Hydrocarbon vapour control for tank farms, loading terminals & distribution facilities
The LINESIG Vapour Recovery Unit (VRU) is an engineered industrial system for collecting and treating fuel vapours displaced from road tanker, railcar, marine loading and storage operations. It is designed to reduce uncontrolled volatile organic compound (VOC) emissions while enabling recovery of reusable hydrocarbon product where technically and economically feasible.
LINESIG vapour recovery systems are engineered to capture and recover volatile hydrocarbon vapours released during fuel storage, transfer and loading operations. The systems can combine vapour collection, conditioning, adsorption or condensation, vapour recovery and automated controls in a packaged solution tailored to fuel properties, operating cycles and required emission limits.
For multi-tanker gantry systems, vapour from individual loading bays is routed through a common vapour-return header to a centralized recovery package, allowing the VRU to operate as an integrated part of the loading rack with batch, ESD and terminal automation interfaces.
Typical vapours / service media
Gasoline / motor spirit vapours; light petroleum and hydrocarbon solvent vapours; naphtha and compatible volatile liquid vapours; other VOC-bearing streams subject to compatibility assessment. Diesel, kerosene, jet fuel and heavier products may produce lower vapour loads, but applicability and recoverability must be confirmed for the operating conditions.
Important: VRU suitability depends on vapour composition, water content, oxygen content, contamination, temperature and flammability limits. Highly reactive, corrosive, polymerizing or incompatible streams require special engineering.
