Dynamic Evidence of Multiplicity in a Reactive Distillation Column for Ultra-Low Sulfur Diesel Production Dynamic Evidence of Multiplicity in a Reactive Distillation Column for Ultra-Low Sulfur Diesel Production

The objective of the work is to analyze and predict the multiple steady states through dynamic analysis when the reactive distillation column is subject to different input disturbances. The dynamic simulations are carried out to analyze the open loop dynamic responses of the system using step changes in the manipulated variable (reflux ratio, holdup, hydrocarbon mixture feed stage, hydrocarbon mixture feed flowrate, reboiler duty) and recording the dynamic behaviour of the product conversions (dibenzothiophene and 4,6-dimethyldibenthiophene, called controlled variables). The magnitude of the change in the manipulated variables should be reduced to around 0.5% or less than its nominal value.
