    Abstract: A system for carbon dioxide capture from a gas mixture comprises a lean solvent comprising 3-amino-1-propanol (AP), 2-dimethylamino-2-methyl-1-propanol (DMAMP), and water; an absorber containing at least a portion of the lean solvent, wherein the absorber is configured to receive the lean solvent and a gaseous stream comprising carbon dioxide, contact the lean solvent with the gaseous stream, and produce a rich solvent stream and a gaseous stream depleted in carbon dioxide; a stripper, wherein the stripper is configured to receive the rich solvent stream; a cross-exchanger fluidly coupled to a rich solvent outlet on the absorber and a rich solvent inlet on the stripper; a reboiler fluidly coupled to a lower portion of the stripper; and a condenser fluidly coupled to a vapor outlet of the stripper.

    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.

    Abstract: A plant comprises a feed gas source, H2S removal unit, first absorber and a second, pressure reduction stages, first and second heat exchangers, stripping unit, and a conduit. The H2S removal unit selectively removes H2S from a feed gas from the feed gas source to produce an H2S depleted feed gas. The first absorber and the second absorber remove CO2 from the H2S depleted feed gas using a semi-lean and an ultralean solvent to produce a product gas and a rich solvent. The plurality of pressure reduction stages generates a cooled flashed solvent. The first heat exchanger and the second heat exchanger use the cooled flashed solvent to cool the H2S depleted feed gas and the semi-lean solvent. The stripping unit strips the flashed solvent with dried air to produce the ultralean solvent, and the conduit combines a portion of the ultralean solvent with the H2S depleted feed gas.

    Abstract: A method for operating a natural gas liquids processing (NGL) system, the system being selectively configured in either an ethane rejection configuration or an ethane recovery configuration, the method comprising, when the NGL system is in the ethane rejection configuration, collecting a reboiler bottom stream that, in the ethane rejection configuration, includes ethane in an amount of less than 5% by volume, and when the NGL system is in the ethane recovery configuration, collecting a reboiler bottom stream that, in the ethane recovery configuration, includes ethane in an amount of at least about 30% by volume.

    Abstract: Embodiments relate generally to reconfigurable modular processing facilities and methods for constructing and operating such. For example, a method for constructing a reconfigurable modular processing facility may comprise assembling a plurality of vertical walls, wherein the spaces between the walls define a plurality of stations; assembling a plurality of horizontal levels, wherein the spaces between the levels and the walls define the plurality of stations; constructing a lift within a center portion of the facility, wherein the lift is configured to access each of the plurality of stations; assembling one or more pods sized to fit within the stations, wherein the pods contain process equipment; configuring a process within the facility by moving one or more pods into one or more stations; and connecting the one or more pods to one another to complete the configuration of the process.
