Understanding Batch Chemical Processes

Modelling and Case Studies

By: Thokozani Majozi,Esmael R. Seid,Jui-Yuan Lee

Batch chemical processes, so often employed in the pharmaceutical and agrochemical fields, differ significantly from standard continuous operations in the emphasis upon time as a critical factor in their synthesis and design. With this inclusive guide to batch chemical processes, the author introduces the reader to key aspects in mathematical modeling of batch processes and presents techniques to overcome the computational complexity in order to yield models that are solvable in near real-time. This book demonstrates how batch processes can be analyzed, synthesized, and designed optimally using proven mathematical formulations. The text effectively demonstrates how water and energy aspects can be incorporated within the scheduling framework that seeks to capture the essence of time. It presents real-life case studies where mathematical modeling of batch plants has been successfully applied.

Batch Chemical Process Integration

Analysis, Synthesis and Optimization

By: Thokozani Majozi

“Batch Chemical Process Integration: Analysis, Synthesis and Optimization” is an excellent source of information on state-of-the-art mathematical and graphical techniques for analysis, synthesis and optimization of batch chemical plants. It covers recent techniques in batch process integration with a particular focus on the capabilities of the mathematical techniques. There is a section on graphical techniques as well as performance comparison between graphical and mathematical techniques. Prior to delving into the intricacies of wastewater minimisation and heat integration in batch processes, the book introduces the reader to the basics of scheduling which is aimed at capturing the essence of time. A chapter on the synthesis of batch plants to highlight the importance of time in design of batch plants is also presented through a real-life case study. The book is targeted at undergraduates and postgraduate students, researchers in batch process integration, practising engineers and technical managers.

23 European Symposium on Computer Aided Process Engineering

An Integrated Platform for Optimization of Heat and Water Use in Multipurpose Batch Plants

By: Esmael R. Seid,Thokozani Majozi

Energy optimization and the optimization of water use have mainly been treated as separate problems in literature. The batch production schedules resulting from each of these formulations do not guarantee that the plant is operated optimally. Presented in this contribution is a formulation that addresses the optimization of both water and energy, while simultaneously optimizing the batch process schedule. The scheduling framework used in this study is based on the formulation by . This formulation has been shown to result in a significant reduction of computational time, an improvement of the objective function and leads to fewer time points. The objective is to improve the profitability of the plant by minimizing wastewater generation and utility usage. From a case study it was found that through only applying water integration the cost is reduced by 11.6%, by applying only energy integration the cost is reduced by 29.1% and by applying both energy and water integration the cost is reduced by 34.6%. This indicates that optimising water and energy integration in the same scheduling framework can reduce the operating cost and environmental impact significantly.

23 European Symposium on Computer Aided Process Engineering

Overall Optimization of a Comprehensive Utility System

By: Mkhokheli Ndlovu,Thokozani Majozi

This contribution follows the earlier work by on the optimization of a comprehensive power plant utility system, a system consisting of a boiler and a cooling tower. Unlike previous research on the power plant utility system which had focused on the boiler and cooling water systems in a discrete manner, the authors presented a holistic method of analysis and treatment of the combined utility system. In this work further details of the nonlinear comprehensive system model are presented and the objective is maximizing the net revenue from operating the utility system, which is the difference between the total operating costs and the proceeds from the sale of electricity. The work has shown that up to 8 % increase in revenue is achieved when the process is optimized as a single utility system.
