Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A system for temporarily connecting an underwater station arranged on the bed of a body of water and a surface facility has an elongated conducting member with one end connected to the underwater station and one free end selectively and temporarily connectable to the surface facility; a marker buoy; and a cable connected to the free end of the elongated conducting member and to the marker buoy to quickly recover the free end of the elongated conductor element when it is necessary to connect the underwater station via the elongated conducting member to the surface facility.

Abstract: 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.
