Vohon Petrochemical designs and manufactures vapor recovery equipment for gas stations, tank farms and loading terminals — membrane separation technology that turns tank emissions into recovered liquid product and cleaner air.
We supply complete stage-3 vapor recovery systems that capture hydrocarbon vapors displaced from underground storage tanks during refueling and unloading — converting emissions into recovered liquid product.
Compact skid-mounted VRUs for retail gas stations, designed to handle vapors displaced during vehicle refueling and tanker unloading.
Compressor pressurization, air-cooled condensation and membrane separation recover hydrocarbon as liquid — engineered for gasoline station vapor loads.
Systems built around intrinsically safe electrical components and flameproof enclosures suitable for classified hazardous areas.
Treatment capacity, control logic and skid layout customized to local climate, site footprint and project specifications.
From technical proposal and installation guidance to commissioning support and spare parts supply for long service life.
Equipment engineered for overseas projects with attention to local technical specifications and regulatory requirements.
A typical stage-3 vapor recovery loop at a retail station.
Vapors displaced from underground storage tanks are collected through the tank venting and piping network.
Collected vapors pass through the recovery unit — adsorption beds, condenser or a hybrid train — separating hydrocarbon from air.
Recovered liquid hydrocarbon returns to the storage tank; concentrated vapors can be recycled into the process loop.
Lean exhaust air is discharged through a safe vent, meeting the project's emission design targets.
Our systems are sized for a range of hydrocarbon vapor sources.
Skid-mounted stage-3 VRUs that fit existing station layouts and handle refueling vapor loads with minimal footprint.
