Introduction:
TheMcDermottethyleneconversiontechnologyhasrevolutionizedthepetrochemicalindustryandhassignificantlyimpactedtheproductionofethylene,akeybuildingblockforvariouschemicalsandpolymers.Oneoftheapplicationsofthistechnologyisinthepropanedehydrogenationplants,whichareknownfortheirefficientandsafeconversionofpropanetopropylene.Inthispaper,wewilldiscusstheapplicationofMcDermottethyleneconversiontechnologyinaTexas-basedalkylatingunit.
OverviewofMcDermottEthyleneConversionTechnology:
TheMcDermottethyleneconversiontechnologyisbasedontheuseofproprietarycatalystsandnovelreactordesigns,whichallowforefficientethyleneconversion.Thetechnologyinvolvestheuseofafluidizedbedreactor,whichisfedwithamixtureofethyleneandadilutinggassuchasnitrogen.Thecatalystsusedinthereactoraredesignedtopromotetheconversionofethylenetohigherolefins,primarilypropylene,butene,andpentene.Thereactiontakesplaceathightemperaturesandunderelevatedpressures,typicallyintherangeof1-3MPa.Thereactordesignissuchthatthecatalystsremaininthebedanddonotexitthereactorwiththeproductstream.
ApplicationinAlkylatingUnits:
