20090205492 | REDUCING CARBON DIOXIDE (CO2) EMISSIONS FROM THE BURNING OF A FOSSIL FUEL - A system for reducing carbon dioxide emissions from gasses generated in burning fossil fuel, includes a vessel, separator and reheater. The upper portion of the vessel receives downward flowing, first type solid particles capable of absorbing heat from upward flowing gasses and second type solid particles capable of capturing carbon dioxide from the gasses. The separator separates the second type solid particles with the captured carbon dioxide from the gasses discharged from the first vessel discharge, and directs the separated second type solid particles with the captured carbon dioxide to a separator discharge. The reheater directs the first type solid particles and the second type solid particles with the captured carbon dioxide in a downwardly flow to a first reheater discharge, such that heat from the first type solid particles causes the captured carbon dioxide to be released from the second type solid particles. | 08-20-2009 |

20120111243 | CONTROL VALVE AND CONTROL VALVE SYSTEM FOR CONTROLLING SOLIDS FLOW, METHODS OF MANUFACTURE THEREOF AND ARTICLES COMPRISING THE SAME - Disclosed herein is a solids flow control valve comprising a standpipe; a shoe; and a transport pipe; wherein the standpipe is in operative communication with the shoe and lies upstream of the shoe; the standpipe comprising a first end and a second end, where the first end is in contact with a source that contains disposable solids and the second end is in fluid contact with the shoe; the shoe being operative to restrict the flow of the disposable solids; the transport pipe being disposed downstream of the shoe to receive and transport the solids from the shoe. | 05-10-2012 |
20120111535 | ORIFICE PLATE FOR CONTROLLING SOLIDS FLOW, METHODS OF USE THEREOF AND ARTICLES COMPRISING THE SAME - Disclosed herein is an orifice plate comprising one or more plates having orifices disposed therein; the orifices being operative to permit the flow of solids from a moving bed heat exchanger to a solids flow control system; where the orifice plate is downstream of a tube bundle of the moving bed heat exchanger and upstream of the solids flow control system and wherein the orifice plate is operative to evenly distribute the flow of solids in the solids flow control system. | 05-10-2012 |
20120125240 | SYSTEM AND METHOD OF MANAGING ENERGY UTILIZED IN A FLUE GAS PROCESSING SYSTEM - A method is provided for managing an amount of energy utilized by a carbon dioxide capture system. The method includes providing a fuel and a feed stream to a combustion system. The feed stream includes oxygen and a portion of a flue gas stream generated upon combustion of the fuel. The method also includes subjecting the flue gas stream to a carbon dioxide capture system to remove carbon dioxide therefrom, measuring a concentration of oxygen present in the feed stream, and selectively adjusting an amount of the flue gas stream included in the feed stream based on the measured concentration of oxygen in the feed stream. The selective adjustment is performed such that the feed stream maintains an oxygen concentration in a range of between about 10% to 90% by volume and the carbon dioxide capture system operates at an energy load between 1.4 GJ/ton of carbon dioxide and 3.0 GJ/ton of carbon dioxide. | 05-24-2012 |
20120129113 | SYSTEM AND METHOD OF MANAGING ENERGY UTILIZED IN A FLUE GAS PROCESSING SYSTEM - A method for managing an amount of energy utilized by a carbon dioxide capture system that includes providing a fuel and a feed stream including oxygen to a combustion system. The feed stream includes a portion of a flue gas stream generated upon combustion of the fuel in the combustion system. The flue gas stream is subjected to a carbon dioxide capture system to remove carbon dioxide therefrom and an amount of at least one of an oxygen stream or the portion of the flue gas stream introduced to the feed stream is adjusted such that the feed stream maintains an oxygen concentration in a range of between 10% to 90% by volume and the carbon dioxide capture system operates at an energy load between about 1.4 GJ/ton of carbon dioxide and about 3.0 GJ/ton of carbon dioxide. | 05-24-2012 |
20140065559 | PRESSURIZED OXY-COMBUSTION POWER BOILER AND POWER PLANT AND METHOD OF OPERATING THE SAME - A pressurized oxy-combustion circulating fluidized bed power plant having a circulating fluidized bed boiler is provided. A combustion chamber of the boiler is in fluid communication with a separator and configured so that solids produced during combustion enter the separator. The power plant further includes an air separation unit that is in fluid communication with the combustion chamber. The air separation unit is configured to supply substantially pure oxygen to the combustion chamber at a pressure greater than 1 bar. An external heat exchanger is in fluid communication with the separator and in fluid communication with the combustion chamber. The external heat exchanger is configured so that a portion of the solids received in the separator pass through the external heat exchanger and transfer heat to a working fluid, after which the solids are returned to the combustion chamber to moderate or control the temperature in the combustion chamber. | 03-06-2014 |
