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. Our VRU systems are available with Adsorption-Absorption (ADAB™) and Adsorption-Condensation (ADCON™) configurations, as well as varying vacuum technologies to best suit specific facility needs.
Our VRUs are designed to meet worldwide standards such as ASME, ANSI, DIN, ATEX, EN, NEC, IEC and CENELEC.
Our VRUs are configured in modular packages for greater flexibility.
Vapor recovery has many advantages when compared with vapor combustion technologies. For example, vapor recovery:
John Zink Hamworthy Combustion vapor recovery solutions have earned worldwide acceptance as the standard for evaporative hydrocarbon vapor control, offering:
Our vapor recovery technology can be applied to a variety of applications involving a wide variety of chemicals. Some of these chemicals are:
In typical installations such as truck, rail, tank and marine loading, our VRUs achieve emission control efficiencies of 99% or better. Most systems are designed to meet 1 – 10 milligrams of VOC released per liter of product loaded, or 1 – 10 grams per cubic meter of vapor vented. We have designed VRUs that meet stricter emissions standards including the TA Luft I standard of 150 milligrams of VOC released per normal cubic meter of vapor vented. We can also offer customized engineering evaluations and solutions to meet the TA Luft II standard.
Our ADAB vapor recovery design is suitable for a wide variety of applications. It is most commonly used to control hydrocarbon vapor emissions at terminals handling petroleum fuel products. Our VRUs combine physical adsorption with absorption to recover hydrocarbon vapors and return the recovered product to storage.
Dry vacuum pump (DVP) technology offers significant advantages over other vacuum technologies:
Liquid ring VRU systems operate along the same principles as dry systems, but with a liquid ring vacuum pump (LRVP) to regenerate the carbon beds. LRVPs have a proven history of successful operation and are available in a variety of configurations that can be tailored to fit your specific needs. In addition, we offer a specially formulated vacuum pump seal fluid — Z-SEAL™ — for use in this service.
Our Continuous Emissions Monitoring System typically yields around 50% in energy savings in the CEM Start mode of operation.
Our optional Continuous Emission Monitoring System (CEMS) includes an analyzer to measure hydrocarbon content in the VRU vent stream. The CEMS performs emission data averaging and can achieve VRU energy savings when utilizing the CEM Start mode of operation. The carbon beds are left on stream until their effective adsorption capacities have been expended before regeneration occurs. Typical energy savings using this mode of operation have averaged about 50%.
With VaporWatch™, engineers and maintenance personnel can securely access real-time online operating data directly from their computer, anywhere around the world. This remote access capability ultimately results in more efficient equipment operation, reduced downtime for loading terminal operations, and lower operating and maintenance costs.
With VaporWatch, you can monitor key system parameters and view real-time and historical data to identify trends.
This enhanced maintenance package records system data including pressures, temperatures, flows, and other vapor control parameters, and can be configured to output useful reports on system performance. Technicians can reference these reports to help diagnose and eliminate operational difficulties, predict equipment failures, and service equipment.
To keep you up and running during installation, retrofitting or maintenance, we offer equipment rental including the PECS® (Portable Emission Control System), a self-contained, trailer-mounted vapor combustor that ensures stable, smokeless combustion and maintains temperature control over a wide range of vapor combustion.
