Mobile Gas Ejector Package

A package that entrains low-pressure gas into a higher-pressure stream using the energy of a motive fluid.

Purpose

Recover low-pressure gas, reduce flaring and use an available pressure differential without a separate mechanical compressor.

The gas-gas configuration uses higher-pressure motive gas. The liquid-gas configuration circulates motive liquid through a pump, ejector and separator. Low-pressure gas enters the ejector in both arrangements.
