Volatile Organic Compounds (VOCs) 08
Volatile Organic Compounds (VOCs) 08 : Chemistry and Chemical Disasters. A mixture of propane, butane and several other gases given off through the vaporization of crude oil and refined products, such as petrol. VOCs are usually divided into non-methane (nmVOCs) and methane. As soon as petroleum is handled in the open air, vapours escape unless something is done to contain them. These hydrocarbons in gaseous form can be emitted into the atmosphere from platforms (extraction of oil), tankers (transportation of oil), terminals (loading and unloading of oil), filling stations (petrol tanking) refineries (processing of oil), pipelines (leakages of oil), and aircraft ( fuel dumping). Hydrocarbon vapours can be recovered and "recycled" as liquid fuel. They are collected and condensed when petroleum products are being loaded and unloaded at terminals, refineries and petrol stations
