ZEVAC Ventless Purge on a New Pipeline
See how ZEVAC cross compression purged a five mile section of new construction pipeline without venting. Using compressed air as a vacuum, the pipeline was cleared and feed gas was introduced into the system the next day.

Instead of releasing gas to the atmosphere, ZEVAC helps utilities safely capture and manage natural gas in pipelines. The pneumatic (air) powered and controlled technology eliminates the noise, permits, notifications, hazards, and difficulties of venting and flaring.
ABOUT ZEVAC
From mobile gas evacuation units to fully customized equipment and field services, ZEVAC enables a closed-loop system of capturing, transferring, and reusing natural gas during pipeline operations. The methane mitigation equipment reduces product loss, minimizes costly service calls, and supports safer, more efficient maintenance across the gas distribution network.
Since 1952, Kerr Engineered Sales Company has represented leading pipeline and performance equipment manufacturers across the Eastern U.S. With four generations of family leadership, Kerr continues to serve the industry with the same commitment to quality, reliability, and personal service that has defined our company for more than 74 years.
GPT EVOLUTION INSTALL USES ZEVAC
A gas operator installing an 8in GPT EVOLUTION isolation gasket utilized ZEVAC to capture and recover vented gas. This made the operation emission free.

Isolation gaskets are installed to protect lines from corrosion and unintentional leaks. Inmost cases, installing these gaskets requires sections of pipelines to be evacuated and purged, often by gas venting. The practice of venting creates intentional natural gas emissions, releasing methane into the atmosphere. It is a paradox to vent while protecting against leaks.
A gas pipeline operator in Pennsylvania needed to install an 8in GPT Evolution Isolation gasket at a well pad north of Pittsburgh. Instead of venting before installing and releasing emissions into the environment, they utilized ZEVAC services to capture and recover the vented gas. To draw down 200ft of 8in line from approximately 200 psi down to zero with ZEVAC took approximately one hour from set up to the point when the gas in the section had been re-compressed into an adjacent line.
Company personnel were then able to install the GPT EVOLUTION gasket. This gasket is fully encapsulated and just 1/8in thick for easy installation. The GPT EVOLUTION is extremely abrasion and impact resistant due to the proprietary coating. It is also fire safe and does not have lamination.
This project protected their pipeline and protected the environment.
