Insights on the dynamic behavior of thermally coupled distillation columns implemented on processes with recycles

Controllability Analysis of Distillation Sequences for the Separation of Bio‐Jet Fuel and Green Diesel Fractions

“…Recently, advanced control strategies for the control of thermally coupled systems have been proposed, such as model predictive control 16–18 and fuzzy control 19, among others. Also recently, Ramírez‐Corona et al 20 presented a control analysis of thermally coupled distillation columns, considering not only the isolated equipment but the interactions with whole processes.…”

Design and Control of Different Pressure Thermally Coupled Reactive Distillation for Methyl Acetate Hydrolysis

“…Reactive distillation integrates the reaction and separation into a single column, and it offers several potential benefits, such as improving reaction conversion, increasing product selectivity, and reducing energy requirements . On the other hand, thermally coupled distillation technologies have received great attention, which can achieve both energy and capital cost savings through eliminating the condensers/reboilers of the classical distillation columns. − A heat integrated distillation column (HIDiC) is proposed as a promising separation technology; it consists of a rectifying column and a stripping column. A lot of internal heat exchangers are used to transfer heat between the overhead vapor of the rectifier and the bottom liquid of the stripper, through which reboiler duty can be reduced significantly .…”
