In the last decade, maximizing refinery production of polymer-grade propylene (PGP) has gained importance due to high demand from the petrochemical industry. Recently, highly flexible fluid catalytic cracking units (FCCUs)—capable of processing a wide range of feeds, from atmospheric residue to light naphtha, at various process conditions—have become key candidates in bridging the gap between the supply and demand of propylene. This process secures the integration of refinery-petrochemical operations. Due to the cryogenic nature of the olefins producing, gas processing units downstream of the FCC, pipelines are prone to hydrates, even at low-moisture content. The formation and plugging of h
