Modelling and control of an integrated high purity methanol distillation configuration

Process integration in distillation unit operations promises improved process efficiencies. However, to realize these benefits fit for purpose control structures are needed ensure stable and on-specification operations. In practice, this requires the development of regulatory advanced controls accounting nuances intricacies a given design application. This manuscript focuses on developing structure novel industrial mass-integrated twin-column configuration, where multi-component crude methanol feed is refined into AA grade (ultra-high purity) methanol, while meeting many technical economic requirements. To end, Digital Model (a dynamic model) column configuration was developed used carry out thorough analysis. Based understanding gained, layer introduced achieve An supervisory level Predictive Control (MPC) were then compared model both alternatives achieved (technical economic) It illustrated that well-designed could specific Further disturbance testing showed MPC marginal efficient than but has similar robustness.
