Study of Non-linear dynamics in Reactive Distillation for TAME synthesis using Equilibrium and Non-equilibrium models

摘要

The work emphasizes on non-linear dynamic effects in dynamic simulation with both Equilibrium (EQ) and non-equilibrium models. Both rigorous EQ and NEQ models result in high-index DAE systems. The variables responsible for the higher index in each case are identified and accordingly, model simplifications are made without compromising on essential dynamic terms. For certain conditions, dynamic simulation with EQ model leads to limit cycles. However, dynamic simulation with more realistic and rigorous NEQ model with identical operating conditions as the EQ model does not reveal any oscillatory behavior.
