| 20110139003 | Method and device for separating carbon dioxide from a waste gas of a fossil fueloperated power plant - A method for separating carbon dioxide from a flue gas of a fossil fuel-operated power plant is provided. In the method, a fossil fuel is initially burned in a combustion process, wherein a hot waste gas containing carbon dioxide is produced. In a next process step, waste gas containing carbon dioxide is brought into contact with an absorption medium in an absorption process, wherein carbon dioxide is absorbed by the absorption medium, thus forming a charged absorption medium. Next, gaseous carbon dioxide is thermally expelled from the charged absorption medium in a desorption process. For this purpose, a vapor is supplied to the desorption process, the vapor is injected into the charged absorption medium, wherein the condensation heat released by the condensation of the vapor is transferred to the charged absorption medium, and the partial pressure of the carbon dioxide is simultaneously reduced in the desorption unit. | 06-16-2011 |
| 20110309295 | Absorbing agent, method for manufacturing an absorbing agent and use of an absorbent agent - An absorbent agent is provided. The absorbent agent is particularly for separating carbon dioxide from the flue gas of a fossil-fired combustion device. The absorbent agent comprises a two-component mixture including a free amino acid and an amino acid salt, wherein the free amino acid exhibits a surplus compared to the amino acid salt based on the molar concentration. This creates variability in the PCBN value, which may be attained through different absorption and desorption process temperatures. A method for manufacturing the absorbent agent is also provided. | 12-22-2011 |

| 20150034867 | METHOD AND DEVICE FOR TREATING A CONTAMINATED ALKALINE AMINO ACID SALINE SOLUTION - A method for treating a contaminated alkaline amino acid salt solution is provided. First, carbon dioxide is introduced into the amino acid salt solution, with the result that carbonate or carbonate salts is or are precipitated, these being filtered off. The remaining filtrate is then cooled, amino acid or amino acid salts being crystallized out and likewise being filtered off. The amino acid or amino acid salt is then dissolved again, with the result that a treated amino acid salt solution is recovered. | 02-05-2015 |
