Patent ID: 7462331

Claim:
An oxidation-catalytic separation device for removing oil and volatile organic components from pressurized gases of a compression system, comprising a tank which contains an oxidation catalyst and through which the pressurized gas flows from an inflow side to an outflow side, wherein the tank includes at least two chambers with at least a first of the at least two chambers having a different diameter, a different length or a different diameter and a different length than a second of the at least two chambers, the first of the at least two chambers effecting aerosol separation and the second of the at least two chambers effecting a residual vapor catalysis, and wherein the at least two chambers are replaceable chamber-forming cartridge inserts, wherein a plurality of different chamber-forming inserts are provided for forming each of said at least two chambers, each of chamber-forming inserts having a different shape or size so that length and diameter ratios of the chambers can be varied by replacement of at least one of the chamber-forming cartridge inserts with another of the chamber-forming cartridge inserts of a different shape or size.
