“…In general terms, intensification implies the reduction of inventory through smaller equipment, improvement of the reaction zone, and minimization of energy and raw material consumption , leading to cleaner and more energy-efficient designs compared to a conventional case study . Based on these definitions, different approaches have been presented. − One of the formal methodologies was developed based on phenomena building blocks (PBBs) which generate intensified alternatives that can be economically optimized . Subsequently, life cycle assessment (LCA) was included in the methodology described above as part of a criterion for evaluating the intensified alternatives …”

In this work, process intensification and heat integration are applied to improve a palm oil biofuel production process using modularity analysis and evaluated through techno-economic analysis and life cycle assessment (LCA). The modularity analysis integrated with the safety indicator guided the scoping of intensification options and the application of the LCA at the level of process modules that facilitate the treatment of recycles. Two alternatives are presented: the first is the intensified one only and the second is the addition of heat integration. In both cases, there was an improvement in economic terms by decreasing utility costs by 2 and 70%, respectively. In environmental terms, the global warming potential obtained is 12.8 kg CO2 eq./GJ for the intensified design and 12.2 kg CO2 eq./GJ for the intensified and integrated design, which is a considerable improvement over other studies that have been carried out. In addition, process safety was improved as the fire and explosion damage rate decreased by 15% in the separation section. In conclusion, this work demonstrated a novel application of modularity to scope intensification opportunities, implement LCA models at the modular level, and identify hot spots.

Membrane Fouling Phenomena in Microfluidic Systems: From Technical Challenges to Scientific Opportunities

2021

View full text Add to dashboard Cite

The almost ubiquitous, though undesired, deposition and accumulation of suspended/dissolved matter on solid surfaces, known as fouling, represents a crucial issue strongly affecting the efficiency and sustainability of micro-scale reactors. Fouling becomes even more detrimental for all the applications that require the use of membrane separation units. As a matter of fact, membrane technology is a key route towards process intensification, having the potential to replace conventional separation procedures, with significant energy savings and reduced environmental impact, in a broad range of applications, from water purification to food and pharmaceutical industries. Despite all the research efforts so far, fouling still represents an unsolved problem. The complex interplay of physical and chemical mechanisms governing its evolution is indeed yet to be fully unraveled and the role played by foulants’ properties or operating conditions is an area of active research where microfluidics can play a fundamental role. The aim of this review is to explore fouling through microfluidic systems, assessing the fundamental interactions involved and how microfluidics enables the comprehension of the mechanisms characterizing the process. The main mathematical models describing the fouling stages will also be reviewed and their limitations discussed. Finally, the principal dynamic investigation techniques in which microfluidics represents a key tool will be discussed, analyzing their employment to study fouling.
