Regeneration Of An Aqueous Solution From An Acid Gas Absorption Process By Matrix Stripping

US Patent:7901488, Mar 8, 2011
-
Filed:Oct 2, 2007
-
Appl. No.:11/865853

Abstract:Carbon dioxide and other acid gases are 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 matrix stripping configuration, less energy is consumed. The matrix stripping configuration uses two or more reboiled strippers at different pressures. The rich feed from the absorption equipment is split among the strippers, and partially regenerated solvent from the highest pressure stripper flows to the middle of sequentially lower pressure strippers in a “matrix” pattern. By selecting certain parameters of the matrix stripping configuration such that the total energy required by the strippers to achieve a desired percentage of acid gas removal from the gaseous stream is minimized, further energy savings can be realized.

Abstract:Compositions and methods related to the removal of acidic gas. In particular, the present disclosure relates to a composition and method for the removal of acidic gas from a gas mixture using a solvent comprising a diamine (e. g. , piperazine) and carbon dioxide. One example of a method may involve a method for removing acidic gas comprising contacting a gas mixture having an acidic gas with a solvent, wherein the solvent comprises piperazine in an amount of from about 4 to about 20 moles/kg of water, and carbon dioxide in an amount of from about 0. 3 to about 0. 9 moles per mole of piperazine.

US Classification:95236, 423228
-
Abstract:Novel solvents and methods of use for the removal of COfrom 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 HO and the alkali salt concentration is at least 0. 5 equivalents/Kg HO. 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 COfrom gaseous streams and other sources.

Abstract:The present disclosure relates to improved processes for treating hot sulfur-containing flue gas to remove sulfur therefrom. Processes in accordance with the present invention include preparing an aqueous slurry composed of a calcium alkali source and a source of reactive silica and/or alumina, heating the slurry to above-ambient temperatures for a period of time in order to facilitate the formation of sulfur-absorbing calcium silicates or aluminates, and treating the gas with the heat-treated slurry components. Examples disclosed herein demonstrate the utility of these processes in achieving improved sulfur-absorbing capabilities. Additionally, disclosure is provided which illustrates preferred configurations for employing the present processes both as a dry sorbent injection and for use in conjunction with a spray dryer and/or bagfilter. Retrofit application to existing systems is also addressed.

Carbon Capture: Pipe Dream or Key to our Energy Challenges?
view source- cheap. The consumers [are] going to see an increase in the cost of electricity of 5 to 10 cents per kilowatt hour, said Gary Rochelle, a chemical engineer at the University of Texas in Austin who has developed a technology to rinse carbon dioxide out of power plant smokestack emissions. Thats aNot everyone shares his optimism for clear federal policy, however. Were still five years away (from implementing CCS technology), said Gary Rochelle. Five years ago we were five years away, and until we pass cap-and-trade legislation, well always be five years away.
