New FCC process minimizes gasoline olefin, increases propylene

An FCC process called flexible dual-riser fluid catalytic cracking (FDFCC) can minimize gasoline olefins and increase propylene significantly. Using available FCC catalysts, the FDFCC unit produces a gasoline with 10-35 vol % olefins, while increasing propylene yield by about 6 wt % points vs. conve...

Description
Summary:An FCC process called flexible dual-riser fluid catalytic cracking (FDFCC) can minimize gasoline olefins and increase propylene significantly. Using available FCC catalysts, the FDFCC unit produces a gasoline with 10-35 vol % olefins, while increasing propylene yield by about 6 wt % points vs. conventional FCC units. These conclusions are based on demonstration trial runs of a 120,000tonne/year FDFCC unit, which was revamped from an existing residue fluid catalytic cracking unit. The FDFCC process, developed by Luoyang Petrochemical Engineering Corp., an affiliate of China Petroleum & Chemical Corp., is designed to minimize olefins in catalytically cracked gasoline, a dominant component of China's gasoline pool. The process was also designed to maximize propylene production in LPG when necessary.
