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.

A system of gas conditioning elements for supply of seal gas to the seal chamber of a rotary machine employing at least one gas lubricated, non-contacting seal comprising:
- conduit defining a fluid path and having;
- a connection adapted to be connected to a source of gas to be supplied to the seal chamber;
- a connection adapted to be connected to the seal chamber;
- a knock-out filter to remove solid and free liquid particles and a coalescer to remove aerosols from the gas connected to said conduit in said fluid path between said connections.
A system for supply of seal gas to the seal chamber of a rotary machine employing at least one gas lubricated, non-contacting seal comprising:
- a seal gas pressure amplifier connected between a source of gas to be supplied to the seal chamber and a connection adapted to be connected to the seal chamber, said pressure amplifier including a drive element and a gas compression element;
- a sensing mechanism adapted to sense a condition of the seal gas to be supplied to the seal chamber;
- a control mechanism connected to control operation of said drive element, and
- circuitry connected between said sensing mechanism and said control mechanism such that said control mechanism responsive to the sensed condition of the gas to be supplied to the seal chamber.
A system for supply of seal gas to the seal chamber of a rotary machine employing at least one gas lubricated, non-contacting seal comprising:
- a first source of gas to be supplied to the seal chamber connected through said system to a connection adapted to be connected to the seal chamber;
- a second source of gas to be supplied to the seal chamber;
- a seal gas pressure amplifier connected to said second source of gas and through said system to said connection adapted to be connected to the seal chamber;
- said pressure amplifier including a drive element and a gas compression element connected thereto;
- a sensing mechanism adapted to sense a condition of the seal gas to be supplied to the seal chamber;
- a control mechanism to control operation of said drive element, and
- circuitry connected between said sensing mechanism and said control mechanism such that said control mechanism is controlled in response to the sensed condition of the gas to be supplied to the seal chamber.
