Appl. No.:

13/309923

Inventors:

Dennis W. Johnson - Simpsonville SC, US
Jonathan Priest - Charlotte NC, US

Assignee:

FLUOR TECHNOLOGIES CORPORATION - Aliso Viejo CA

International Classification:

B01D 53/74
B01D 53/14

US Classification:

96243, 261160, 261 75, 422168

Abstract:

Post-combustion conditioning systems are described that include a flue gas conditioning device configured to condition an exhaust stream to produce a conditioned stream. First and second outlet ducts can be fluidly coupled to, and substantially supported by, the flue gas conditioning device. This advantageously can eliminate costly ductwork, reduce the space required, and reduce the pressure drop of the system. The first outlet duct can fluidly couple the flue gas conditioning device to an exhaust duct, such that the conditioned stream can flow from the first conditioning device via the first outlet duct.

International Classification:

US Classification:

4232421, 95229, 422170

Abstract:

A flue gas treatment process and system is presented. The system includes a fan capable of moving a flue gas through a flue gas desulfurizer, direct contact cooler, and COabsorber, without the need for a booster fan. The system also includes a direct contact cooler and CO2 absorber that are configured to withstand gas conditions present at the flue gas desulfurizer exit. When the direct contact cooler and COabsorber are shutdown, the speed of the fan is lowered and the flue gas continues to flow through the cooler and CO2 absorber and out a chimney. The overall cost of installing, operating, and maintaining the system is lower than that of conventional processes and systems.
