Abstract:
1. A knitted wire mesh mist collector pad having an average density (measured in terms of mass per volume of the knitted wire mesh collector pad) and comprising at least three zones of flattened and crimped wire mesh tube, at least two of said zones having densities (measured in terms of mass per volume of the knitted wire mesh in each of said at least two zones) that are different from one another as a result of comprising meshes of different densities (measured in terms of mass per volume of the knitted wire mesh) and the at least three zones arranged so that a density gradient in the direction of gas flow through the pad varies from low density to high density to low density and comprising: (a) a first zone of the mist collector pad including one or more stacked layers of a knitted wire mesh tube that has been (i) flattened and (ii) crimped twice; (b) a second zone of the mist collector pad including one or more stacked layers of a knitted wire mesh tube that has been (i) flattened and (ii) crimped once; (c) a third zone of the mist collector pad including one or more stacked layers of a knitted wire mesh tube that has been (i) flattened and (ii) crimped twice; (d) the first, second, and third zones secured in a grid which is used to install the mist collector pad in a process gas stream so that during use of the mist collector pad, the first zone is upstream of the second zone and the second zone is upstream of the third zone; and wherein:
