Reactive distillation design and control
WebMar 5, 2010 · Fig. 1 shows the process flowsheet of reactive distillation + pressure-swing distillation. We use ChemCad notation of numbering stages from the top, with stage 1 being the reflux drum. EC reactant with a flow rate of 25 kmol/h and a homogeneous catalyst (sodium methoxide, soluble in both EG and MeOH) are fed into a 45-stage reactive … WebThe fault detection of the chemical equipment operation process is an effective means to ensure safe production. In this study, an acoustic signal processing technique and a k-nearest neighbor (k-NN) classification algorithm were combined to identify the running states of the distillation columns. This method can accurately identify various fluid flow …

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, … WebReactive distillation is a breakthrough process innovation with numerous applicationsin the petroleum and chemical industries. In systems with the appropriate chemistryand vapor–liquid phase equilibrium, it combines the reaction and separation operations,which reduces energy and capital costs and environmental impact.
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 control is difficult due to high operational conditions [5] and therefore a control analysis in the design stage will be beneficial for the industry.
