Vapor Recovery

Transforming waste vapor into sustainable energy

Vapor recovery for hazardous air pollutant (HAP) emissions is a critical and mandatory process for industrial operations across the energy sector. Audubon addresses routine flaring and Environmental Protection Agency (EPA) emission regulations with an unprecedented, turnkey solution for vapor recovery that converts your facility’s waste stream into power or heat energy.

Vapor Upcycle System

Achieve vapor recovery, regulatory compliance, & sustainable energy at once

The EPA’s updated standards for gasoline distribution are stricter than ever and apply widely across energy and industrial logistics and operations. As part of our full portfolio of engineering, procurement, and construction (EPC) services, Audubon delivers compliance with the National Emission Standards for Hazardous Air Pollutants (NESHAP) and New Source Performance Standards (NSPS) with our patented Vapor Upcycle System (VUS).* The proprietary VUS captures waste vapor with industry-leading destruction efficiency—and then reuses it as an energy source for power generation, electrical grid support, or renewable feedstock. Using combined heat and power (CHP) technology and an energy-saving modular design, the VUS revolutionizes the vapor recovery process, making it far more efficient and sustainable than traditional methods of recovery and combustion. Operators can harness their waste vapor as reuseable energy while saving time and cost in startup, operations, and maintenance.
