Vapor Control

2,000+ Installations.

Whether reducing emissions through the recovery of valuable product or the destruction of waste gas, our vapor control solutions simplify the process to make operations cleaner and more efficient. Our vapor control technologies have been designated as the “Best Demonstrated Technology” and the “Maximum Achievable Control Technology” by the U.S. Environmental Protection Agency.

Vapor Control Solutions

Vapor Combustion Systems

Superior, Field-Proven Performance.

Our VCUs can achieve volatile organic compound (VOC) destruction efficiencies greater than 99 percent, resulting in hydrocarbon emissions less than 10 milligrams per liter of product transferred. In addition, our VCUs satisfy all the applicable requirements of 40 CFR 60.18.

NOxSTAR Vapor Combustion

Proven Reliability With Low-NOx Performance.

Increasingly stringent NOx emissions regulations can put a strain on your operation. The NOxSTAR Vapor Combustion System, however, combines our proven burner technology with emissions control of less than 0.02 lbs NOx/MMBtu so you don’t have to sacrifice reliability to get the performance you need.

Vapor Recovery Systems

The Customized Solution.

Our Carbon Adsorption Vapor Recovery Units (VRUs) safely prevent harmful volatile organic compounds (VOCs) from being released into the atmosphere during operations that involve the transfer of evaporative hydrocarbons. Because our VRUs are highly adaptable for a variety of applications, our engineers can customize an emission control solution that optimizes your specific system.

PureWorx SVT

Another JZHC Innovation.

After introducing rotary screw dry vacuum pump technology and installing more than 150 worldwide, we’ve introduced the latest dry vacuum pump innovation for VRUs: PureWorx SVT (Sliding Vane Technology). PureWorx SVT is an alternative solution to liquid ring technology that is more compatible with gasoline additives such as ethanol and reduces power consumption, waste disposal, and system complexity.

Crude Oil Vapor Recovery

Recapture Product, Recover Profit.

Crude oil loading operations present many technical challenges for a vapor recovery system. We’ve developed a system that can cost-effectively recover vapor from crude and other light semi-refined products. Reducing emissions. Eliminating NOx. And recapturing cash.
