Book Description
As a result of fossil fuels-based energy production, reducing atmospheric carbon dioxide emissions has become an urgent issue. Especially, carbon capture and storage (CCS) technology, being one of the leading processes to reduce total carbon emissions, has become increasingly important. Hydrogen is an important energy carrier, and hydrogen-based technologies have increased in importance recently due to the worldwide focus on green processes. The Integrated Gasification Combined Cycle (IGCC) is a promising technology supplying clean energy at affordable prices. The IGCC process is currently being coupled with CCS technologies. However, using CCS technologies in power generation processes is a great challenge, necessitating the intensification of the coupled IGCC-CCS process. Process intensification (PI), leads to substantially smaller, cleaner, and more energy efficient processes, and is a prominent topic, receiving significant attention in recent years. As part of intensifying a process, integration of multiple operations (e.g., reaction and separation) in a single unit is often carried out, to improve the existing process efficiency, and to reduce energy consumption, and unwanted output/by-product generation. The objective of this work is to demonstrate the process intensification potential of a technology, containing one or more water gas shift (WGS) reactor components seamlessly integrated with other plant components. We investigate the applicability of various (alternative to the conventional process) novel and efficient reactor configurations that include self-standing adsorptive reactor (AR)/membrane reactor (MR), and the combination of a MR-LTSR-AR-adsorptive separator (AS)-membrane separation (MS) units (herein after referred to as the LTSR-MS/LTSR-AS/AS-LTSR-AS/MR-AS/AS-MR-AS/MR-AR systems). The proposed WGS reactor technologies have the potential to generate highly efficient and ultra-compact processes, by producing H2 for use in IGCC with simultaneous CO2 capture. Innovative designs of the proposed processes are determined based on the comprehensive modeling and design of the selected IGCC plant's section. Comprehensive, multi-scale, multi-phase, computational fluid dynamics (CFD) models are developed for reaction/separation processes. Developed models quantify the many complex physicochemical phenomena occurring within the process, thus providing the basis to better understand, and intensify the overall system. Model predictions are generated for a broad range of operating conditions and design parameters, thus enabling a comparative performance assessment of the proposed process versus a conventional process for the proposed IGCC application.

Book Description
The successful implementation of greener chemical processes relies not only on the development of more efficient catalysts for synthetic chemistry but also, and as importantly, on the development of reactor and separation technologies which can deliver enhanced processing performance in a safe, cost-effective and energy efficient manner. Process intensification has emerged as a promising field which can effectively tackle the challenges of significant process enhancement, whilst also offering the potential to diminish the environmental impact presented by the chemical industry. Following an introduction to process intensification and the principles of green chemistry, this book presents a number of intensified technologies which have been researched and developed, including case studies to illustrate their application to green chemical processes. Topics covered include: • Intensified reactor technologies: spinning disc reactors, microreactors, monolith reactors, oscillatory flow reactors, cavitational reactors • Combined reactor/separator systems: membrane reactors, reactive distillation, reactive extraction, reactive absorption • Membrane separations for green chemistry • Industry relevance of process intensification, including economics and environmental impact, opportunities for energy saving, and practical considerations for industrial implementation. Process Intensification for Green Chemistry is a valuable resource for practising engineers and chemists alike who are interested in applying intensified reactor and/or separator systems in a range of industries to achieve green chemistry principles.

Book Description
Abstract: A comprehensive process intensification analysis was performed for the integration of the Pd-based membrane reactor technology into IGCC power plants by designing effective process control strategies as well as identifying and optimally characterizing inherently safe operational conditions to achieve the most favorable economic outcomes. Experimental results indicated that Pd-based composite membranes supported on porous stainless steel tubes, fabricated with H2 permeance values as high as ~50 m3/[m2.h.atm0.5] at 450°C were capable of extra purity H2 production (≥99.99%). Two illustrative process control and performance monitoring cases namely, process regulation and servo mechanism, were considered and quite satisfactory process control was attained by maintaining CO conversion at levels higher than 95% so that the retentate stream could become suitable for high pressure CO2 sequestration. From a process safety standpoint, process parameters and operating conditions were identified and optimized to achieve the target performance level of 98% CO conversion and 95% H2 recovery and at the same time to prevent conditions which could potentially induce hazards and thus compromise process system safety. Furthermore, the average total product cost of a water-gas shift membrane reactor module including manufacturing costs and general expenses was carefully estimated by taking into account the full cost structure and found to be 1464 $/ft2. Moreover, a comprehensive economic assessment was performed for composite Pd/Alloy membrane reactor technology options integrated into IGCC power plants in the presence of market and regulatory uncertainty (possible regulatory action on CO2 emissions) as well as technology risks with the aid of Monte-Carlo simulation techniques. Within such a context, it was demonstrated that an IGCC plant with embedded Pd-based membrane reactors and a stream of revenues coming from electricity and H2 selling (IGCC co-production mode), represented an economically attractive and advantageous option when comparatively assessed against its main competitors namely, an IGCC plant with shift reactors and double stage Selexol units as well as the more traditional supercritical pulverized coal power plant option with an Econamine unit installed for CO2 capture purposes.

Book Description
This book investigates the development of sorption enhanced reaction processes (SERPs) with detailed modelling and simulation, design and operation of units. SERPs are processes intensified by combining adsorption and reaction, reaction and membranes or reaction/adsorption/membranes in a single unit in order to overcome thermodynamic limitations of conversion in reversible reactions. The focus here is on gas phase and liquid phase processes involving different technologies, including pressure swing adsorptive reactors, membrane reactors and simulated moving bed reactors. Emphasis is also given to presenting data and practical applications of SERP products.Sorption Enhanced Reaction Processes provides undergraduate and graduate students of chemistry and chemical engineering, researchers and industrial engineers with a clear path towards process development of SERP, whatever the area of application.
