Patent number: 10155193Abstract: 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.Type: GrantFiled: May 2, 2014Date of Patent: December 18, 2018Assignee: ExxonMobil Upstream Research CompanyInventors: J.
