Perilla oil drying oil similar to tung oil or linseed oil, perilla oil has been used for paints, varnishes, linoleum, printing ink, lacquers, and for protective waterproof coatings on cloth. Perilla oil can also be used for fuel. It is used along with synthetic resins in the production of varnishes. It dries faster than linseed oil and on drying forms a film that is harder and yellows more than that formed by linseed oil. The paint and varnish industry accounts for the largest usage. Perilla oil is also important in the manufacture of printing inks and linoleum, and in more ancient times
Oil production plant Sometimes the produced oil may be "stabilised" (a form of partial distillation) which reduces vapour pressure and sweetens "sour" crude oil by removal of hydrogen sulphide, thereby making the crude oil safer for storage and transport. The production plant is said to begin after the production wing valve on the oil well. The product from each well is piped through the choke valve, which regulates the rate of flow. The flowlines are gathered at the inlet manifold and routed into a separator, which will separate the three components. Once the oil has been separated from the gas and produced water,
