摘要： A process for separating a vapor from a gas is disclosed. A cryogenic liquid is provided to an inlet of a froth flotation device. A carrier gas is provided to a gas distributor of the froth flotation device. The carrier gas comprises a product vapor. Bubbles of the carrier gas are produced and passed through the cryogenic liquid in the froth flotation device. A portion of the product vapor desublimates, condenses, crystallizes, or a combination thereof to produce a solid product and a product-depleted carrier gas. Bubbles of the product-depleted carrier gas collect the solid product as a froth concentrate. The froth concentrate is removed by overflowing out of the froth flotation device.

摘要： A method for removing a vapor from a carrier gas is disclosed. A heat exchanger is provided. A coolant is provided to the coolant side. A slurry is provided to the process side. The slurry comprises a contact liquid and scouring solids. The carrier gas is provided to the heat exchanger, the carrier gas comprising a vapor. A portion of the vapor desublimates, condenses, absorbs, or reacts such that the portion of the vapor solidifies to form a product solid. At least a portion of the product solid deposits as a foulant on an outer surface of the coolant side and is scoured with the scouring solids to remove the foulant from the outer surface of the coolant side. A vapor-depleted carrier gas is removed from the heat exchanger. The slurry and product solid from the heat exchanger. In this manner, the vapor is removed from the carrier gas.

摘要： Devices, systems, and methods for melting solids are disclosed. A vessel includes a solids inlet, a plunger, one or more fluid jets, and a fluid outlet. Solids are passed through the solids inlet into the vessel. The plunger is positioned adjacent to the solids inlet to provide a variable gap between the plunger and the solids inlet. The variable gap provides a restriction producing a back pressure at the solids inlet. Hot fluid is injected into the vessel by fluid jets. The one or more fluid jets enter the vessel and end adjacent to the variable gap. The hot fluid melts at least a portion of the solids.

摘要： A process for forming a solid product or products is disclosed. The process is provided with n desublimating exchangers. An exchanger E1 being associated with a first exchanger and an exchanger En being associated with an nth exchanger, n representing the number of exchangers. The n exchangers comprise at least one direct-contact exchanger comprising a contact fluid. A process fluid is passed through the n exchangers in order from E1 through En. The process fluid comprises a product component or components. The solid product or products form from the product component or components in the plurality of exchangers by desublimation. The solid product or products are separated from the process fluid. In this manner, a solid product or products is formed.

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： Devices, systems, and methods for separating solids from liquids are disclosed. A vessel includes an inlet, a carrier liquid outlet, a product outlet, a purifying section, and a heater. The inlet directs a slurry into the purifying section. The slurry comprises particles of a solid and a carrier liquid. The purifying section preferentially drives the particles of the solid towards a heating zone of the purifying section versus the carrier liquid. This displaces a first portion of the carrier liquid away from the heating zone of the purifying section. The heater heats the slurry. The carrier liquid outlet drives a majority of the carrier liquid out of the vessel. The product outlet is adjacent to the heating zone of the purifying section.

摘要： A device for thickening a cryogenic slurry is disclosed. The device comprises 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.
