64 Hydrocyclone For Cryogenic Gas-Vapor Separation US15439177 2017-02-22 US20180236397A1 2018-08-23 Larry Baxter; Christopher Hoeger; Aaron Sayre; Skyler Chamberlain; Kyler Stitt; Eric Mansfield; Stephanie Burt; Andrew Baxter; Jacom Chamberlain; Nathan Davis
A hydrocyclone for separating a vapor from a carrier gas is disclosed. The hydrocyclone comprises one or more nozzles. A cryogenic liquid is injected to a tangential feed inlet at a velocity that induces a tangential flow and a cyclone vortex in the hydrocyclone. The carrier gas is injected into the cryogenic liquid, causing the vapor to dissolve, condense, desublimate, or a combination thereof, forming a vapor-depleted carrier gas and a vapor-enriched cryogenic liquid. The vapor-depleted carrier gas is drawn through a vortex finder and the vapor-enriched cryogenic liquid is drawn through an apex nozzle outlet. In this manner, the vapor is removed from the carrier gas.
