WebDistillation is also an example of a multi-input multi-ouput (MIMO) process. Being an MIMO process, it cannot avoid the possibility of interactions between its variables. Distillation … WebReactive distillation (RD) is an important intensification technology that offers multiple advantages: 1. an improved chemical process (i.e. higher conversion and selectivity), 2. …
WebIn a reactive distillation column, both the chemical conversion and the distillative separation of the product mixture are carried out simultaneously. Through this integrative strategy, chemical equilibrium limitations can be overcome, higher selectivities can be achieved and heat of reaction can be directly used for distillation. Increased process efficiency and … WebThe purpose of this paper is to design and analyze the control structures of a consecutive reactive distillation process. On the basis of the optimal economic design, a systematic framework for the design of the decentralized control structure, controller parameter tuning, and setting profiles under uncertainty disturbances is proposed for benzene chloride …
WebReactive distillation (RD) with excess reactant is adopted in the study to improve reaction conversion and obtain high-purity products in the DEC synthesis. A base-case design, consisting of a RD column and a DEC purification column with its overhead unreacted ethanol stream recycled back to the RD column, is developed and optimized by ...
