Paraffin-containing systems, such as waxy crudes, leave extensive wax deposits on pipeline walls and greatly adds to pipeline costs. It is proposed that solid hydrocarbons be extracted from raw crudes by adduct formation with urea. The petroleum would be separated into basic groups of hydrocarbons: normal-structure paraffins, and cyclic paraffins. Mangyshlak, Dolina, and Romashinko crude were treated. It is shown that by changing the rheological properties of crude oil by extracting the normal-structure hydrocarbons, it becomes possible to transport high-wax and medium-wax crude through pipelines with several advantages as specified.
