EJECTORS

WHAT IS AN EJECTOR?

Ejector - Diagram.jpg

Ejectors use the energy of a high pressure fluid to entrain and compress a low pressure fluid.

Ejectors are also known as ‘Eductors’, ‘Surface Jet Pumps’ or ‘Velocity Spools’.

Ejectors Are Compressors!

  • No moving parts

  • Zero maintenance

  • Often utilize ‘waste’ energy

  • Fast-track project time

  • Do not trip or fail

  • Light & compact

  • Zero emissions

  • Universal Design

GAS DRIVEN EJECTORS

Typical Gas Compression Applications

  • Flare and Flash Gas Recovery

  • CO2 Gas compression (CCUS)

  • Hydrogen compression

  • Associated gas compression

  • Stranded gas recovery

  • Gas gathering stations flow boosting

  • Increasing capacity of existing compressors (becomes another stage)

  • Replacing existing compressors

  • De-bottlenecking existing compressor trains

  • Process gas compression

  • Direct gas injection into wells (SWAG)

  • Coke Oven Gas Compression / Recovery

LIQUID DRIVEN EJECTORS

Typical Applications for Produced Water
& Sand Management

 

  • Pressure boosting after hydrocyclones

  • Slurry pumping as part of a solids handling / separation system

  • Flow boosting for separator flushing applications

  • Desanding for gas flotation units or desanders

  • Sand cleaning / scrubbing

  • Flushing slurry lines following sand removal

ADVANTAGES OF EJECTORS FOR ENHANCED RECOVERY

  • No operating costs

  • No maintenance costs

  • No carbon footprint

  • Low weight & compact size

  • Low project costs (when compared to traditional compressors)

  • Fast-track installation available for short-term well opportunities

  • Minimal disruption to existing production      operations

  • Ideal solution for topside, subsea or FPSO       installations

TANK JET MIXERS

  • No moving parts inside the tank  

  • Virtually maintenance free once installed

  • Quick mixing times (3-Parts Suction within the tan to every 1-Part Motive fluid)

  • Custom designed to suit specific fluid properties   and Tank geometry

  • Suitable for suspension of solids and mixing sludges

  • No limitation on tank size, multiple mixers can be installed

  • Can be ‘through-the-wall’ designs, so no access   required for installation

  • Fast-track design, manufacture and deployment available
