Unique, Patented Natural Gas Compression Technology for Driving Down Emissions

Use Case: Pipeline Evacuation and Natural Gas Recovery with the GoVAC® MAX System

by

Challenge

Faced with the need to perform scheduled integrity digs on a 26,400-foot section of 12-inch pipeline, a leading U.S. natural gas utility took a forward-thinking approach to environmental responsibility. The utility sought a solution that aligned with its commitment to sustainability, safety, and operational excellence. Their goal: to recover natural gas efficiently while minimizing environmental impact and ensuring regulatory compliance.

Solution

ZENRG Services, an authorized service provider for Onboard Dynamics, deployed two GoVAC® MAX Systems to perform the evacuation. The systems successfully cross-compressed the natural gas in under seven hours, eliminating methane emissions during the process. Integrated automated data capture enabled remote monitoring and delivered accurate, real-time operational reporting—ensuring transparency, traceability, and compliance throughout the project.

The successful deployment of the GoVAC® MAX System in the Southern US project demonstrates the powerful intersection of innovation, environmental stewardship, and operational efficiency. By capturing and recovering over 274,000 SCF of natural gas and avoiding more than 158 metric tons of CO₂e emissions, this project exemplifies how advanced evacuation technology can transform routine pipeline maintenance into a model of sustainability and accountability. The GoVAC® System not only supports regulatory compliance and ESG goals but also delivers measurable value through data-driven performance and reduced environmental impact—setting a new standard for responsible energy infrastructure management.
