An array of filters (53, 54, 73) installed within an enclosure, shell, or housing (40) into which a gas phase stream containing small concentrations of solids or particulates is introduced for purposes of separating the solids from the gas (22). Solids separation is accomplished by dry filtration when the gas (22) is forced by pressure through filter openings that are smaller than the size of the particulates. The filters (53, 54, 73) are constructed with apertures of micron and nanometer dimensions. |
