compression of natural gas

Frequently Asked Questions

• WHAT IS CROSS COMPRESSION?

  Instead of releasing methane gas into the atmosphere by venting, Versiv’s innovative cross compression solution uses specialized equipment to evacuate natural gas out of a section required to be depressurized and recycle it back into another section of the system. This process allows us to minimize the impact of methane released into atmosphere.

• WHY DOES CROSS COMPRESSION HELP THE ENVIRONMENT?

  With Versiv’s cross compression solution, we can safely control the transfer rate of methane capture from an isolated area of pipeline through pressurize systems. This allows pipeline owners to recover gas and transfer it at a constant rate, no matter the pressure differential. Our solution speeds up the gas recapture process, allowing customers to meet ESG methane emissions reduction goals – safely, efficiently, and reliably.

• WHO SHOULD USE CROSS COMPRESSION?

  Operators who want to eliminate the need for voluntary natural gas flaring or venting associated with blowdowns during pipeline operations should use Versiv’s cross compression solution.

• HOW LONG DOES CROSS COMPRESSION TAKE TO COMPLETE?

  While time may vary depending on the location and complexity of the project, Versiv’s cross compression solution is rapid and offers minimal disruption to pipeline operations. Completed projects to date have ranged from 5 minutes to several days from start to completion.

• Why should we partner with Versiv?

  We are a nation-wide provider – leveraging the Artera footprint across 41 states and 130+ locations. Our scale differentiates us, allowing Versiv to be responsive and cost effective.

• WHAT ARE THE OTHER NAMES FOR CROSS COMPRESSION?

  Cross compression is also known by several other names, reflecting its various applications and benefits in the natural gas industry. These include “Greenhouse Gas Capture,” “Recycle Gas,” “Emissions Reduction,” “Venting Recovery,” “Recompression,” “Natural Gas Sustainability,” “Temporary Compression,” “Mobile Compression,” “Portable Compression,” and “Pipeline Evacuation.” Each of these terms highlights a specific aspect or use of cross compression technology in enhancing the efficiency and environmental sustainability of natural gas operations. Read our blog about the various names here. 

• WHAT IS THE COMPRESSION PROCESS OF NATURAL GAS?

  Venting natural gas during a pipeline blowdown prior to conducting repairs or retiring a pipe can be avoided by using cross compression equipment and procedures. A cross compression system recovers the gas that would have been vented to the atmosphere by compressing the gas in the isolated section of pipe and transfers it to a different section of the pipeline, another nearby pipeline, or storage location.

   

  The “purge” line is the pipe section from which natural gas is being removed from, and the “pack” line is the pipe section that the natural gas is being injected into. Once compressed, the gas can be transferred to a different section of the pipeline, a nearby pipeline or, if a nearby pipeline is not available, the gas can be transferred to a storage vessel to be transported to a different location, also known as methane recapture.

• WHAT TYPES OF ENVIRONMENTS CAN CROSS COMPRESSION BE PERFORMED IN?

  Cross compression is a safe and versatile process that can be deployed in a wide range of environments or communities. With various equipment options custom to different applications, we have successfully deployed Cross Compression in rural areas, near airports, energy power plants, busy highways, residential neighborhoods, within municipal communities, alongside busy roads/highways, and near schools and businesses.
