＂Waste oil＂ turned into biodiesel and exported to EU.

An overview of journalist Zhang Xiaoyue

Using the waste oil which is sour, smelly, turbid and precipitated in the swill bucket, the biodiesel which is clear and transparent and will be exported to the EU is produced. On April 15th, the reporter saw a magical scene in Tangshan Jinlihai Biodiesel Co., Ltd. located in Luannan County.

Li Zhenjun, deputy general manager of Jinlihai Company, once hated cooking oil, the raw material for biodiesel production. swill-cooked dirty oilIf the reflux table is eaten by people, it will be harmful to health. "But we believe that there is no absolute garbage, only resources that are misplaced."

At the gate of the company, several tankers are transporting the purchased waste oil. So, how is waste oil converted into biodiesel? Li Zhenjun said that impurities should be removed by filtration, precipitation and centrifugation.

Subsequently, Li Zhenjun led the reporter to the reactor workshop, the most critical link of "turning waste into treasure". In a container just like a pot, methanol, sulfuric acid, etc. are added according to the ratio, and the glyceride in the gutter oil is decomposed into crude methyl ester.

Behind the reactor is a high distillation tower. In the tower, the crude methyl ester is further rectified. After the remaining plant asphalt is removed, methyl ester, which is often called biodiesel, remains.

The picture shows the distillation column, which is provided for enterprises.

The realization of the development and utilization of this series of waste oil stems from the power of science and technology. "The company has continuously carried out scientific research and invented 69 international and domestic patents in the field of biodiesel, and its technology in the field of comprehensive utilization of waste oils and fats is leading the world." Li Zhenjun said proudly.

After the production of biodiesel, the samples were sent to the real.Check the inside. The staff took samples from test tubes, tested the acid value, etc., and tested the composition of oil by gas chromatography.“This is new.What about energy? "Li Zhenjun told reporters.

He introduced that biodiesel takes plants and animal fats as raw materials. Compared with petrochemical diesel, it has the advantage of being friendly to the environment and forming a closed loop through the carbon sink of plants. Add 10% to 20% biodiesel to petrochemical diesel oil, and carry heavy trucks.The car added this blended oil,tailThe emission of PM 2.5-PM 10 pollution particles can be reduced by 48% to 86%. For every ton of biodiesel produced by the company, the emission reduction in the whole life cycle reaches 2.98 tons of carbon dioxide equivalent.

It is precisely because of its green, environmental protection and renewable characteristics that biodiesel meets the hard-core standards of European carbon emission assessment, so it is favored by European Union and other countries. Today, Jinlihai Company digests 200,000 tons of waste oil every year and produces 160,000 tons of biodiesel, about 80% of which are exported.

"In the past, EU countries also used rapeseed to produce biodiesel, but it is more cost-effective to use kitchen waste oil as raw material, and it reduces dependence on crops such as non-renewable mineral energy and food." Li Zhenjun said.

After that, he pointed to the Jingtang Port area in the southeast of the company, where there is a special export dock and storage tank for biodiesel, and it is also the only biodiesel bulk loading and unloading dock in the northern ports of China. "There are also European routes, which has accelerated the pace of our international capacity cooperation." Li Zhenjun said.

With the global consensus on climate change, and the proposal of "double carbon" goal in China in recent years, domestic diesel standards have been upgraded, and more and more petrochemical enterprises have mixed biodiesel with petrochemical diesel for automobiles and other uses to reduce pollution emissions.
