Jumped chemical output of crude oil via one-step leaping over regular routes, an integrated molecular-level process modeling strategy and a many-objective optimization framework

Abstract

This study introduces a universality methodology to achieve the jumped chemical output of crude oil via one-step leaping over regular routes using the patented two-segment lift tube reactor. The integrated molecular-level modeling as well as many-objective optimization framework for crude oil direct hydrogenation coupled with a catalytic cracking reaction process using the two-segment lift tube reactor (CDHC) is also performed. Consequently, the CDHC process could solidly transform hydrotreated sulfur oil to chemicals with the sum of yields over 43 wt%. The non-renewable energy consumption of the optimized CDHC process decreased by 5.00%, the greenhouse gas emissions decreased by 4.09%, and the number of potential jobs available increased by 9.35%. This shows the leading technique, economics, livelihood, society, and environment character. The insights provided in this study may strongly promote the conceptual process design, engineering intensification together with many-objective optimization of oil direct hydrotreating coupled with catalytic cracking.
