Book Description

In this thesis, we study the modeling and simulation of a reactive distillation column for the production of ethyl acetate from acetic acid and ethyl alcohol using ASPENPLUS. Starting from a conventional configuration, which involves feeding in a single tray, different configuration is proposed and various specifications are studied for the attainment of higher conversion and purity at the steady state. In ASPEN DYNAMICS an analysis of the column dynamics is then performed. Cascade control structure is studied for the base design.

Book Description

Reactive distillation (RD), the combination of chemical reaction and distillation in a single unit operation, has proven to be advantageous over conventional process systems consisting of separate reactor and distillation units. But the dynamic behavior of process is difficult to study. In this thesis, a reactive distillation column for ethyl acetate production has been created in ASPEN user interface. Steady state simulations are done in ASPEN user interface and the effect of reflux ratio on the composition of ethyl acetate in the distillate is studied. In ASPEN DYNAMICS the composition control studies for ethyl acetate purity has been studied both in the distillate and in the bottoms.

Book Description

The purpose of this book is to offer readers important topics on the modeling, simulation, and optimization of distillation processes. The book is divided into four main sections: the first section is introduction to the topic, the second presents work related to distillation process modeling, the third deals with the modeling of phase equilibrium, one of the most important steps of distillation process modeling, and the the fourth looks at the reactive distillation process, a process that has been applied successfully to a number of applications and has been revealed as a promising strategy for a number of recent challenges.

Book Description

Ethyl acetate (EtAc) is mainly used as solvent in paints, adhesives and coatings, eliminating the use of aromatic compounds. Reactive distillation is a type of process intensification in which the separation and reaction is combined in one vessel. In this work, reactive distillation (RD) process for EtAc was implemented using process simulator Aspen HYSYS by applying the data obtained from the bibliography. A sensitive analysis was performed to determine the effects of key design and operating variables on column performance and, subsequently, an optimal column configuration was obtained.

Book Description

Reactive distillation is a multi-functional unit operation combining chemical reactor and distillation column in a single unit. Fatty acid esterification is increasingly realized as a reactive distillation (RD) process because of its formation being affected by the chemical equilibrium. In this work, a detailed mathematical dynamic rate-based model of reactive batch distillation column is formulated for ethyl acetate synthesis and presented as a system of differential and algebraic equations (DAEs). The developed model is then solved to obtain the detailed column dynamics. The simulation results provide the dynamics of reboiler and distillate compositions, ethyl acetate purity in the accumulated distillate and conversion of the reactants. These simulation results are compared with experimental data, and it indicates a very good agreement. The developed model is then applied to formulate dynamic optimization problem in order to derive the optimum operating policy, reflux profile.

Book Description

A timely treatment of distillationcombining steady-state designand dynamic controllability As the world continues to seek new sources of energy, the distillation process remains one of the most important separation methods in the chemical, petroleum, and energy industries. And as new renewable sources of energy and chemical feedstocks become more universally utilized, the issues of distillation design and control will remain vital to a future sustainable lifestyle. Distillation Design and Control Using Aspen Simulation introduces the current status and future implications of this vital technology from the dual perspectives of steady-state design and dynamics. Where traditional design texts have focused mainly on the steady-state economic aspects of distillation design, William Luyben also addresses such issues as dynamic performance in the face of disturbances. Utilizing the commercial simulators Aspen Plus and Aspen Dynamics, the text guides future and practicing chemical engineers first in the development of optimal steady-state designs of distillation systems, and then in the development of effective control structures. Unique features of the text include: * In-depth coverage of the dynamics of column design to help develop effective control structures for distillation columns * Development of rigorous simulations of single distillation columns and sequences of columns * Coverage of design and control of petroleum fractionators Encompassing nearly four decades of research and practical developments in this dynamic field, the text represents an important reference for both students and experienced engineers faced with distillation problems.

Book Description

Chemical process industries deal with production which further utilizes reaction followed by separation of the reaction mixtures. Reactive distillation is a new technique of combination of both reaction and separation in a single unit beneficial for equilibrium-limited reactions and also cost-effective. This makes it a highly complex process because many parameters involved in both reaction and separation are interactive in nature. In this chapter, modeling, simulation, and optimization of reactive distillation are presented. Methyl acetate production via reactive distillation is chosen as a case study. The results are compared for both experimental and simulation studies. The synthesis of methyl acetate was carried out in a packed RDC by catalytic esterification using acetic acid and methanol as reactants in a pilot-scale experimental setup. A strong acidic ion exchange catalyst, Amberlyst-15, was used to enhance the rate of heterogeneous esterification reaction. The result obtained was observed with change in various variables including the reflux ratio (RR), distillate-to-feed (D/F) ratio, and bottom-to-feed (B/F) ratio with respect to product composition. The optimization and sensitivity analysis was carried out using Aspen Plus process simulation software.

Book Description

After an overview of the fundamentals, limitations, and scope of reactive distillation, this book uses rigorous models for steady-state design and dynamic analysis of different types of reactive distillation columns and quantitatively compares the economics of reactive distillation columns with conventional multi-unit processes. It goes beyond traditional steady-state design that primarily considers the capital investment and energy costs when analyzing the control structure and the dynamic robustness of disturbances, and discusses how to maximize the economic and environmental benefits of reactive distillation technology.
