Study of Impact of Selective Raw Cleaning on Extracts Properties

Abstract

The article is focused on the study of the impact of the intensity of oil vacuum draws and deasphaltizates cleaning of Kazakhstan blended crudes on physicochemical properties of extracts and on the types and quantity of components, extracted from raw to determine feasibility of their extraction from fine cleaning extracts.
