摘要： A device and process for removing vapors from a gas is disclosed. A tower is provided. Sub-cooled pellets are distributed by the solids distributor across a horizontal cross-section of the tower. A process gas, comprising a product vapor, passes through the gas inlet. The product vapor and the sub-cooled pellets comprise the same material. The product vapor and the sub-cooled pellets agglomerate as the product vapor desublimates onto the sub-cooled pellets, forming product pellets and a vapor-depleted gas. A crushing device, a screening device, and a solids heat exchanger are provided. A portion of the product pellets are recycled as sub-cooled pellets to the solids distributor by crushing and screening the portion of the product pellets to the size distribution of the sub-cooled pellets and cooling the portion of the product pellets to produce the sub-cooled pellets.

摘要： A method for semi-continuous operation of a heat exchange process that alternates between two heat exchangers is disclosed. The method comprises, first, providing a contact liquid to a first heat exchanger while the second heat exchanger is on standby. The contact liquid contains a dissolved gas, an entrained gas, or residual small particles that foul the first heat exchanger by condensing or depositing as a foulant onto the first heat exchanger, restricting free flow of the contact liquid. Second, detecting a pressure drop across the first heat exchanger. Third, switching flows of the coolant from the first to the second heat exchanger. Fourth, removing the foulant from the now standby first heat exchanger by providing heat to the heat exchanger, passing a non-reactive gas through the heat exchanger, or a combination thereof. In this manner, the heat exchange process operates semi-continuously.

摘要： 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.

摘要： An air-sparged hydrocyclone for separating a vapor from a carrier gas is disclosed. The cyclone comprises a porous sparger covered by an outer gas plenum. A cryogenic liquid is injected to a tangential feed inlet at a velocity that induces a tangential flow and a cyclone vortex in the air-sparged hydrocyclone. The carrier gas is injected into the cyclone through the porous sparger. The vapor dissolves, condenses, desublimates, 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.

摘要： Condensable vapors such as carbon dioxide are separated from light gases in a process stream. The systems and methods employ a circulating fluidized particle bed cooled by an out-bed heat exchanger to desublimate the solid form of condensable vapors from the process stream. Gas and solids may be sorted in a separator, and the solids may then be subcooled in a heat exchanger. The condensable vapors may be condensed on the bed particles or in the heat exchanger while the light gases from the process stream, which are not condensed, form a separated light-gas stream.

摘要： A method for removal of a foulant from a carrier gas is disclosed. A solids conveyance device that spans a vessel and a solids coolant system are provided. A cold solid foulant is provided to the solid inlet of the vessel. The carrier gas containing the foulant is provided to the carrier gas inlet of the vessel. The foulant condenses or desublimates onto the recycled solid foulant, forming a foulant-depleted carrier gas and a solid foulant product. The solids conveyance device passes the solid foulant product out of the vessel. The foulant-depleted carrier gas leaves the vessel. The solid foulant product is split into a final solid foulant product and a recycled solid foulant. The recycled solid foulant is cooled through the coolant system to produce the cold solid foulant. In this manner, the foulant is removed from the carrier gas.

摘要： A method and device are disclosed herein for distributing a gas into a vessel. The method comprises providing a gas distribution apparatus, wherein an exposed surface of the apparatus comprises a material that inhibits adsorption of the gas and deposition of the gas' solid form. The material chosen is chemically repulsive to the gas and the gas' solid form. In this manner, desublimation of the gas and deposition of the gas' solid form onto the exposed surface is prevented. The device disclosed herein is the gas distribution apparatus referenced above.

摘要： Devices, systems, and methods for a heat exchanger and operation of a heat exchanger are disclosed. The heat exchanger comprises a chamber with a plurality of fluid inlets and a plurality of fluid outlets. The chamber comprises plates, the plates being parallel and defining fluid plenums between each of the plates. The fluid plenums define a fluid flow path, wherein each of the fluid plenums are aligned with one of the plurality of fluid inlets, one of the plurality of fluid outlets, a fluid path between at least two of the fluid plenums, or a combination thereof. The plates are mounted on guides perpendicular to a plane of the plates. The plates move along the guides due to changes in pressure in the fluid plenums, application of an external force to the one or more plates, or a combination thereof.

摘要： A system and a method for removing solid buildup from a filter media is disclosed. A slurry is passed parallel across a cross-flow filter, the filter comprising a conductive filter media and the slurry comprising a carrier liquid and solids. A portion of the carrier liquid crosses through the filter media as a permeate while a thickened slurry continues parallel to the filter media. A blockage of at least a portion of the filter media is detected. The blockage comprises a portion of the solids. At least a portion of the filter media is heated to a melting temperature of the solids, such that a portion of the blockage melts, whereby the blockage is cleared.
