Abstract: In this paper, processing routes for a new refinery with ten million tons capacity were studied, and the impacts of different processing routes on unit configuration, product structure, investment and economic benefits were discussed. The results showed that it is feasible for a ten million tons refinery to produce chemical products and aromatics. When the scale of ethylene and PX is constant, the slurry bed residue hydrocracking + fixed bed residue hydrotreating + catalytic cracking route has the highest yield of oils (including gasoline, kerosene and diesel), while the slurry bed hydrocracking + deep catalytic cracking route has the highest yield of gasoline, and the slurry bed hydrocracking + VGO hydrocracking route has the highest yield of kerosene and diesel. From the aspect of chemical product, combined technology of residue hydrocracking, residue hydrotreating and deep catalytic cracking can increase the yield of ethylene and propylene about 4%-5%, 5%-6%, respectively. The slurry bed hydrocracking + VGO hydrocracking route has the lowest investment and the highest benefit rate and is a better and shorter processing route to realize transformation of refineries than other routes.
