Gas Jet Compressor Systems for Gas Fields

Gas jet compressor systems for the exploitation of gas fields. GEA designs, manufactures and delivers gas jet compressor systems for on- and offshore applications consisting of jet pumps (ejector or eductor) and silencers to reduce the sound pressure level.

Why an ejector system is needed
- Natural gas is available with up to 600 bar pressure at a newly drilled well.
- The natural gas can be conveyed directly through pipelines for further processing or to place of use.
- Available gas pressure reduces with time, so mechanical compressors are required.
- Mechanical compressors are working within their flow/pressure diagram; as the suction pressure becomes lower, the suction flow lowers.
- To improve/increase the flow of the compressor, an ejector can be installed to boost the suction gas to a higher pressure level.
- Result is extending the economic life of the gas field

Example: Gas jet compressor system with jet pumps 8” / 16” / 16” (motive/suction/discharge) with a total length of about 4.5 m and silencers to reduce the sound pressure level. The unit compresses a low-pressure natural gas (about 8 barg) by using a high-pressure natural gas (>90 barg) to an intermediate gas pressure (about 12 barg) and is designed to support the installed mechanical main compressor stage.

The ejector-body is designed for 137 barg — the motive side for 213 barg. Material of construction is corrosion-resistant and corrosion-tested Duplex-stainless steel, which is coated with sprayed Aluminum.

GEA MDI Splitting Process

Methylene diphenyl diisocyanate (MDI) is an organic chemical which is one of the main components for the production of polyurethanes. Crude MDI is still only commercially produced via the phosgene route and contains three diisocyanate isomers, oligomeric polyisocyanates (tri,tetra,penta ,etc isocyanates), ...
Jet Pumps, Mixers, Heaters and Vacuum Systems

Jet pumps, also referred to as ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids in which a gaseous or liquid medium serves as the motive force. They operate by the conversion of pressure energy into velocity in suitable nozzles. They are “pumps without ...
Jet Mixer Systems

Applications. Liquid jet mixers are jet pumps to mix and circulate liquids. The range of applications for liquid jet mixers is only limited by the viscosity of the liquid to be mixed. As a rule, jet mixers can be used in all cases where the liquid to be mixed can still be supplied by a centrifugal pump. ...
Steam Jet Vacuum Pumps

Jet vacuum pumps are used to create and maintain the vacuum in evaporators, driers, in distillation and rectification plants, and in the processes of freeze drying, polycondensation, degassing and deodorizing. These sorts of equipment consist fundamentally of jet pumps and condensers or of a combination ...
