The emerging FCC-based technologies are applied in an attempt to shift to the production of designated light olefins (including mainly ethylene and propylene) as well as light aromatics (including benzene, toluene, and xylene) developed by the Research Institute of Petroleum Processing (RIPP), SINOPEC. The RIPP’s proprietary technologies covering the Deep Catalytic Cracking (DCC), the Enhanced Deep Catalytic Cracking (DCC-PLUS), and the Maximizing Catalytic Propylene (MCP) have been playing decisive roles in the processing of crude aimed at closer integration of petroleum refining and petrochemical production both inside and outside of China since 1990. Three cases of commercial applications in five refineries, including Case I — the closer integration between the steam cracker and the DCC/DCC-PLUS unit, Case II — the petrochemical refinery provided with a DCC-PLUS unit, and Case III — the integrated petrochemical/fuels refinery provided with a MCP unit, have highlighted their far-reaching effects on global petrochemicals production.
