    摘要： A co-current contactor for separating components in a fluid stream, the co-current contactor comprising a first inlet configured to receive the fluid stream proximate to a first end of the co-current contactor, a second inlet configured to receive a solvent proximate the first end of the co-current contactor, and a mass transfer section configured to receive the fluid stream and the solvent and to provide a mixed, two-phase flow, wherein the mass transfer section comprises a surface feature along an inner surface of the mass transfer section configured to reduce film flow along an inner wall of the mass transfer section, and wherein the surface feature comprises at least one of a hydrophobic surface, a superhydrophobic surface, a porous wall surface, and a nonlinear surface irregularity extending radially inward or radially outward along the inner surface of the mass transfer section.

    摘要： A method of separating impurities from a natural gas stream. The natural gas stream is cooled through heat exchange with one or more process streams to produce a chilled gas stream, which is contacted with a lean solvent stream in a contactor to separate hydrogen sulfide (H2S) from the chilled gas stream, thereby producing a rich solvent stream and a partially-treated gas stream. Carbon dioxide (CO2) and H2S are separated from the partially-treated gas stream in a membrane separation system, thereby creating a fully-treated gas stream and a permeate gas stream, the permeate gas stream being comprised primarily of H2S and CO2, and the fully-treated gas stream being comprised primarily of natural gas. The fully-treated gas stream and the permeate gas stream are at a lower temperature than the partially-treated gas stream. The fully-treated gas stream and the permeate gas stream comprise the one or more process streams.

    摘要： A method of separating impurities from a natural gas stream. CO2 and H2S are separated from the natural gas stream in a membrane separation system, thereby creating a partially-treated gas stream and a permeate gas stream, both of which are at a lower temperature than the natural gas stream. The partially-treated gas stream is contacted with a first lean solvent stream in a first contactor to separate H2S from the partially-treated gas stream, thereby producing a first rich solvent stream and a fully-treated gas stream. The permeate gas stream is contacted with a second lean solvent stream in a second contactor to separate H2S therefrom to produce a second rich solvent stream and a CO2 gas stream. H2S and CO2 are removed from the first and second rich solvent streams, thereby producing the first and second lean solvent streams.
