Energy Optimization in Process Systems Book Review:

Despite the vast research on energy optimization and process integration, there has to date been no synthesis linking these together. This book fills the gap, presenting optimization and integration in energy and process engineering. The content is based on the current literature and includes novel approaches developed by the authors. Various thermal and chemical systems (heat and mass exchangers, thermal and water networks, energy converters, recovery units, solar collectors, and separators) are considered. Thermodynamics, kinetics and economics are used to formulate and solve problems with constraints on process rates, equipment size, environmental parameters, and costs. Comprehensive coverage of dynamic optimization of energy conversion systems and separation units is provided along with suitable computational algorithms for deterministic and stochastic optimization approaches based on: nonlinear programming, dynamic programming, variational calculus, Hamilton-Jacobi-Bellman theory, Pontryagin's maximum principles, and special methods of process integration. Integration of heat energy and process water within a total site is shown to be a significant factor reducing production costs, in particular costs of utilities for the chemical industry. This integration involves systematic design and optimization of heat exchangers and water networks (HEN and WN). After presenting basic, insight-based Pinch Technology, systematic, optimization-based sequential and simultaneous approaches to design HEN and WN are described. Special consideration is given to the HEN design problem targeting stage, in view of its importance at various levels of system design. Selected, advanced methods for HEN synthesis and retrofit are presented. For WN design a novel approach based on stochastic optimization is described that accounts for both grassroot and revamp design scenarios. Presents a unique synthesis of energy optimization and process integration that applies scientific information from thermodynamics, kinetics, and systems theory Discusses engineering applications including power generation, resource upgrading, radiation conversion and chemical transformation, in static and dynamic systems Clarifies how to identify thermal and chemical constraints and incorporate them into optimization models and solutions

23 European Symposium on Computer Aided Process Engineering Book Review:

Mathematical modelling and optimization of the natural gas based Distributed Energy Supply System (DESS), both at the building level and the overall energy supply network level was carried out for three types of micro-CHP – solid oxide fuel cells, Stirling engines, internal combustion engines – and for two operating strategies – cost-driven and primary energy-driven. The modelling framework has particularly allowed the quantification of the impact of micro-CHP on the total primary energy consumption at the whole network level. The result of a case study based on the UK reveals the range of the overall reduction in primary energy usage and central power plant capacity requirement and the range of the increase in natural gas supply to homes. The economic analysis shows that the coupling of different technologies, sizes of the CHP engine, and the operating strategies gives rise to a wide range of payback time.
