    摘要： A fractionation system for removing heavy hydrocarbons in a gas stream. A stripping section receives a predominantly liquid phase of the feed gas stream. A co-current contacting system receives a predominantly vapor phase of the feed gas stream. The co-current contacting system includes a compact contacting bundle disposed within a vessel and including a plurality of substantially parallel contacting units, each of the plurality of contacting units having a droplet generator, a mass transfer section, and a separation system. Each droplet generator generates droplets from a liquid disperses the droplets into a gas stream. Each mass transfer section provides a mixed, two-phase flow having a vapor phase and a liquid phase. Each separation system separates the vapor phase from the liquid phase such that the concentration of heavy hydrocarbons in the vapor phase is lower than in the liquid phase.

    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 fractionation system for removing heavy hydrocarbons in a gas stream. A stripping section receives a predominantly liquid phase of a feed gas stream. First and second co-current contacting systems are located in-line within a pipe. The first co-current contacting system receives a predominantly vapor phase of the feed gas stream. Each co-current contacting system includes a co-current contactor and a separation system. Each co-current contactor includes a droplet generator and a mass transfer section. The droplet generator generates droplets from a liquid and disperses the droplets into a gas stream. The mass transfer section provides a mixed, two-phase flow having a vapor phase and a liquid phase. The separation system separates the vapor phase from the liquid phase.
