Gas Seals: Versatile Non-Contact Sealing Solutions for Compressors and Turbomachinery

Gas seals are mechanical seals which utilize the controlled operation of a controlled gas film to separate the sealed machine's and stationary machine's wear surfaces and thus maintain clean low wear seals at high speeds. There are many different variations of the gas seal family to meet specific process and safety specifications. Gas seals have found their strongest applications in compressors, turbines and gas handling process equipment where the principal emphasis is on low maintenance requirements, clean seal areas and high operational efficiency.

Advantages of Gas Seals

Non-contacting

The non-contacting operation of dry gas seals greatly reduces the mechanical wear of dry gas seals and extends the time between maintenance visits, compared to many other types of sealing devices.

Minimal leakage

Due to the finely engineered geometries of the sealing surfaces and the precise volume of sealing gas supplied to the seal, dry gas seals have very low leakage rates.

No contamination

There is no risk of contamination with dry gas seals, because dry gas seals only use gas to create a division between the sealing surfaces.

Application Gas Seals

When equipment cannot be lubricated by the application of a liquid and high rotational speeds or process purity are crucial the following are typical application examples include:

Refining and Petrochemical Plants

Centrifugal compressors compress process gases such as cracked gas, hydrogen or natural gas where seal environments must be clean and dry.

Natural Gas Transmission and Processing

Pipeline booster compressors or gas treatment installations utilise the properties of reliable non-contact sealing.

Production of Industrial Gases

Compressors that produce Nitrogen, Oxygen, and specialist gases require prohibiting contamination of process gases.

Energy and Power generation

Auxiliary gas turbine compressors or High-Speed Rotors necessitate the maintenance of stable, frictionless seals.

FAQ

How is a dry gas seal defined?

A dry gas seal is an engineering device that prevents wear and friction by utilizing a gas barrier between moving components.

Where is it common to find dry gas seals?

Typically, dry gas seals are found in electric or diesel powered centrifugal turbine machines and in an array of other applications, including petrochemical industry machinery.

In what ways do dry gas seals differ from oil lubricated seals?

Unlike oil lubricated seals, which use liquid lubricants to lubricate the seal contact area, dry gas seals achieve stable gas pressure with the seals' grooves, which create a stable gas film around the inner surfaces of the seal.
