Continuous biomass extraction system and process
A method for producing valuable organic liquid from a biomass wherein a heated gas is mixed with a biomass to produce an enriched organic vapor and a biomass waste product. The biomass waste product is separated from the enriched organic vapor. The enriched organic vapor is cooled to produce a liquid organic oil and the liquid organic oil is collected. A system for producing the liquid organic oil including a first separation unit to separate an enriched organic vapor and a biomass waste product. The enriched organic vapor and the biomass waste product are generated from mixing a heated gas and a biomass. The system also includes a wet scrubber for cooling the enriched organic vapor to generate an enriched organic smoke. The organic smoke can be transformed to the liquid organic oil in an electrostatic precipitator.
CO2 CAPTURE SYSTEM

The CO2 capture system comprises: a CO2 capture device that captures CO2; a flow path that delivers an exhaust gas emitted from a building to the CO2 capture device; a flow rate regulator that regulates a flow rate of the exhaust gas; and a control unit that controls the flow rate regulator to regulate the flow rate of the exhaust gas.
CARBON DIOXIDE RECOVERY DEVICE
A carbon dioxide recovery device provided with a separation device that separates carbon dioxide from to-be-separated gas (for example, combustion exhaust gas) containing carbon dioxide, wherein: in order from the upstream side where the to-be-separated gas is supplied, the separation device and carbon dioxide sublimators, which sublimate (solidify) carbon dioxide that was separated in the separation device, are connected in series, refrigerant circuits in which a fluid having cold heat serves as the refrigerant, are connected to the carbon dioxide sublimators, and the refrigerant is used to sublimate (solidify) the carbon dioxide; and when the carbon dioxide is sublimated (solidified), the carbon dioxide sublimators are depressurized and set to negative pressure so as to draw in the carbon dioxide separated at the separation device.
Apparatus and process for producing a deacidified fluid stream
A process for producing a deacidified fluid stream from a fluid stream comprising methanol and at least one acid gas and an apparatus for carrying out the process. The process comprising a) an absorption step in which the fluid stream is contacted with an absorbent in an absorber to obtain an absorbent laden with methanol and acid gases and an least partly deacidified fluid stream; b) a regeneration step in which at least a portion of the laden absorbent obtained from step a) is regenerated in a regenerator to obtain an at least partly regenerated absorbent and a gaseous stream comprising methanol, water and at least one acid gas; c) a recycling step in which at least a substream of the regenerated absorbent from step b) is recycled into the absorption step a); d) a condensation step in which a condensate comprising methanol and water is condensed out of the gaseous stream from step b); e) a distillation step in which at least a portion of the condensate from step d) is guided into a distillation column to obtain a top stream comprising methanol and a bottom stream comprising water; which comprises recycling at least a portion of the bottom stream from step e) into the regenerator.
Calcination Process
Described is the use of a mineral comprising a metal carbonate fraction and a fuel fraction, such as oil shale or coal shale, in a calcination process. The disclosed process can advantageously result in carbon dioxide being removed from the atmosphere. Further, in the process, heat energy generated during calcination can be used to separate oxygen from air, so that the oxygen can be fed back into the system. Alternatively or in addition, heat energy may also be used to compress the gaseous carbon dioxide generated from the calcination process.

Method and device for recycling and purifying water vapor from coal drying process
A method and device are provided for purifying and recycling water vapor from a coal drying process. Included are a temperature-lowering and dehumidifying process, a flash distillation stripping process, and a vacuum condensing process. A condensing tower receives a temperature-lowered exhaust gas with high humidity from a cooling tube and a condensed water of 5˜60° C. from a flash distillation tank, allowing the exhaust gas and the condensed water to contact each other in a vapor-liquid reverse manner, to lower the temperature and dehumidify the exhaust gas. The flash distillation tank performs a vacuum flash distillation to the condensing water pumped therein from the condensing tower. Water vapor of 5˜60° C. evaporated through flash distillation in the flash distillation tank enters into the demisting washer to be dehumidified and then is condensed. The condensed water in the vapor condenser is transferred into a recycled water tank. Non-condensable gas is discharged out.

Method to condense and recover carbon dioxide (CO2) from CO2 containing gas streams
A method to condense and recover CO.sub.2 from CO.sub.2 containing streams. A first step involve providing at more than one heat exchanger, with each heat exchanger having a first flow path for passage of a first fluid and a second flow path for passage of a second fluid. A second step involves passing a stream of very cold natural gas sequentially along the second flow path of each heat exchanger until it is heated for distribution and concurrently passing a CO.sub.2 containing stream sequentially along the first flow path of each heat exchanger, allowing the water vapor portion of the CO.sub.2 containing stream to condense and precipitate on the condensing heat exchangers. A third step involves passing a water vapor free CO.sub.2 containing stream to a cryogenic heat exchanger to condense, precipitate and recover CO.sub.2. This processes results in the recovery of CO.sub.2 and water vapor from CO.sub.2 containing streams using condensing heat exchangers, chiller, compressor, expander and power generator to recover the low value thermal heat available in CO.sub.2 containing waste streams.
