文摘

Simultaneous design encompassing flowsheet synthesis, optimization and plantwide control demonstrated for diisobutylene (DIB) manufacturing. Processes use tert-butyl alcohol (TBA) moderator, generated in-situ and recycled-to-extinction, for DIB yield enhancement. Two novel flowsheets, FS1 (brand new) and FS2, using a decanter for water recovery and recycle developed. FS1 and FS2 shown to achieve both high reactor conversion and DIB yield, unlike extant literature flowsheet, FS0. FS1 found to be superior to FS2 in terms of capital cost, energy efficiency and fresh water consumption. Demonstration of innovative control loops for yield and conversion regulation for “green” process operation.
