Vapor recovery units capture methane vapors given off by oil and condensate storage tanks as the oil resides in the tanks and pressure builds. In 2007, Hy-Bon was awarded several vapor recovery and flare reduction projects in countries like Angola, Libya, Venezuela, and the U.S., capturing anywhere from 25,000 to millions of cubic feet of methane vapors per day from offshore vent gas, wellhead gas, and casinghead gas flares.
