membrane engineering in Process Intensification an overview
Journal of Membrane Science, 2011Co-Authors: Enrico Drioli, Andrzej Stankiewicz, Francesca MacedonioAbstract:Abstract One of the crucial challenges currently facing the world is “ to support sustainable industrial growth ”. A possible solution is offered by Process Intensification (PI), a design approach offering concrete benefits in manufacturing and Processing, substantially shrinking equipment size, boosting plant efficiency, saving energy, reducing capital costs, increasing safety, minimizing environmental impact and maximizing the raw materials exploitation. Membrane Processes address the goals of PI because they have the potential to replace conventional energy-intensive techniques, to accomplish the selective and efficient transport of specific components, and to improve the performance of reactive Processes. On a number of occasions, commercial conventional separation Processes in industry were converted to membrane separation Processes with significant reductions in cost, energy, and environmental impact. This paper discusses how membrane engineering contributes to realization of the principles of Process Intensification. An overview of current developments in the field of membrane operations and their place in the Intensification of chemical manufacturing and Processing is presented. Several cases of successfully commercialized technologies are discussed in detail. Finally, the opportunity to integrate conventional membrane units with innovative membrane systems or into existing industrial Processes is also emphasized.

application of generic principles of Process Intensification to solution crystallization enabled by a task based design approach
Chemical Engineering and Processing, 2010Co-Authors: Richard Lakerveld, Andrzej Stankiewicz, Herman J M Kramer, Johan GrievinkAbstract:The design of current industrial crystallizers is strongly focussed on optimization of known types of crystallization equipment. These crystallizers harbour various physical phenomena, which are strongly entangled. The application of generic principles of Process Intensification (PI) to crystallization Processes requires individual control over physical phenomena. A new design method is applied that exploits elementary Processing functions as building blocks for design instead of existing equipment, which enables the application of generic principles of PI. Innovations in the field of crystallization to manipulate shear forces, manipulate nucleation rates with external fields, and improve control over solvent removal with membranes are key technologies. A case study demonstrates the application of task-based design for solution crystallization. The results show how task-based design leads to high modularization of the Process representation and model architecture. In addition, task-based design enables the application of generic PI principles, which results in a large flexibility to manipulate final product quality. Future needs include generalization of task-based design for crystallization and development of novel technologies for single task manipulation.

structure energy synergy time the fundamentals of Process Intensification
Industrial & Engineering Chemistry Research, 2009Co-Authors: Tom Van Gerven, Andrzej StankiewiczAbstract:Process Intensification (PI) is commonly seen as one of the most promising development paths for the chemical Process industry and one of the most important progress areas for modern chemical engineering. Often illustrated with spectacular examples, Process Intensification struggles, however, with its definition and interpretation. Instead of narrowing the scientific discussion down to finding a commonly accepted definition of PI, it is more important to determine its position within chemical engineering and to identify its fundamentals. Accordingly, the paper presents a fundamental vision on Process Intensification. The vision encompasses four approaches in spatial, thermodynamic, functional, and temporal domains, which are used to realize four generic principles of PI. The approaches refer to all scales existing in chemical Processes, from molecular to meso- and macroscale, and are illustrated with relevant examples with special attention given to the molecular scale.

Process Intensification and Process systems engineering a friendly symbiosis
Computers & Chemical Engineering, 2008Co-Authors: J A Moulijn, Andrzej Stankiewicz, Johan Grievink, Andrzej GorakAbstract:An attempt is presented to define Process Intensification in relation to the other chemical engineering disciplines, in particular to Process systems engineering. It is shown that Process Intensification is fully in development and, as a consequence, the essential characteristics are subject to debate. The innovative character of Process Intensification is in nice harmony with the objectives of Process systems engineering: a symbiosis between them has high potential.

Process Intensification of high gravity reactor for enviromental engineering from fundamental to industrialization
Scientia Sinica Chimica, 2014Co-Authors: Haikui Zou, Hong Zhao, Guangwen Chu, Yang Xiang, Jianfeng ChenAbstract:Sour gaseous pollutants released from the industrial tail or flue gas are the key source leading to serious environmental pollution. To meet the newly national regulation of the ultra-low emission limitation control of those sour gaseous pollutants in China, a new Process Intensification technology based on the high-gravity reactor (HGR) was proposed. The Intensification principles and routes of the high-gravity reactor for sour gas separation by reactive absorption were elucidated and verified from lab scale to fully industrial scale. The higher selectivity of removal of SO2, H2 S and CO2 from acidic gas mixtures could be realized by high-gravity technology using its advantages of intensifying mass transfer by orders of magnitude as well as the ultra-short residence time. Thus the ultra-low emission of sulfide was guaranteed by using HGR technology. A three-in-one scale-up method, i.e. "scientific experiments+mechanism model at microscale+CFD simulation at macroscale" of HGR was proposed and verified by industrialization practice. The largest scale high-gravity reactor (rotor diameter 3.5 m, casing diameter 5 m, capacity for gas flowrate 20×104 Nm3/h) in the world was developed and successfully implemented in the industrialization application of desulfurization. This breakthrough technology of Process Intensification has been now widely accepted and applied in industries for removing SO2 from tail gas and H2 S from petroleum or natural gases, as well as CO2 capture from flue gas of power plants, etc. The case studies of them were reviewed in this work.

high gravity Process Intensification technology and application
Chemical Engineering Journal, 2010Co-Authors: Hong Zhao, Lei Shao, Jianfeng ChenAbstract:Abstract Process Intensification has long been known to be a vital concept and is considered to be one of the fundamental pillars of the chemical engineering domain. This paper reviews the advances on the high-gravity (Higee) technology, including the theoretical studies on liquid flow, gas–liquid mass transfer, residence time distribution and micromixing, and the applications of Higee technology in absorption, stripping, nanoparticles preparation and other fields such as sulfonation, polymerization, synthesis of diphenyl-methane-diisocyanate and emulsification. The application of Higee in industry shows good adaptabilities of this technology and brings considerable profits.

Process Intensification for post combustion co2 capture with chemical absorption a critical review
Applied Energy, 2015Co-Authors: Meihong Wang, C Ramshaw, Atuman Samaila Joel, Dag Eimer, Nuhu Mamman MusaAbstract:The concentration of CO2 in the atmosphere is increasing rapidly. CO2 emissions may have an impact on global climate change. Effective CO2 emission abatement strategies such as carbon capture and storage (CCS) are required to combat this trend. Compared with pre-combustion carbon capture and oxy-fuel carbon capture approaches, post-combustion CO2 capture (PCC) using solvent Process is one of the most mature carbon capture technologies. There are two main barriers for the PCC Process using solvent to be commercially deployed: (a) high capital cost; (b) high thermal efficiency penalty due to solvent regeneration. Applying Process Intensification (PI) technology into PCC with solvent Process has the potential to significantly reduce capital costs compared with conventional technology using packed columns. This paper intends to evaluate different PI technologies for their suitability in PCC Process. The study shows that rotating packed bed (RPB) absorber/stripper has attracted much interest due to its high mass transfer capability. Currently experimental studies on CO2 capture using RPB are based on standalone absorber or stripper. Therefore a schematic Process flow diagram of intensified PCC Process is proposed so as to motivate other researches for possible optimal design, operation and control. To intensify heat transfer in reboiler, spinning disc technology is recommended. To replace cross heat exchanger in conventional PCC (with packed column) Process, printed circuit heat exchanger will be preferred. Solvent selection for conventional PCC Process has been studied extensively. However, it needs more studies for solvent selection in intensified PCC Process. The authors also predicted research challenges in intensified PCC Process and potential new breakthrough from different aspects.

reactive distillation stepping up to the next level of Process Intensification
Industrial & Engineering Chemistry Research, 2019Co-Authors: Anton A Kiss, Megan Jobson, Xin GaoAbstract:Reactive distillation (RD) is an efficient Process Intensification technique that integrates chemical reaction and distillation in a single apparatus. The Process is also known as catalytic distillation when a solid catalyst is used. RD technology has many key advantages such as reduced capital investment and significant energy savings, as it can surpass equilibrium limitations, simplify complex Processes, increase product selectivity, and improve separation efficiency. However, RD is also constrained by thermodynamic requirements (related to volatility differences and heat of reaction), the need to align the reaction and distillation operating conditions, and the availability of catalysts that are active, selective, and with sufficient longevity. This paper is the first to provide an overview and insights into novel integrated reactive distillation technologies that combine RD principles with other intensified distillation technologies—e.g., dividing-wall column (DWC), cyclic distillation, HiGee distilla...

Process Intensification of Multipressure Reactive Distillation Networks Using Infinite Dimensional State-Space (IDEAS)
2019Co-Authors: Flavio Eduardo Da Cruz, Vasilios I ManousiouthakisAbstract:The Infinite Dimensional State-Space (IDEAS) conceptual framework is put forward as an Intensification tool for the synthesis of globally optimal, multipressure, reactive, azeotropic, distillation networks. To this end, a unit operation model is proposed for reactive vapor–liquid equilibrium flash separators employed as network building blocks, and the concepts of reactive holdup and capacity are introduced as network performance metrics. The method is demonstrated on a case study involving MTBE production using multipressure reactive distillation of methanol/isobutene/MTBE azeotropic mixtures. The globally optimal solutions for the minimum total reactive holdup, minimum total flow, and minimum capacity problems are obtained for a dual-pressure reactive distillation Process operating simultaneously at 1.0 and 5.0 atm. For the problem of minimum capacity, the global optimum is found to have both reaction and pressure swing features, indicating those are complementary rather than competing technologies for Process Intensification purposes

Process Intensification of reactive separator networks through the ideas conceptual framework
Computers & Chemical Engineering, 2017Co-Authors: Flavio Eduardo Da Cruz, Vasilios I ManousiouthakisAbstract:Abstract A method to rigorously identify the performance limits of a reactive separator network is presented in this paper. The quantification of the enhancement potential for a given technology can greatly benefit Process Intensification studies in the pursuit of radical improvements. The Infinite DimEnsionAl State-Space (IDEAS) conceptual framework is first reviewed and then shown to be capable of assessing the potential for Process Intensification of reactive separation Processes. The IDEAS framework is employed to formulate an infinite linear program (ILP) that can synthesize optimal reactive separation networks, and establish rigorous tradeoffs between total network reactive holdup, and total network capacity. The proposed reactive separation Process Intensification method is demonstrated on a case study involving the metathesis of 2-pentene through reactive distillation. Significant Intensification over prior designs is demonstrated.
