摘要： A headgear assembly for a baghouse filter can include a headgear configured to allow for concentric arrangement of first and second filters coupled thereto, where at least one of the first filter, second filter, and headgear can include an opening through which accumulated particulate from the second filter can pass. The headgear assembly can also include a cleaning assembly configured to facilitate cleaning of at least one of the first and second filters. Methods of facilitating on-line cleaning of a baghouse filter are also described wherein an exhaust stream is passed through concentrically arranged first and second filters to produce a filtered stream. At least one of the first and second filters can be cleaned using a cleaning assembly to remove accumulated particulate, which can pass through an opening in at least one of the first filter, the second filter, and the headgear.

摘要： Systems and methods directed to cleaning a flue gas are described, in which a column housing can be configured to receive a feed stream, and includes an absorber configured to produce a clean stream that is substantially depleted of at least one of SOx and CO2. The absorber can comprise at least one of (1) a primary CO2 capture system disposed downstream of a gas conditioning system and (2) a primary acid gas removal system disposed upstream of a gas conditioning system. The gas conditioning system can also be disposed in the column housing.

摘要： Systems and methods are described for reducing the start-up time of flue gas conditioning processes. Such processes can include a gas removal unit configured to selectively remove a reactive gas from a flue gas stream using a catalyst and reagent to produce a scrubbed stream that is substantially depleted of the reactive gas. A heating device can advantageously be used upstream of the gas removal unit to thereby preheat the catalyst to an operational temperature and thereby reduce the start-up time of the process.

摘要： A lean solvent is produced from a CO2 rich solvent using heat exchange with a conditioned stream in a reboiler. A power generator generates a low pressure steam from high pressure steam. A portion of the low pressure steam is sent to a fluid conditioning unit, which conditions the low pressure steam to a temperature and pressure required to allow for the production of lean solvent from a rich solvent in a reboiler.

摘要： A system and method for treating flue gas that results from a combustion process is described. The method and system includes injecting an SOx absorbent reagent into the flue gas pathway at a point upstream of a selective catalytic reduction (SCR) reactor exit and downstream of a boiler exit. The method and system may also include injecting a NOx reducing agent simultaneously with the SOx absorbent reagent, either via the same injection system or via a second injection system located nearby the SOx absorbent reagent injection system. Injection of the SOx at a point upstream of the SCR reactor exit simplifies the injection systems, gas distribution systems, and physical and/or computational fluid dynamics modeling.
