Mobile Compression: Gas turbine is successful evacuating natural gas pipeline

About 90% of natural gas previously vented to the atmosphere is recoverable.
More About Vericor's ASE50B

The Challenge

Recover up to 90% of natural gas in pipeline section without venting.

Vericor's Solution

A 5,000 shp gas turbine driven compressor to evacuate and bypass the gas around a maintenance location.

The Results

  • Reliable pulldown operation with follow-on order.
  • About 90% of natural gas previously vented is recoverable.


The Vericor ASE50B has been deployed for 5 years in a mobile pull-down compressor trailer, and the previous ASE40 is still operating in the same application for over 40 years. These are owned and operated by a major North American pipeline company for natural gas pipeline maintenance.

The ASE50B engine is direct cantilevered- mounted from a centrifugal compressor on a single drop-down heavy-duty trailer and housed in a sound attenuated enclosure with a full set of auxiliary support systems. This mobile trailer is able to access natural gas pipelines in remote areas and in the harshest climates. The trailer is utilized across multiple stations to evacuate natural gas out of pipeline segments that are scheduled for maintenance.

The ASE50B gas turbine is compact and versatile. Start time from stop to full power is achievable in under one minute.

The ASE50B gas turbines are a proven aero-derivative design that are specifically configured for power generation and compressor driven applications.

    Case Study details and the benefit of an aero-derivative gas turbine

    Now powered by an ASE50B, a new additional power-packed trailer evacuates pipelines for maintenance by transferring gas downstream to high pressure pipe sections exceeding pressures of 80 bar. The centrifugal compressor provides high volumetric efficiency. No external electricity is needed for the trailer’s black start capability power, ramped up quickly with an internal auxiliary power generator to turn the gas turbine starter.
