Patent number: 8673227Abstract: A system for removal of carbon dioxide from a process gas includes an absorption arrangement arranged to allow contact between the process gas and an ammoniated solution within the absorption arrangement such that at least a part of the carbon dioxide of the process gas is captured by the ammoniated solution. The absorption arrangement is arranged to, with regard to the ammoniated solution, only accommodate ammoniated solution without solids. A first heat exchanger is arranged to cool the ammoniated solution including captured carbon dioxide after it has exited the absorption arrangement. A separator is arranged to remove at least a part of any solids in the cooled ammoniated solution. A second heat exchanger is arranged to heat the ammoniated solution after it has exited the separator and returned to the absorption arrangement.Type: GrantFiled: October 8, 2012Date of Patent: March 18, 2014Assignee: ALSTOM Technology LtdInventors: Sean E. Black, Sanjay K. Dube, David J. Muraskin, Frederic Z. Kozak

Patent number: 8518156Abstract: A process and system (100) for removing contaminants from a solution to regenerate the solution within the system. The process includes providing a solution (165) from a wash vessel (160) to a stripping column (181), the solution (165) including contaminants removed from a flue gas stream (150) present in the wash vessel (160) and contacting the solution with steam (185) inside the stripping column (181) thereby removing the contaminants from the solution and regenerating the solution. The stripping column (181) is operated at a pressure less than about 700 kilopascal.Type: GrantFiled: August 3, 2010Date of Patent: August 27, 2013Assignee: ALSTOM Technology LtdInventors: Frederic Z. Kozak, Arlyn V. Petig, Ritesh Agarwal, Rameshwar S. Hiwale

Patent number: 8292989Abstract: A power generation plant (112), a method, and a CO2 capture system (122) for removing carbon dioxide (104) from a flue gas stream (106) are disclosed. As shown in FIG. 2, a CO2 capture system (122), comprises an absorber vessel (202), a water wash vessel (210), and a stripper (214). The CO2 capture system (122) can be configured to introduce both a lean ionic ammonia solution (204) from a regeneration system (124) and a flue gas stream (106) from a cooling system (120) and to provide a rich ionic ammonia solution (206) to a regeneration system (124), wherein the introduction of the lean ionic ammonia solution (204) to the flue gas stream (106) produces a flue gas substantially devoid CO2 (224). The water wash vessel (210) can be configured to receive the flue gas substantially devoid CO2 (224) and produce ammoniated water (212) by introducing water (218) to the flue gas substantially devoid CO2 (224).Type: GrantFiled: October 30, 2009Date of Patent: October 23, 2012Assignee: ALSTOM Technology LtdInventors: Frederic Z. Kozak, Arlyn V. Petig, Vikram Shabde
