Linseed oil unusually large amount of α-linolenic acid, which has a distinctive reaction with oxygen in air. Specifically, the fatty acids in a typical linseed oil are of the following types: Having a high content of di- and tri-unsaturated esters, linseed oil is particularly susceptible to polymerization reactions upon exposure to oxygen in air. This polymerization, which is called 'drying', results in the rigidification of the material. The drying process can be so exothermic as to pose a fire hazard under certain circumstances. To prevent premature drying, linseed oil-based products (oil paints, putty) should be stored in airtight containers. Like some other
Gas oil separation plant Gas oil separation plant A Gas-oil separation package (GOSP) is a "package" used in the upstream oil industry. The package is fitted the well head after the choke valve and before the production manifold, and separates the crude oil from sediments, solids and sand (below using a filter) and gases and condensates to allow the crude to be pumped on the pipeline. Beware that water need not be separated, causing the need to add chemicals so that the crude and water emulsifies. This process is then reversed at storage by adding demulsifiers that makes the water fall out, and can
