摘要： A method for preventing blockage of a cryogenic injection system is disclosed. The cryogenic injection system is provided comprising a gas feed line attached to a gas distributor. A gas is fed through the gas feed line and the gas distributor into a cryogenic liquid. A portion of the gas feed line passes through the cryogenic liquid. An insulative layer is provided for the portion of the gas feed line that passes through the cryogenic liquid. Heat transfer through the insulative layer between the portion of the gas feed line and the cryogenic liquid is countered sufficiently to prevent blockage of the gas feed line by a component or components of the gas. In this manner, blockage of the cryogenic injection system is prevented.

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： 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 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： 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.
