Tung oil tung oil is the only drying oil that will polymerize 100% (completely harden). Linseed oil, for example, never completely hardens. Since tung oil has become popular as an environmentally friendly wood finish, some products labelled as "tung oil" are actually blends containing other oils, varnishes, solvents, or chemical driers, and may even containing no tung oil at all Products labeled "Danish oil" may be tung oil or they may be polymerized linseed oil. The product packaging will usually clearly state if it is pure tung oil. Heating tung oil to about in an oxygen-free environment will substantially increase the viscosity
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
