Patent number: 8269037Abstract: An absorption medium for removing acid gases from a fluid stream comprises an aqueous solution of a) of at least one metal salt of an aminocarboxylic acid, and b) of at least one acid promoter, wherein the molar ratio of b) to a) is in the range from 0.0005 to 1.0. The acid promoter is selected from mineral acids, carboxylic acids, sulfonic acids, organic phosphonic acids and partial esters thereof. The absorption medium, compared with absorption media based on amino acid salts, has a reduced regeneration energy requirement without significantly reducing the absorption capacity of the solution for acid gases. In a process for removing acid gases from the fluid stream, the fluid stream is brought into contact with the absorption medium.Type: GrantFiled: January 28, 2010Date of Patent: September 18, 2012Assignee: BASF SEInventors: Gerald Vorberg, Torsten Katz, Georg Sieder, Christian Riemann, Rupert Wagner, Ute Lichtfers, Erika Dengler

Patent number: 8231851Abstract: An exhaust gas containing a perfluoride compound (PFC) and SiF4 is conducted into a silicon remover and brought into contact with water. A reaction water supplied from a water supplying piping and air supplied from an air supplying piping are mixed with the exhaust gas exhausted from the silicon remover. The exhaust gas containing water, air, and CF4 is heated at 700° C. by a heater. The exhaust gas containing PFC is conducted to a catalyst layer filled with an alumina group catalyst. The PFC is decomposed to HF and CO2 by the catalyst. The exhaust gas containing HF and CO2 at a high temperature exhausted from the catalyst layer is cooled in a cooling apparatus. Subsequently, the exhaust gas is conducted to an acidic gas removing apparatus to remove HF. In this way, the silicon component is removed from the exhaust gas before introducing the exhaust gas into the catalyst layer.Type: GrantFiled: September 16, 2002Date of Patent: July 31, 2012Assignees: Hitachi, Ltd., Hitachi Information & Control Solutions, Ltd., Hitachi Kyowa Engineering Co., Ltd.Inventors: Kazuyoshi Irie, Toshihiro Mori, Hisao Yokoyama, Takayuki Tomiyama, Toshihide Takano, Shin Tamata, Shuichi Kanno
