abstract: A method for recovering sulfur within a gas processing system is described herein. The method includes contacting a natural gas stream including an acid gas with a solvent stream within a co-current contacting system to produce a sweetened natural gas stream and a rich solvent stream including an absorbed acid gas. The method also includes removing the absorbed acid gas from the rich solvent stream within a regenerator to produce a concentrated acid gas stream and a lean solvent stream. The method further includes recovering elemental sulfur from hydrogen sulfide (H2S) within the concentrated acid gas stream via a sulfur recovery unit.

Abstract: A method for regenerating liquid desiccant is described herein. The method includes co-currently contacting a rich desiccant stream including water with a stripping gas within a co-current contacting system such that the stripping gas removes at least a portion of the water from the rich desiccant stream, producing a wet stripping gas and a lean desiccant stream. The method also includes removing the water from the wet stripping gas within a stripping gas separation system, regenerating the stripping gas, and recirculating the stripping gas to the co-current contacting system.

Abstract: Methods are provided for removing fine particles from crude oils extracted from mined oil sands using a non-aqueous extraction solvent. A bitumen derived from non-aqueous extraction of oil from oil sands can undergo optional physical separation to remove larger particles and then processed using electrostatic filtration to remove particle fines. This can allow for production of a bitumen product from a non-aqueous extraction process that has a sufficiently low particle content to be suitable for pipeline transport.

Abstract: The embodiments of the disclosure relate generally to absorbent processes, systems, and methods. The disclosure includes the use of a combination of thermal regeneration and gas assisted stripping to convert a rich CO2 absorbent to a lean CO2 absorbent via an intermediate semi-lean CO2 absorbent. The system includes a regenerator and a stripper to convert the rich CO2 absorbent to the lean CO2 absorbent, and can further include a combustor and an absorber. A fuel gas can be used as the stripping gas, thereby producing a CO2-rich fuel gas, which can be recycled to a combustor to reclaim the fuel value.
