Effect.of baffles on p.rformance of fluid cat.lyt.c cracking riser

作者： Milinkumar t. Shah Vishnu K. p.reek Geoffrey M. Evans Ranjeet.p. Ut.kar Dep.rt.ent.of Chemical Engineering Curtin University Western Australia Australia Dep.rt.ent.of Chemical Engineering University of Newcastle New South Wales Australia

Increasing demand of aut.mobile fuel and a need t. p.ocess heavier crude oil makes it.imp.rat.ve t. find imp.ovement. t. t.e design of exist.ng fluid cat.lyt.c cracking （FCC） unit.. Several modificat.ons t. t.e design of t.e riser sect.on of FCC unit. have been suggest.d in p.evious st.dies including： imp.oved feed nozzle designs, mult.p.e nozzle configurat.ons, int.rnal baffles, and novel t.o-st.ge-riser syst.ms. In t.is st.dy, we invest.gat. t.e effect. of baffles on t.e p.rformance of FCC risers using comp.t.t.onal fluid dynamics simulat.ons. In t.is st.dy, p.edict.ons from a basis model （wit.out.baffles） are comp.red wit. t.ose from four different.configurat.ons including：（i） 5-cm baffles at.5-m sp.cing, （ii） 7.5-cm baffles at.5- m sp.cing, （iii） 10-cm baffles wit. 5-m sp.cing, （iv） lO-cm baffles at.2.5-m sp.cing, and （v） lO-cm baffles at.1-m sp.cing. t.e baffles force t.e cat.lyst.away from wails t.ward t.e cent.r of t.e riser, enhancing t.e radial disp.rsion of t.e cat.lyst.and t.e heat.t.ansfer inside t.e riser. t.e use of longer baffles and smaller sp.cings furt.er increases t.e disp.rsion, yielding more homogeneous radial p.ofiles. t.e changes in t.e radial disp.rsion result.in variat.ons in t.e conversion, yields, and p.essure drop.. t.e baffles increase conversion of vacuum gas oil （VGO） and t.e yield of gasoline. However, t.e simulat.ons showed t.at.longer baffles and a larger number of baffles did not.always give a higher yield or higher conversion. Among t.e simulat.d configurat.ons, t.e 5-cm baffles at.5-m sp.cing gave t.e highest.conversion of VGO, whereas t.e 10-cm baffles at.1 -m sp.cing result.d in t.e highest.yield of t.e gasoline. t.us, rat.onal op.0}mizat.on of baffle configurat.ons is required t. achieve op.0}mal p.rformance.
