Abstract
A system of conditioning elements is described for supply of conditioned seal gas to the seal chamber of a rotary machine employing gas lubricated, non-contacting seals. It includes elements to remove particulate solid and liquid and volatile components from the gas and to heat the gas to a predetermined level. It also includes an element to amplify the pressure of the gas. The pressure amplifier is operative in response to a condition of the gas to be supplied to the seal chamber, to ensure that an adequate supply of seal gas is available. The system of conditioning elements may be assembled onto a single skid.
