Description of Research Interests

Dr. Gupta’s research interests are in the area of process modeling and simulation. He has collaborative partnerships for research in the areas of FCC modeling, RD modeling, heterogeneous kinetics and reactor design, CO2 adsorption, heat transfer enhancement, RTD modeling of industrial systems, low cost membranes, waste-water treatment, source apportionment of air pollutants.

The modeling aspects of FCC process are quite complex. The various works reported on different aspects of this process are required to be included and assessed in detailed models. CFD models with UDFs are to be assessed for their predictive abilities and design improvements. RD (reactive distillation) offers many economic advantages over the conventional reaction step followed by distillation. RD and RDWC can save lot of energy and equipment cost in industrial applications. However, there are design complexities. For these processes, user­defined models are needed to accurately predict the process behavior.

Modeling the kinetics of heterogeneous solid catalyzed reactions and estimation of the kinetic parameters. In certain situations, like, in a slurry reactor, two immiscible liquid phases come into existence after some initial reaction time. Modeling of the kinetics of such reactions and predictions of rate constants is important for suitable reactor design.

Heat transfer studies in modular heat exchanger configurations (conical, semi­circular). Conical configurations are expected to give more heat transfer than the straight tube heat exchangers due to secondary flow, but at the expense of more pressure drop. Semi­circular heat exchanger configurations are attractive options as the size of heat exchanger becomes compact requiring less space and material and useful for novel designs. The heat transfer studies from such configuration would help in developing such novel heat exchangers.

RTD measurement using radio­tracers, and diagnosing the anomalies in the process equipment in industrial and lab scale operations. The RTD concept can be used for fault diagnosis of the industrial equipment in real time without the need of shut­downs, which causes production loss.

Modeling the CO2 adsorption on tailored adsorbents. The adsorbents work on the principle that CO2 is weak acid that can be trapped onto a solid modified to have a tailored pore structure to create a large surface area for capturing CO2. Mathematical models can be used to predict fixed­bed adsorption. Modeling source apportionment for particulate matter in ambient air and the effect of crop residue burning (CRB) on air quality. Receptor models are extensively used for quantification of source contribution. Chemical mass balance (CMB) receptor model consists of a solution to linear equations that express each receptor chemical concentration as a linear sum of products of source profile abundances and source contributions.
