Wellhead Vacuum

The Emmecom VCU series wellhead vacuum package is specifically designed to boost well head gas flow by reducing the flowing wellhead pressure. The liquid ring vacuum pump design offers the deep vacuum capability down to -90 Kpa (100 mbar absolute) and are ideally suited for “unconventional gas” applications such as enhancing the gas flow rate of low pressure wells, coal seam gas & land fill gas. 

The VCU series have a heavy duty structure that allows a greater differential pressure generation of up to 3 bar, and able to generate a discharge pressure of positive 2.5 bar depending on operating conditions. The package allows a negative pressure to be applied to the wells and can:

  • increase gas production for low pressure gas wells 

  • remove low pressure gas to aid in oil production 

The diagram below shows how the system could be set up.
