MODELLING AND SIMULATION OF PROCESS SYNTHESIS IN TERT-AMYL-METHYL-ETHER PRODUCTION VIA REACTIVE-DISTILLATION

摘要

The work presents a simulation study of a pilot scale catalytic distillation unit for tert-amyl-methyl-ether synthesis using HYSYS~(TM)simulation environment.A model having the parameters estimated from our own experimental data is used to describe the kinetics chemical reactions on the catalyst surface.The simulation model can be used as decision support in plant operation,the simulation times being small compared with the operation time scale.The reactive distillation column simulation was described using modules available in HYSYS? package.Three Hysys software modules were considered to simulate the column:a rebelled absorber(for the stripping zone),a refluxed absorber(for the rectifying zone)and a catalytic reactor(for the reaction zone).The validation of results was made comparing calculated and experimental values of iso-amylenes conversion and temperature profiles along a catalytic distillation unit.
