Patent number: 10537828Abstract: A method for preventing fouling of a demister is disclosed. A process fluid is provided into a vessel. A gas is provided to a gas inlet of the vessel. The gas comprises a component that desublimates, crystallizes, solidifies, reacts, or a combination thereof, in the process fluid, forming a first solid. The gas is passed through the process fluid, the component of the gas forming the first solid, resulting in a component-depleted gas. The component-depleted gas is passed out of the process fluid, causing splashing or spurting of the process fluid and the first solid. The diverter section is provided between the demister and the gas inlet, the diverter section comprising a physical obstruction preventing the process fluid and the first solid from splashing or spurting onto the demister. In this manner, fouling of the demister is prevented.Type: GrantFiled: April 12, 2017Date of Patent: January 21, 2020Assignee: Sustainable Energy Solutions, LLCInventors: Larry Baxter, Andrew Baxter, Kyler Stitt, Aaron Sayre, Stephanie Burt, David Frankman, Nathan Davis

Patent number: 10533796Abstract: A method for thickening a cryogenic slurry is disclosed. The method comprises providing a cryogenic slurry flow path, a cryogenic liquid discharge path, and a filter medium between the cryogenic slurry flow path and the cryogenic liquid discharge path. The cryogenic slurry comprises a solid and a cryogenic liquid. The cryogenic slurry is fed into the cryogenic slurry flow path, generally tangential to the filter medium. This causes a portion of the cryogenic liquid to cross the filter medium into the cryogenic liquid discharge path as a cryogenic liquid discharge and the cryogenic slurry to thicken to produce a thickened slurry. The filter medium comprises a cryogenically-stable material such that adsorption of gases is inhibited, deposition of solids is prevented, and temperature-change induced expansion and contraction of the filter medium is optimized.Type: GrantFiled: March 9, 2017Date of Patent: January 14, 2020Inventors: Larry Baxter, Eric Mansfield, Kyler Stitt, David Frankman, Skyler Chamberlain, Nathan Davis, Stephanie Burt, Steven Malone
