In Order to Produce Low-Viscosity Deasphalted Hydrocarbon Feedstock and Asphalt Binders from Natural Bitumen

Guy B Marin

The peculiarities of the composition of natural hydrocarbon from Russia deposits bring about to more process and transportation issues thanks to necessity of construction of process units on the brink of their production areas. So as to unravel this drawback, a technique of pretreatment of natural hydrocarbon was planned; as a result, potential asphalt binders and low-viscosity deasphalted oil appropriate for transportation to refineries square measure created. Supported experimental information, the optimum conditions for the method was hand-picked. It had been suggested to hold out the primary stage of crude preparation, particularly thermo-mechanical dehydration of hydrocarbon, with Associate in nursing end-point for distillation of a 100°C and 50°C. This resolved the matter of stable waterhydrocarbon emulsions and more dewatering of hydrocarbon, and excluded the chance of destruction reactions leading to additional unstable organic compound compounds. At consequent stage, it had been planned to hold out the method of deasphalting of hydrocarbon with dissolvent at a solvent: crude quantitative relation of 3:1. Therefore, production of deasphalted oil, with consistency on the brink of that of natural oil, and asphalt, as a feedstock for the assembly of universal road hydrocarbon, meant for each summer and winter in operation conditions.
