20120060689 | METHOD AND SYSTEM FOR REDUCING ENERGY REQUIREMENTS OF A CO2 CAPTURE SYSTEM - A method for reducing energy requirements of a CO | 03-15-2012 |
20120063975 | PROCESS GAS TREATMENT SYSTEM - A system is arranged to remove carbon dioxide (CO2) from a gas stream by bringing the gas stream into contact with a circulating ammoniated solution stream such that CO2 is removed from the gas stream by the ammoniated solution stream. A method of removing non-volatile compounds from the circulating ammoniated solution stream includes: introducing a portion of the circulating ammoniated solution stream into a gas-liquid separating device; and separating the introduced ammoniated solution into an ammonia rich gas phase and a liquid phase comprising the non-volatile compounds; and reintroducing the ammonia rich gas phase into the circulating ammoniated solution stream. | 03-15-2012 |
20120258031 | CARBON DIOXIDE CAPTURE SYSTEM - A chilled ammonia capture system for capturing carbon dioxide from a flue gas stream comprises a first absorber and a second absorber. The first absorber operates at a temperature of about 25 to about 50 degrees Celsius. The operating temperature permits the use of a lower circulation rate, which leads to smaller diameter vessels and to fewer recirculation pumps, which in turn leads to lower operating and maintenance costs. | 10-11-2012 |
20130000301 | LOW PRESSURE STEAM PRE-HEATERS FOR GAS PURIFICATION SYSTEMS AND PROCESSES OF USE - Systems for regenerating an absorbent solution include steam produced by a boiler; a set of pressure turbines fluidly coupled to the boiler for receiving the steam, wherein the set of pressure turbines comprises a high pressure turbine, a medium pressure turbine and a low pressure turbine; and a regenerating system comprising a regenerator for regenerating a rich and/or semi-rich absorbent solution to form a lean absorbent solution in fluid communication with a reboiler, the regenerating system fluidly coupled to the set of pressure turbines, wherein steam from the low pressure turbine provides a heat source for preheating the rich or the semi-rich absorbent solution fed to the regenerator. Also disclosed are processes of use. | 01-03-2013 |
20130125747 | LOW PRESSURE STRIPPING IN A GAS PURIFICATION PROCESS AND SYSTEMS THEREOF - Processes for operating an ammonia stripper at a low pressure in a gas purification system include providing a first side-draw stream from the ammonia stripper; heating the first side-draw stream with a second side-draw stream from a regenerator; providing a stripper offgas stream from the ammonia stripper to a stripper overhead condenser; and utilizing the stripper offgas stream as a heat source for a regenerating system fluidly coupled to the stripper overhead condenser. Also disclosed are systems for implementing the processes. | 05-23-2013 |
20130175004 | GAS TREATMENT SYSTEM WITH A HEAT EXCHANGER FOR REDUCTION OF CHILLER ENERGY CONSUMPTION - A gas treatment system including a heat exchanger having a first side and a second side separated from one another. The first side defines a first inlet and a first outlet and the second side defines a second inlet and a second outlet. A direct contact cooler is in fluid communication with the first outlet, a direct contact heater is in fluid communication with the first inlet and/or a gas polisher is in fluid communication with the first inlet and the first outlet. The gas treatment system includes an ammonia polishing system in fluid communication with the second inlet and/or the second outlet. | 07-11-2013 |

20130186272 | AMMONIA CAPTURING BY CO2 PRODUCT LIQUID IN WATER WASH LIQUID - A method for capturing ammonia present in combustion flue gas subjected to carbon dioxide removal, using a water wash unit ( | 07-25-2013 |
20130213224 | LOW PRESSURE STRIPPING IN A GAS PURIFICATION PROCESS AND SYSTEMS THEREOF - Processes for operating an ammonia stripper at a low pressure in a gas purification system include providing a first side-draw stream from the ammonia stripper; heating the first side-draw stream with a second side-draw stream from a regenerator; providing a stripper offgas stream from the ammonia stripper to a stripper overhead condenser; and utilizing the stripper offgas stream as a heat source for a regenerating system fluidly coupled to the stripper overhead condenser. Also disclosed are systems for implementing the processes. | 08-22-2013 |
