The Pursuit of Ultra-Low Emissions

Recovery of hydrocarbon vapours and compliance with environmental and safety regulations that are set by environmental authorities are key factors for refineries, petrochemical plants, tank storage, LNG terminals, and other facilities.
The storage of hydrocarbon products, as well as their transfer to carriers and vice versa, is often associated with the formation of vapours, whose composition is a mixture of atmospheric air and volatile organic compounds (VOCs).
To comply with environmental regulations, the vapours need to be treated in a vapour recovery unit (VRU) and, for the most stringent regulations, in a further oxidisation stage, which is commonly conducted through the use of vapour combustion units (VCUs) and thermal oxidisers.
