An apparatus and method for removing carbon dioxide gas from beer. The apparatus includes a preheater, a degas column, a degas condenser, an optional degas condensate receiver, an optional degas condensate pump, and a bottoms pump. The apparatus is arranged to receive a feed from a beer source into the preheater and output the heated beer in the degas column. Much of the vapor in the degas column is condensed to a liquid phase by the degas condenser, and residual vapor is directed to-an existing carbon dioxide scrubber. The liquid phase is then reintroduced to the degas column via the degas condensate receiver and degas condensate pump. The degassed beer is pumped from the bottom of the degas column, through the beer preheater, and finally on to the existing distillation system.

A system and method for the pyrolysis of a pyrolysis feedstock utilizes a pyrolysis reactor having a pyrolysis conduit and a solids return conduit segment. Each segment is configured with an outlet and an inlet to receive and discharge solid materials that are circulated through the reactor through the different segments. A solids conveyor is disposed within the pyrolysis conduit segment to facilitate conveying solid materials from the solids inlet upward through the pyrolysis conduit segment toward the solids discharge outlet. A pyrolysis feedstock is introduced into the pyrolysis reactor and at least a portion of the feedstock is converted to pyrolysis gases within the pyrolysis conduit segment, which are discharged through a gas outlet.

A gas capture plant is provided. The gas capture plant includes an absorption tower for dissolving an object gas that requires regeneration in a lean absorbent liquid to produce rich absorbent liquid. A regeneration tower heats the rich absorbent liquid produced in the absorption tower to produce the lean absorbent liquid from which the regeneration gas is separated and the produced lean absorbent liquid is supplied back to the absorption tower. A gas condensing device condenses the regeneration gas received from the regeneration tower to separate condensate and target gas, thereafter, supplying the separated condensate to the regeneration tower, and exhausting the separated target gas. The gas condensing device includes a condenser and a reflux apparatus disposed within one housing and the condenser is disposed above the reflux apparatus.

Systems and methods generate steam mixed with desired non-condensable gas concentrations using a direct steam generator. Injecting the steam into a reservoir may facilitate recovering hydrocarbons from the reservoir. Cooling an output of the direct steam generator produces water condensate, which is then separated from the non-condensable gas, such as carbon dioxide. Reducing pressure of the condensate subsequently heated by cross-exchange with effluent of the direct steam generator regenerates the steam with the carbon dioxide removed for the injection.

An eductor condenser unit with an eductor assembly having a venturi-restricted flow path for receives a pressurized coolant fluid. A second flow path for receiving the discharged pyrolysis gases intersects the venturi-restricted flow path so that the received pyrolysis gases are combined with the coolant fluid and are discharged together to a mixing chamber that is used to condense pyrolysis gases.

The invention discloses a condenser for a bioreactor exhaust, comprising: an inlet (1) adapted to be fluidically connected to a bioreactor exhaust port (2), a cooling chamber (3; 103) fluidically connected to the inlet and via a filter device (4) to an outlet (5), a cooling conduit (6; 106) in contact with the cooling chamber, a heating conduit (7) in contact with the filter device and a vortex tube (8) arranged to convey a cold gas stream through the cooling conduit and to convey a hot gas stream through the heating conduit.

A method for cryogenic cooling without fouling is disclosed. The method comprises providing a first cryogenic liquid saturated with a dissolved gas; expanding the first cryogenic liquid into a separation vessel, separating into a vapor, a second cryogenic liquid, and a first solid; drawing the vapor into a heat exchanger and the second cryogenic liquid and the first solid out of the separation vessel; cooling the vapor against a coolant through the heat exchanger, causing the vapor to form a third cryogenic liquid and a second solid, the second solid dissolving in the third cryogenic liquid; and combining the second cryogenic liquid and the first solid with the third cryogenic liquid, producing a final cooled slurry. In this manner, the cryogenic cooling is accomplished without fouling.

A plant for dealcoholising alcoholic beverages includes a rectification column having at least one inlet for the alcoholic beverage, a sump and a top. The rectification column is operable such that dealcoholised beverage can be removed from the sump and exhaust vapour can be removed from the top. At least one evaporator is configured to supply the rectification column with vapour. A condenser arrangement condenses the exhaust vapour removed from the top of the rectification column, at least in part. The plant further includes a heat pump which can operate the evaporator as well as the condenser arrangement. A method for dealcoholising alcoholic beverages in a rectification column is also disclosed.

An improved system for separating gas from a process stream by providing a stripping unit at the overhead stream of a fractionation column to selectively and effectively remove the gas using a stripping fluid without providing a dedicated light-ends separations unit. The stripper unit may be connected to the reflux drum at the overhead stream. The system for separating gas further achieves greater thermodynamic efficiency by means of a split column design using mechanical vapor recompression with the reboiler and condenser integrated in a falling-film evaporator- or thermosiphon-type vapo-condenser.

A system and devices for treating and purifying fluids such as water. The system includes multiple devices and moves water through the devices. The system may include a steam boiler. The steam boiler may be connected to a steam stripper. Fluids may flow through the steam boiler and fed into the bottom of the steam stripper. The system may have salt treatment modules and carbon compound modules. The system may include desalination modules. The system may provide outputs of purified water, salt, and/or concentrated salt brine.
