METHOD FOR PRODUCTION OF COMMERCIAL-GRADE DIESEL FUEL OF HIGH-SULPHUR DIESEL OIL CUTS AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: oil and gas industry.;SUBSTANCE: invention refers to the method for production of commercial-grade diesel fuel of high-sulphur diesel oil cuts including division of the main flow of fuel fractions into three flows with subsequent treatment of each flow by the respective extractive agent and output from them of the received purified fraction to the neutralising unit outputting commercial-grade fuel; high-sulphur diesel oil cuts are used as fuel fractions; sulphuric acid is used as the extractive agent for purification of the first flow, extraction phase after the first flow purification is used for purification of the second flow, extraction phase after the second flow purification is used for purification of the third flow, at that extraction phase for the third flow is washed by process water. The invention refers also to the device for production of commercial-grade diesel fuel.;EFFECT: decreasing content of sulphur and nitrogen compounds and aromatic hydrocarbons.;3 cl, 1 dwg, 1 tbl, 1 ex
