François Negroni, ALMA Group, outlines the benefits of using a standardised vapour recovery unit to handle emissions.

vapour recovery unit (VRU) is an engineered industrial system dedicated to downstream petroleum storage and transfer activities. Before loading new hydrocarbons, trucks need to unload volatile organic compounds (VOCs) out of the tank. A VRU is the only clean solution to handle VOC emissions generated during day-to-day operations. Alternative options are to release directly into the atmosphere via a vent or to burn the system via a flare

advanced stack, both of which are not environmentally friendly. However, VRUs are a highly-specialised field that require specified knowledge. Poor maintenance of a unit can lead to emission problems, safety complications, operational problems and financial inefficiencies. The capture and recovery of hydrocarbon vapours to reduce emissions of environmentally hazardous VOCs is a vital concern in modern oil and gas production and
