摘要： Devices, systems, and methods for pressure-regulated melting are disclosed. A vessel includes a solids inlet, a fluids outlet, a cavity, and an energy source. Solids enter the vessel through the solids inlet. The cavity has an internal pressure. A backpressure is induced in the solids inlet. The energy source heats the vessel, the contents of the vessel, or a combination thereof. The rate of heating of the energy source is matched to a feed rate of the solids such that the solids are melted directly to a product liquid at the internal pressure. The product liquid passes through the fluids outlet through a restriction that maintains the internal pressure in the cavity.

摘要： Devices, systems, and methods for pressure-regulated melting are disclosed. A vessel includes a solids inlet, a fluids outlet, a cavity, and a warm fluids inlet. Solids enter the vessel through the solids inlet. The cavity has an internal pressure. Warm fluids enter the vessel through the warm fluids inlet. The warm liquid being directed into the vessel provides an inlet pressure that produces a backpressure in the solids inlet. A feed rate of the warm liquid is matched to a feed rate of the solids such that the solids are melted directly to a product liquid at the internal pressure. The product liquid is passed out of the vessel through a restriction that maintains the internal pressure in the cavity.

摘要： Devices, systems, and methods for pressure-regulated melting are disclosed. A vessel includes a solids inlet, a fluids outlet, a cavity, and a melting device. Solids enter the vessel through the solids inlet. The cavity has an internal pressure. The solids inlet has a reducer that produces a first back pressure on the solids in the solids inlet. The melting device heats the vessel, the contents of the vessel, or a combination thereof. The heating rate of the melting device is matched to the feed rate of the solids such that the solids are melted directly to a product liquid at the internal pressure. The product liquid passes through the fluids outlet through a restriction that maintains the internal pressure in the cavity.

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 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 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.
