    摘要： A system for treating a flue gas includes a first condensing heat exchanger located in the housing for removing heat from flue gas as the flue gas is downwardly passed therethrough. A first collection tank is located in the housing below the first heat exchanger for collecting liquid and particulate. A second heat exchanger is located in the housing for condensibly removing pollutants from the flue gas as the flue gas is upwardly passed through the second heat exchanger. A second collection tank is located in the housing below the second heat exchanger for collecting liquid and particulate.

    摘要： An asymmetrical, or non-uniform arrangement of heat exchanging tubes in a second stage heat exchanger of an integrated flue gas treatment system provides improved flow characteristics and reduces or eliminates flooding caused by the counter-flow of upwardly rising flue gases and downwardly falling reagent and condensate through the heat exchanging tubes. The non-uniform spacing produces a non-uniform velocity profile with at least one low velocity region in each row, allowing reagent and condensate to drain downward at said low velocity region, thereby preventing high gas phase pressure drop caused by the onset of flooding. Embodiments are provided in which one of every six tubes are removed from each row in a uniform array of tubes, or one of every four tubes are removed from each row in a uniform array of tubes. Other asymmetrical, or non-uniform spacings are possible.

    摘要： A two-stage downflow flue gas treatment condensing heat exchanger system allows for flue gas to be passed into a two-stage housing at an upper end of the housing. The flue gas is channeled through a first stage of the housing having a first condensing heat exchanger which cools the flue gas. The flue gas is then channeled through a second stage having a second condensing heat exchanger which is located directly beneath the first stage and the first condensing heat exchanger for further cooling the flue gas. The flue gas travels in a downward direction only through the housing and exits the housing at the lower end of the housing beneath the second stage. A collection tank is located beneath the second stage of the housing for collecting liquids, condensate, particulate and reaction product.

    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.
