  • Patent number: 10717039
    Abstract: 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.

  • Patent number: 10155193
    Abstract: A vertically oriented co-current contacting system and methods for separating impurities from a gas stream including a vertically oriented co-current contactor (VOCC) located in-line within a pipe, a vertically oriented mixer (VOM) including an annular support ring configured to maintain the VOM within the pipe, a number of radial blades configured to allow a liquid stream to flow into the VOM, and a central gas entry cone configured to allow a gas stream to flow through a hollow section within the VOM, a vertically oriented mass transfer section downstream of the VOM. The VOM and the vertically oriented mass transfer section provide for efficient incorporation of liquid droplets including impurities from the gas stream formed from the liquid stream into the gas stream. The vertically oriented co-current contacting system also includes a separation system configured to remove the liquid droplets.
