The synthesis of heat integrated multi-component distillation systems is complex due to its huge search space for structural combination and optimization computation. To provide a systematic approach and tools for the synthesis design of distillation systems, a new method for modeling heat integrated columns is presented, and the operating cost objective function is minimized by improved harmon...

In this work, we analyze the control properties of thermally coupled reactive distillation sequences and thermally coupled extractive distillation sequences in comparison with conventional reactive and extractive distillation configurations. All sequences have been designed using a multi objective genetic algorithm with restrictions. We study the theoretical control properties of those schemes ...

This paper applies Bayesian neural networks on the inference of diesel 85% ASTM distillation, and compares the results with traditional multi-layer perceptrons.

Topic distillation is the process of finding representative pages relevant to a given query. Well-known topic distillation approaches such as the HITS algorithm have shown to be useful in identifying high quality pages of the most popular topic within a query specific graph of hyperlinked documents. Many succeeding researchers focus on augmenting HITS with further content analysis to alleviate ...

Reactive distillation processes couple chemical reactions and physical separations into a single unit operation. The ethyl acetate production by esterification reaction is equilibrium limited and is suitable to be carried out in a distillation column. In the present work, a reactive distillation column for the production of ethyl acetate is simulated using Aspen Plus. The component compositions...

Reactive distillation is an excellent example of recent advances in process intensification. It combines reaction and separation operations in one piece of equipment. This paper studies the steady-state economic optimum design of a chemical process with a generic exothermic reversible reaction A+B↔C+D for two different process flowsheets: a conventional multi-unit reactor/separator/recycle stru...

The growing interest in intelligent services and privacy protection for mobile devices has given rise to the widespread application of federated learning Multi-access Edge Computing (MEC). Diverse user behaviors call personalized with heterogeneous Machine Learning (ML) models on different devices. Federated Multi-task (FMTL) is proposed train related but ML devices, whereas previous works suff...
