Patent ID: 7766996

Claim:
A method of canceling pressure pulsations from operating blowers in a gas separation plant comprising: a) installing two identical blowers, each having an intake flange, an intake side, a discharge side, a discharge flange and a centerline between the intake side and the discharge side; b) connecting the first blower to a first conduit at either the discharge flange or the intake flange and the second blower to a second conduit at either the discharge flange or the intake flange; c) positioning the first conduit and second conduit symmetrically; d) merging the first conduit with the second conduit at a merging point into a single merged conduit; and e) synchronizing the first blower with the second blower, wherein the first blower generates pressure pulsations at a targeted frequency that are 180° out of phase with the pressure pulsations at the same targeted frequency generated by the second blower.
