Compressor Dry Gas Seal

Compressor Dry Gas Seal: Optimized Sealing Performance for Modern Process Gas Compressors

An example of a specific usage for a compressor dry gas seal is a centrifugal compressor or process gas compressor. A compressor dry gas seal integrates dry sealing gases creating a stable interface that minimizes any chance of leakage thereby making compressors operate efficiently. Dry gas seals continue to maintain their reliability in applications with high volumes of natural gas, chemical gases and other process media. The non-contact dry gas seal operating aspect provides longer service life and consistent performance of the compressor regardless of the operating loads placed on it.

Advantages of Compressor Dry Gas Seal

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 Compressor Dry Gas Seal

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.
