APPARATUS FOR REMOVING FINELY DIVIDED SOLIDS FROM GAS Abstract of the Disclosure Apparatus for separating finely divided solids from gas is described comprising a generally cylindrical vessel having a gas inlet opening and a gas outlet opening, a solids inlet opening at the top of the vessel and a solids outlet opening at the bottom of the vessel. First generally cylindrical wall member having a diameter less than that of the vessel is disposed in the vessel to provide an elongated annular space lying between it and the vessel wall. The first cylindrical wall member is in sealing engagement with the top portion of the vessel. A second generally cylindrical wall member having a diameter less than the first wall member is disposed inside the first wall member to provide an elongated annular space between the two wall members which space is filled with a solid particulate contact material and which moves by gravity flow downwardly through the annular space. The surfaces of both cylindrical wall members are louvered surfaces formed by perforating the walls to form louver vanes inclined to the vertical at an angle of about 15 to 80 degrees and having louver openings suffi- ciently large that most of the particles constituting the contact mass are capable of passing through the openings. The louver vanes of the first cylindrical wall member extend outwardly and those of the second wall member extend inwardly. Means for controlling the flow of the solid contact material through the louver openings to restrict the flow to a minor proportion of the total contact material and means for facilitating passage of the overflow contact material through a solids outlet opening in the bottom of the vessel are provided.
