摘要

Clean fuel requirements for meeting Tier 2 Gasoline and ULSD specifications have increased the impactrnof process unit interactions. Together with added hydroprocessing capacity and capability, site-widernhydroprocessing strategies have required review to ensure that both clean fuels objectives can be metrneffectively.rnFCC feed hydrotreating has been typically operated for constant product sulfur, meeting previousrngasoline specifications or for hydroconversion of FCC catalyst poisons (nitrogen, polynuclear aromatics,rnconcarbon, etc.) providing increased FCC conversion. Prior to the requirement of 30 ppm sulfur gasoline,rnFCC feed hydrotreating optimization resulted in balancing these economics of cycle life versusrnconversion. The recent change in gasoline sulfur requirements has resulted in many refiners installingrngasoline post treat technology to meet this mandate. This has resulted in relaxing the previous FCC feedrnsulfur targets, requiring us to revisit how best to operate the FCC Pretreat/Cracker complex, whilernkeeping in mind the impact that these modes can now have on ULSD production. Being aware of therninteractions between the FCC Pretreat / Cracker complex and the ULSD units is key to a successfullyrnimplemented clean fuels strategy.rnIn addition to distillate unit revamps for ULSD production, Houston Refining, LP, a LyondellBasellrnCompany ("HRLP") has also recently added post-treat capability to meet Tier 2 gasoline requirements.rnAlong with these additional assets, significant increases in hydroprocessing performance have beenrnrecently achieved with Criterion Catalysts & Technologies ASCENT & CENTINEL GOLD family ofrncatalysts, requiring the refiner to review how best to utilize these new capabilities. Working together withrnCriterion Catalysts & Technologies, HRLP has reviewed a number of operational strategies and madernsome FCC feed hydrotreater technology improvements which should position HRLP well for meetingrnfuture refining challenges.rnThis paper outlines the gains obtained in pretreat performance via a combination of diagnostic operationalrnreview and catalyst product development and how current operational objectives are now being reviewedrnto maximize the overall facility performance. In finding these new capabilities, new operationalrnconstraints have been identified showing that operational excellence is found through a program ofrncontinuous improvement.
