Oil paint produce refined varieties of oil with fewer impurities, but many artists prefer cold-pressed oils. Other vegetable oils such as hemp, poppy seed, walnut, sunflower, safflower, and soybean oils may be used as alternatives to linseed oil for a variety of reasons. For example, safflower and poppy oils are paler than linseed oil and allow for more vibrant whites straight from the tube. Once the oil is extracted, additives are sometimes used to modify its chemical properties. In this way, the paint can be made to dry more quickly (if that is desired), or to have varying levels of gloss, like
Oil production plant Oil production plant An oil production plant (sometimes called an oil terminal) is a facility which performs processing of production fluids from oil wells in order to separate out key components and prepare them for export. This is distinct from an oil depot, which does not have processing facilities. Typical production fluids are a mixture of oil, gas and produced water. Many permanent offshore platforms have full oil production facilities on board. Smaller platforms and subsea wells must export raw production fluid to the nearest production facility, which may be on a nearby offshore processing platform or an onshore terminal.
