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.
利用焦油加工的汽油馏分作为热解原料的效率
有机合成领域(塑料、合成洗涤剂、橡胶等)是以烯烃和二烯烃的热解产物加工为基础的。随着世界范围内对基础石化产品需求的增加,对热解原料本身的需求也在增加,而热解厂目前面临的问题之一是向其提供原料。目前,Sumgayit石化总厂EP-300裂解装置的原料供供量低于装置需要的数倍,原料装载不完全影响了该工艺主要产品乙烯和丙烯的成本,最终影响了整个工业的性能。因此,研究了利用重油渣油加工过程中劣质汽油馏分(包括焦油焦化和加氢裂化所得汽油)作为热解原料的可能性,以及工艺强化对生产效率的影响。
