Finishing oil linen or cotton fabrics with the boiled oil. Tung oil is pressed from the nuts of the tung tree. Raw tung cures better than raw linseed and so it is often used in this form. As tung oil yellows with age less than linseed, it is favoured for high quality and furniture work. Most modern finishing oils use a blend of oil and a thinning agent such as white spirit. Raw oils tend to be applied too thickly, leading to a thick layer that cannot cure effectively and so remains sticky. A thinned oil is easier and more reliable to
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
