A vapor recovery unit (VRU) is an essential system for capturing and recovering valuable hydrocarbon vapors that naturally accumulate in crude oil or distillate storage tanks. These systems help operators comply with stringent emission regulations while reducing product loss and increasing operational efficiency.
VRUs are widely used across the oil and gas industry as well as in various process industries. Available in multiple configurations, they can be customized to suit a wide range of facility sizes and applications—from small field installations to complex processing plants.
How a Vapor Recovery Unit Works
The primary function of a vapor recovery unit is to extract vapors that collect inside sealed hydrocarbon tanks. Without a VRU, these vapors would either be vented into the atmosphere—contributing to emissions and loss of saleable product—or managed inefficiently.
A typical VRU process involves:
- Collection – Vapors are drawn from the tank’s vapor space.
- Separation – Gas is separated from any entrained hydrocarbons.
- Compression – The recovered gas is compressed to a usable pressure level.
- Discharge – Separated liquids are sent to storage, while compressed gas is redirected for use or sale.
This recovery process not only reduces emissions but also reclaims a valuable resource that would otherwise be wasted.
