the design and optimization of distillation column with heat and power integrated systems

The Design and Optimization of Distillation Column with Heat and Power Integrated Systems

Based on two integration steps, an optimization framework is proposed in this work for the synthesis and design of complex distillation sequence. The first step is to employ heat integration in sequence and reduce the heat consumption and total annual cost of the process. The second one is to increase the exergetic efficiency of sequence by generating power in implemented expanders in sequence....

Simultaneous Design of Heat Integrated and Thermally Coupled Distillation Systems

Abstract In this work we present a methodology for synthesizing sequences of columns that combine both, the heat integrated and the thermally coupled distillation columns. As a consequence it is possible to design systems capturing simultaneously the advantages of these two approaches. A superstructure based on separation tasks rather in actual columns is proposed. This approach is more flexibl...

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

Design of Integrated Real –time Optimization and Adaptive Model Predictive Control for Distillation Column

This paper presents two integration approaches of real-time optimization (RTO) and adaptive model predictive control (MPC) in the 2-layer and 3-layer structures and their applications to the distillation column. The 2-layer structure is constructed based on the conventional hierarchical control layer. In the 3-layer structure, the quadratic programming (QP) layer is inserted to compute the feas...
