Abstract / Description:Alkylates are one of the probable replacements of MTBE as gasoline additives, which can be produced by dimerisation of isobutene (to isooctene) with subsequent hydrogenation. The characteristics of the dimerisation reaction make it a potential candidate for reactive distillation. In this work, process variants such as reactive distillation process, conventional reaction-separation network and distillation column with a side-reactor are compared by simulations. The influence of various design and operating parameters on the process performance of a hybrid reactive distillation column is studied. Results show that high selectivity towards diisobutene can be achieved along with adequate temperature control. Multiple steady states are also observed which introduce additional complexities in the determination of the optimal window for certain parameters. From our comparative study, it turns out that reactive distillation is the best process solution. It is capable of utilizing the existing refinery assets and also the feedstock for MTBE production by suitable revamping.
