Vivek Ranade is a Professor of Chemical Engineering at the School of Chemistry and Chemical Engineering of Queen’s University Belfast. His research focus is on sustainable energy, water and fine & specialty chemicals. Earlier led chemical engineering at CSIR - National Chemical Laboratory. Contributed significantly to chemical engineering science and practice. Developed performance enhancement solutions, software products and fluidic devices for variety of applications which are commercialized. Developed new insights and methodologies for process intensification. Conceived and led a large program on development of MAGIC (modular, agile, intensified & continuous) processes & plants. Worked also at ETH Zurich, Switzerland (1988-90); TU Delft (1993-94) and University of Twente (1997-98), The Netherlands. Published more than 150 papers and 6 books (h index=42: from Google Scholar). Co-inventor of more than 20 patents. Co-founded two technology companies: Tridiagonal Solutions and VIVIRA Process Technologies.
The manufacturing processes of chemicals and materials are underpinned by complex mass, momentum and energy interactions. Our research is focused on developing fundamental understanding of these interactions and using it to conceive better (safer, cleaner, smaller and cheaper) transformation processes. We are addressing scientific questions in following areas with emphasis on developing competencies for resolving real life challenges:
Phase change processes such as boiling, cavitation, crystallization and precipitation play crucial role in many transformation processes. Significant enhancements in productivity and new applications/ products can be realized if these processes are adequately understood. We are carrying out experimental and computational investigations so as to develop mastery on flows with phase change. Aim is to develop a multi-scale modelling framework to tie together models addressing different scales and realize a ‘virtual process engineering’ toolkit for designing processes with phase changes.

Intensification is intrinsic to better chemical and process engineering and has always been used in practice. There is a great scope for intensifying multiphase reactions and reactors for realizing productivity enhancements, which are crucial for sustainable manufacturing. These enhancements can be in terms of increased throughput; better yield, conversion, and selectivity; smaller environmental footprint; and intrinsically safer operations. We develop different strategies for intensifying multiphase reactions and reactors. Aim is to pave the way towards realizing next generation productivity for chemical and allied industries.

This research is expected to generate new knowledge on multiphase systems, phase changes, chemical and physical interactions and multi-scale physicochemical models of commercially relevant systems. This new knowledge is expected to expand, enrich and strengthen the chemical engineering domain and impact on society. New knowledge and insights gained through these will be applied to realize significant impact in the following areas:
The focus is on developing and using process intensification strategies to realize modular, compact and continuous processes for fine and specialty chemicals. Significant improvements in (1) consumption of raw materials and utilities (2) product quality and (3) safety will be realized. The ideas and methodology will also lead to reduction in spatial as well as environmental foot print of these manufacturing facilities.
CRE for MAGIC (modular, agile, intensified & continuous) processes
Intensified reactor and process based on work done at CSIR – National Chemical Laboratory (under the Indus MAGIC program).
The focus is on (1) underground coal gasification, (2) safety of nuclear reactors and (3) transforming waste biomass to energy and chemicals. The biomass utilization is the major focus with the aim of developing economically viable modular processes for distributed transformations of waste biomass to energy and chemicals. New ideas and opportunities of harnessing hydrodynamic cavitation for pre-treating waste biomass and for enhancing performance of anaerobic digesters will be investigated.
Harnessing hydrodynamic cavitation for pre-treating lignocellulosic biomass (pre-treatment of rice straw slurry). Efforts have been initiated to develop cavitation intensified anaerobic digester based bio-refinery for modular and sustainable production of energy and chemicals.
Our work on hydrodynamic cavitation will be developed further to make an impact on distributed and in-line effluent treatment strategies. The cavitation can also be synergistically combined with other water treatment strategies like coagulation and adsorption for developing effective water treatment strategies. The work has a significant potential to reduce net water consumption in industries by developing appropriate recycle and reuse strategies.
