The crude oil refining processing sequence is based on the separation of distillate products from heavier ones and concentrating the heavy molecules of the barrel for processing at the end of the refining run. Processes developed to convert the concentrated bottom of the barrel into valuable distillates include hydrocracking or coking (hydrogenation or carbon rejection methods). In essence, the processes to convert the long-chain hydrocarbons—which are heavily concentrated in the bottom of the barrel—are complex, costly and limited to larger-sized units (e.g., 30,000-bpd minimum crude throughput). Reverse refining This article will detail several benefits of first converting the heavy mole
