METHOD OF PREPARATION OF HIGH-VISCOSITY AND PARAFFIN OILS FOR PIPE LINE TRANSPORTATION Russian patent published in 1997 - IPC

Abstract RU 2089778 C1

FIELD: pipe line transportation of oils. SUBSTANCE: method consists in reducing viscosity of oil. Liquid product of petroleum gas processing (mixture of light aromatic hydrocarbons, mainly benzene, toluene and xylenes) is introduced as hydrocarbon thinner in amount of 1 to 20 %-vol. during transportation of oil. Liquid products are obtained on zeolite- containing catalysts at 600-650 C, space velocity of raw material of 90 to 220h^-1 and atmospheric pressure. EFFECT: enhanced efficiency. 2 cl, 1 tbl
