In the pretreatment process, through filtering or catalytic removal of streaky oil contained in raw materials such as metal foreign bodies and sodium, potassium, phosphorus impurities. According to Korean bioenergy association, will be subject to 2017, the battery supplies of oil, cattle bone soup and pig production process of oil and other animal oils, in biological heavy oil raw material proportion is only 3. 7%. So far, streaky oil in heavy oil raw material proportion of also is very small. Biological heavy oil in pigs, cattle, chickens and so on animal oil supplies of oil from the oil, battery hotel or home of waste cooking oil, etc. , as raw material, made of. Recently, the chuck can produce pollution to the environment of the supplies of oil, to a biological heavy oil, can make a generator of coal-fired power plants, which has attracted much attention. In the mixing process, after each working procedure of raw materials will be mixed according to quality standards. Like oil products, how much solar energy mix water valve henan wind power projects without extraction, distillation process, but through the flow chart of pretreatment, heat exchanger station processing, mixing process, for production. In Korea, when eating roast pork belly, always beside the pan put paper cups, collecting supplies of oil, so the collection of oil are gone? However, as the coal-fired power plant in South Korea to promote biological heavy oil, using heavy oil producing capacity is expected to rise further, also have great help to environmental protection. South Korea is the world's first biological heavy oil as oil alternative fuel, coal-fired power plants that universal access to the country. With determination of greenhouse gas emission reduction effect, the south Korean government from the beginning on March 15, 2019, henan wind power projects in the whole South Korea coal-fired power plants in heavy oil. On the processing, and high acidity material, or remove color flavor, etc. In addition, according to south Korean oil management institute, biological heavy oil as raw materials for the generator is used, the new energy power generation project almost not exude the leading cause of haze & other; The murderer & throughout; Sulfuric acid compound, the discharge of greenhouse gases can also be reduced. Biological heavy oil largely depends on the by-products of biodiesel raw materials ( 27. 9%) By-products (or import palm oil and palm oil 51%) 。
