There are a large crude oil storage tanks in the Oil fields.
These tanks are used to hold oil for brief periods of time
in order to stabilize flow between production wells and
pipeline or trucking transportation sites.
During storage, light hydrocarbons dissolved in the crude
oil including methane and other volatile organic compounds
(VOC), natural gas liquids (NGLs), hazardous air pollutants
(HAP), and some inert gases vaporize or "flash out" and
collect in the space between the liquid and the fixed roof
of the tank. As the liquid level in the tank fluctuates,
these vapors are often vented to the atmosphere. One way to
prevent emissions of these light hydrocarbon vapors and
yield significant economic savings is to install vapor
recovery units (VRUs) on oil storage tanks. VRUs are
relatively simple systems that can capture about 95 percent
of the Btu-rich vapors for sale or for use onsite as fuel.
NRG Global Power will be investing in the flared gas
recovery in Libya and the world, by supplying new units ,
rentals and long leases to potential partners.
