    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 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.
