Efficiency of using gasoline fractions of tar processing as a raw material for pyrolysis

Abstract

The field of organic synthesis (plastics, synthetic detergents, rubbers, etc.) is based on the processing of olefins and diolefins - pyrolysis products. As demand for basic petrochemical products increases worldwide, so does the need for pyrolysis feedstock itself, and today one of the problems of pyrolysis plants is to provide them with feedstock. Currently, the amount of raw materials supplied to the pyrolysis unit EP-300 of the Sumgayit petrochemical complex is several times lower than the needs of the plant, and incomplete loading of the plant with raw materials negatively affects the cost of the main products of the process: ethylene and propylene, and ultimately on the performance of the entire industry. Therefore, the possibility of using low-quality gasoline fractions of the processing of heavy oil residues, including gasolines from coking and hydrocracking of tar, as a raw material for pyrolysis, as well as the effect of process intensification on production efficiency were studied.
