EJECTORS
WHAT IS AN EJECTOR?
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
