The possibility of obtaining promising road bitumenes of PG grades under the conditions of the project for the installation of AVT-6 PJSC Bashneft-Ufaneftekhim

Abstract

The article investigates possible options for processing heavy oils entering refineries separately or when they are processed together with the oils of West Siberian deposits according to the bitumen profile. It is shown that the production of demanded unmodified grades of road bitumen PG 64-28 and PG 58-34 according to GOST R 58400.1 in the conditions of weighting of crude oil during the implementation of the ELOU-AVT-6 installation project at Bashneft-Ufaneftekhim, it is possible if measures are taken to compensate for the deficit in paraffin-naphthenic and aromatic compounds. For the production of these PG grades, an increased introduction of the TVG of this installation is required (from 25 to 40 %), however, it will not require the use of the TVG from AVT, which are in demand for oil production, processing mainly oil from West Siberian fields, or plasticizing components from the oil production complex (selective purification extracts).
