    摘要: Novel solvents and methods of use for the removal of CO2 from flue gas, natural gas, hydrogen gas, synthesis gas, and other process and waste gas streams are provided. The solvent contains an alkali salt such as potassium carbonate and a polyamine such as piperazine (PZ) where the polyamine concentration is at least 1.5 equivalents/Kg H2O and the alkali salt concentration is at least 0.5 equivalents/Kg H2O. The preferred alkali salt/polyamine ratio is from approximately 1:2 to 2:1, and no additional alcohol is required for solubilizng the PZ. This chemical solvent and method of use provides efficient and effective removal of CO2 from gaseous streams and other sources.

    摘要: An acid gas such as carbon dioxide, hydrogen sulfide, or a mixture thereof is removed from gaseous streams using aqueous absorption and stripping processes. By replacing the conventional stripper used to regenerate the aqueous solvent and capture the acid gas with a multipressure stripper (51) that combines acid gas compression with stripping, less energy is consumed. The multipressure stripper is a multistage flash (52, 55, 59) in which the total vapor flow from each stage is compressed and fed to the bottom of the previous flash stage at a higher pressure. In this process, the heat in the water content of the vapor exiting each stage is utilized at a higher pressure in the previous stage. The described stripping process generates the acid gas at a higher pressure without operating the stripper at a higher temperature, thereby reducing the energy consumption of the system.

    摘要: A fitting and pipe section assembly 10 that is capable of being installed in tubing 20A and 20B of a jetted bath to render the tubing 20A and 20B adaptable to accept a close fit fluid flow device 30. The fitting and pipe section assembly 10 includes a pipe section 12, first and second fittings 18A and 18B, and first and second indicia 17A and 17B. The pipe section 12 has a center segment 16 between inlet and outlet end portions 14A and 14B. The inlet and outlet portions 14A and 14B may be placed in fluid flow communication with an inlet and an outlet of the tubing 20A and 20B. The first and second fittings 18A and 18B are disposed on the inlet and outlet portions of the pipe section 14A and 14B. The first and second indicia 17A and 17B on the pipe section 12 define the center segment 16 of the pipe section 12 and guide post-installation cutting of the pipe section 12 at predetermined points. The center segment 16 of the pipe section 12 may be selectively removed leaving the inlet and outlet portions 14A and 14B including the first and second fittings 18A and 18B. The fitting and pipe section assembly 10 may accept the close fit device 30 between the inlet and outlet portions 14A and 14B of the fitting and pipe section assembly 10.
