Economic Analyses to Improve ROI

Invest in a new VRU to operate as the primary vapor control device at your terminal that currently uses a VCU. Vapor recovery technology offers the user a return on investment in the form of recovered product. Selling this recovered product that would otherwise be emitted into the atmosphere or burned in a combustion unit allows the user company to recoup its investment typically within the first one to three years of service.

Retrofit to Reduce Operating Costs


  • Retrofit your existing unit with dry vacuum pump technology to handle a wider range of vapors (including neat ethanol), simplify the vapor recovery process, significantly  reduce power consumption, and lower maintenance costs.
  • Retrofit your unit with a seal fluid temperature control valve to prevent rapid seal fluid  dilution with ethanol and save on seal fluid replacement costs.
  • Explore the possibility of retrofitting your existing system with a booster blower  package to substantially increase throughput for a lower capital cost.


  • Retrofit your older marine vapor combustion unit to reduce operating costs. Contact  a John Zink Hamworthy Combustion engineer to discover what upgrades can be made to your system that will reduce costs, increase capacity, and potentially expand the products you can handle with your existing unit.

Expertise to Meet GD GACT Rule


  • A retrofit for a continuous emissions monitoring system (CEMS) enables you to meet • the new GD GACT requirements, and can significantly reduce power consumption by using the CEM Start energy savings mode of operation. Power savings over conventional VRU logic are estimated at 30% – 50%, with a payback on investment often  within the first 1 – 2 years. If your VRU is already outfitted with a CEMS, contact us  to learn how the CEM Start mode can be incorporated into the logic of your system.
  • Contact a John Zink Hamworthy Combustion engineer to determine how to comply with GD GACT via para metric monitoring and recording in lieu of emissions measurement.
