20080241036 | METHOD AND DEVICE FOR SEPARATION OF SULPHUR DIOXIDE FROM A GAS - A system for separating sulfur dioxide from a gas using an aqueous absorption liquid. The system includes a housing, an apertured plate, an outlet box, a distribution mechanism, a container, and a pump. The housing has an inlet and an outlet. The apertured plate is positioned between the inlet and the outlet and includes a lower side, an upper side, and apertures fluidly connecting the lower and upper sides. The outlet box includes a distribution mechanism that is arranged so that the absorption liquid draining from the outlet box contacts the gas from the inlet before the gas passes through the apertures in the apertured plate. The container contains the absorption liquid and is fluidly connected with the housing. The pump draws the absorption liquid from the container through the pump and through a conduit to the upper side of the apertured plate. | 10-02-2008 |
20090101012 | MULTI-STAGE CO2 REMOVAL SYSTEM AND METHOD FOR PROCESSING A FLUE GAS STREAM - An ammonia based CO2 capture system and method is provided in which multiple absorption stages are provided.

20110120308 | SINGLE ABSORBER VESSEL TO CAPTURE CO2 - A system for removing carbon dioxide from a flue gas stream is provided, the system comprising an absorber vessel configured to receive a flue gas stream, the absorber vessel comprising a first absorption stage configured to receive the flue gas stream and contact it with a first ionic solution, a second absorption stage configured to receive flue gas which has passed the first absorption stage and contact it with a second ionic solution, a first sump vessel, and a second sump vessel. Furthermore, a method for removing CO | 05-26-2011 |
20110173981 | UTILIZATION OF LOW GRADE HEAT IN A REFRIGERATION CYCLE - A system for reducing the power required to cool a combustion gas for cleaning and a method for performing the same are disclosed. The system includes an expander for producing power. Energy in the form of heat is transferred from the combustion gas to a working fluid. The working fluid drives the expander to generate at least a portion of the power required for performing to drive a compressor in a refrigeration system. After the combustion gas transfers energy the combustion gas is cooled with the refrigeration system. In some embodiments the expander and the compressor are arranged along a common shaft. | 07-21-2011 |
20130028807 | METHOD AND SYSTEM FOR REMOVAL OF CARBON DIOXIDE FROM A PROCESS GAS - Disclosed is a method of removing carbon dioxide from a process gas, the method comprising: contacting an ammoniated solution with the process gas in an absorption arrangement | 01-31-2013 |
20130064748 | METHOD AND APPARATUS FOR CAPTURING SOx IN A FLUE GAS PROCESSING SYSTEM - Systems and processes for treating a flue gas for removing sulfur oxides (SOx) entrained in the flue gas generally includes contacting the gas stream with an aqueous alkali and/or alkaline earth metal hydroxide solution such as sodium hydroxide and reacting SOx entrained in the gas stream to form an aqueous alkali and/or alkaline earth metal sulfur-containing salt solution such as sodium sulfate. The aqueous alkali and/or alkaline earth metal sulfur-containing salt solution can be introduced into an electrodialysis apparatus configured to electrolyze water to form hydrogen and hydroxyl ions that selectively combine with alkali and/or alkaline earth metal ions and sulfur containing ions from the aqueous alkali and/or alkaline earth metal sulfur containing salt feedstream to form a regenerated alkali and/or alkaline earth metal hydroxide feedstream and an acid containing feedstream. | 03-14-2013 |
