    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： A scoop is used to collect a liquid slurry upstream of an internal collection tank. The scoop is in fluid communication with a downcomer, which receives at least part of the collected slurry, thereby maintaining a continuous flow of liquid slurry through the scoop to prevent plugging. Collected slurry can be removed for treatment from the scoop or the downcomer. In an application to a wet flue gas desulfurization (FGD) scrubber, the scoop collects an effluent slurry of partially reacted liquid scrubbing reagent and scrubbing byproducts before they drain into an internal reaction tank. Partially reacted liquid scrubbing reagent and scrubbing byproducts can therefore be withdrawn for treatment before the addition of fresh reagent alters the pH of the treatment stream.

    摘要： A two-stage flue gas treatment condensing heat exchanger system allows for flue gas to be passed into a two-stage housing at an inlet of the housing. The flue gas is channeled downwardly through a first stage of the housing having a first condensing heat exchanger which cools the flue gas. The flue gas is then upwardly channeled in the housing through a second stage having a second condensing heat exchanger which is located near an outlet. A collection section is located between the first stage and the second stage of the housing for collecting liquids, condensate, particulate and reaction product. Steam is injected into the housing at a plurality of locations for enhancing particulate removal.

    摘要： 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 CO2 absorber, 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 CO2 absorber 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.

    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.
