VRUs

Beyond the core components, a vapour recovery unit package is only as reliable as the integration of those components. Piping design, elevation data, and liquid handling theories all influence long-term performance. Poorly sloped piping or insufficient drain points can allow liquids to accumulate upstream of the compressor, increasing the risk of slugging and mechanical damage. For that reason, VRU packages are often designed with deliberate piping geometry and dedicated liqu

VRUs address ongoing issues with tank vapours in industrial systems. Tank vapours are volatile organic compounds (VOCs) released from liquids stored in tanks, such as fuel or oil. They are a product loss, an emissions risk, and, in many cases, a compliance issue. A vapour recovery unit , often shortened to VRU , is designed to capture harmful vapours that would otherwise vent to the atmosphere and compress them for reuse. The U.S. EPA  describes VRU operation as "pulling hyd
