Research Statement


Separation Science is crucial for the advancement of chemical process technology, particularly in Carbon Capture & Storage (CCS), Direct Air Capture (DAC), Net Zero Hydrogen (99.999%), Recovery of Monovalent ions and the removal of trace-level contaminants. Despite the availability of conventional materials, like, zeolites, alumina, activated carbon, and carbon molecular sieves, industries are still in the early stages of implementing environmentally friendly technologies for cleaner energy and water management to attain sustainability goals. Moreover, we are significantly behind in achieving the Net Zero targets set by the Intergovernmental Panel on Climate Change (IPCC), as well as meeting the water quality standards outlined by the World Health Organization, particularly concerning the treatment of emerging contaminants for sustainable water management
This gap can be addressed by synthesizing advanced porous materials, such as Metal Organic Frameworks (MOFs), Layered Double Hydroxides (LDHs), and Zeolitic Imidazole Frameworks (ZIFs), and validating their performance of separation processes at the lab scale. However, challenges lie in ensuring the selectivity, stability, and scalability of these materials under various real-life conditions, especially when transitioning from microgram to kilogram-scale process demonstrations. These challenges are further amplified when dealing with low concentrations, as in DAC and emerging contaminants. Therefore, performing these experiments with precision is a unique characteristic tool and being able to develop actual processes from them is the most tangeble output.
Having worked with both sides (academia and industry collaborators), my expertise in this domain could be able to bridge this gap, as the key insights gained from materials synthesis, experimental characterization and design of instrumentation test rigs is valuable in developing pilot and industrial-scale designs to the industrial collaborators. The data obtained will also aid chemists, computational researchers, and process engineers in tuning material properties and exploring the option of developing new systems or integrated separation processes for enhanced productivity. In short, the convergence of material science and process engineering is the key for advancement of Applied Research in Energy & Environmental domain. The following schematic represents the outline of my research statement.

Current Projects

Design and Development of Structured beds for Direct Air Capture

This research investigates the performance of structured bed in selective removal of CO2 from direct air capture (400 ppm) under dry and humid conditions. Besides exploring the practical application, understanding the interplay of fundamental aspects, like, mass transfer and dispersion on Process KPIs is of high priority.

Mixed Matrix Modules for Post Combustion CO2 capture

This research aims towards the design of steam-TSA cycle for adsorptive separation of CO2 from simulated dry and humid flue gas compositions. Besides, the current study also address the comparison between a packed bed and a structured bed.

Adsorbent Screening for Blue Hydrogen

The major focus here is to develop a suitable adsorbent that attributes to linear CO2 isotherm with greater working capacity between 15 to 1 bar. The idea here is to promote the generation of blue hydrogen which can later be used as a fuel.

Amine based Inorganic Sorbents

The idea here is to understand adsorption of CO2 on amine sorbents grafted on to different substrates over a wide range of humidity to explore the co-operative mechanism at different temperatures.
