摘要： A process for regasifying a fluid and generating electrical energy includes subjecting an operating fluid to 1) pumping, the pumping step including a low pressure pumping step 1a) and a high pressure pumping step 1b), 2) heating in a recuperator to obtain a heated flow, the heating step including a low temperature heat recovery step 2a) and a high temperature heat recovery step 2b), 3) further heating through a high temperature source to obtain a further heated flow, 4) expanding in a turbine, with generation of electrical energy to obtain an expanded flow, 5) cooling by heat exchange to obtain a cooled flow, and 6) condensing the flow of the operating fluid and regasifying the fluid. After low pressure pumping, a portion of the flow of the operating fluid is subjected to recompression to obtain a flow combined with the flow of the operating fluid obtained from step 2a).

摘要： A method for stripping CO2 from a biocatalyst-containing CO2-rich absorption solution to produce a biocatalyst-containing CO2-lean absorption solution and a CO2-rich gas is provided. The method includes generating a stripping gas from a portion of the biocatalyst-containing CO2-lean absorption solution in a stripping gas generation unit, and contacting the biocatalyst-containing CO2-rich absorption solution with the stripping gas in a gas-liquid contactor to produce the CO2-lean absorption solution and the CO2-rich gas.

摘要： CO2 capture processes and systems can be improved by recovering thermal energy from particular streams for reuse in the stripping stage. Thermal energy can be recovered from the overhead gas stream of a stripper operated under vacuum pressure conditions, and thermal energy can also be recovered from a flue gas. A heat transfer circuit can be implemented for recovering thermal energy by indirect heat transfer from the overhead gas stream, a flue gas stream, and/or other streams to a heat transfer fluid. The heat transfer circuit can include multiple heat recovery loops arranged in parallel and the heated fluid can be supplied through a reboiler of the stripper to heat the solution in the reboiler.

摘要： An anti-collision method includes storing information on a current position of at least one vehicle within a target work volume, scanning the target work volume by a radiofrequency radiation signal to detect the presence of at least one human operator within the target work volume, determining the current position of the at least one human operator within the target work volume, comparing the current position of the at least one human operator with the current position of the at least one vehicle, and, if the current position of the at least one human operator at least partially overlaps the current position of the at least one vehicle, activating at least one safety device.

摘要： Methods for enzyme-enhanced CO2 capture include contacting a CO2-containing gas with an aqueous absorption solution at process conditions—such as high temperature, high pH, and/or using carbonate-based solutions—in the presence of Thermovibrio ammonificans carbonic anhydrase (TACA) or functional derivative thereof for catalyzing the hydration reaction of CO2 into bicarbonate and hydrogen ions and/or catalyzing the desorption reaction to produce a CO2 gas. The TACA may be provided to flow with the solution to cycle through a CO2 capture system that includes an absorber and a stripper.
