January 3, provided by the Lanzhou Institute of Chemical Physics, Chinese Academy of patented technology to build an annual output of 2,500 tons of ethylene - vinyl acetate copolymer (EVA) and efficient diesel PPD production plant in Dongying, Shandong Branch of Petroleum Technology company once put to trial success and transferred to normal production. Products indicators meet the design requirements, add applications using a number of refinery diesel showed that the use of the depressant reduces cold filter plugging point 7 ℃ -14 ℃, and can be more reduced than the mainstream products on the market compared to the 2 ℃ -3 ℃, excellent performance.
EVA efficient diesel PPD project by the Chinese Academy of Sciences "Western Action Plan" to support the project, the core technology to obtain a Chinese invention patents, 500 tons of test products won the "National Key New Product" certificate. The first set of annual output of 2,500 tons of diesel depressant efficient device in 2004 in China PetroChina Lanzhou Petrochemical Company put into operation.
Run by Dongying Petroleum Technology Company is a petroleum technology development, production, sales and service in one enterprise, with an annual production of 2,500 tons efficient diesel PPD construction equipment by the company to obtain Dongying Economic and Information Technology Committee project and give financial support. After the project is put into production, annual output value of 60 million yuan, profits and taxes of up to 12 million yuan, providing 30 jobs for the community; while depressant to provide quality and efficient refinery products, used to enhance the quality and capacity of diesel.
EVA diesel PPD is a low molecular weight ethylene - vinyl acetate copolymer, is currently widely used in domestic and overseas markets for a class of diesel flow improvers. The depressant may improve the low temperature properties of diesel fuel, improve low temperature fluidity of diesel, increasing the yield of light diesel oil refineries and oil can also help solve the problem of substandard diesel fuel standards, saving reconcile with kerosene.
