Optimal transition of petroleum refineries to achieve decarbonization objectives

Decarbonization of Indian petroleum, petrochemical, and gas processing refineries is essential to achieve national climate change mitigation (greenhouse gas reduction) targets. This will require adoption of technologies such as carbon capture and sequestration and use of blue hydrogen. Selection of the appropriate technology will depend on the decarbonization potential, cost, scalability, and technology readiness level.

Integrated design and control of batch heat exchanger networks

Energy integration in batch processes is tricker, as compared to their continuous counterparts, due to additional time constraints. Previous work has shown that sequential design and control can lead to suboptimal performance during operation. This project aims at developing a simultaneous design and control framework for such networks. 

The project is simulation-based and experience with Matlab/Python will be beneficial.

Battery management system for electric vehicle and drone application

Fire hazard in electric vehicle is one of the key problem that requires immediate attention. One of the way to prevent such fires in battery systems is have a competent battery management system which can predict the potential failure of the battery pack. Battery management system (BMS) consists of battery model, parameters and state estimation algorithms and optimziation toolboxes. Traditionally, circuit based models are being used in these BMS which do not provide physical understanding of the battery systems.

Nutraceutical Purification Using Simulated Moving Bed Chromatography: Design, Optimization and Control

SMBC is an implementation of continuous chromatographic separation, which involves solid stationary and fluid mobile phases. SMB is increasingly being used to convert pharmaceutical batch separations to continuous owing to the advantages of higher productivity and lower use of solvent. Use of  SMB for purification of herbal active ingredients has not been reported, since the precursor extract is derived from natural resources and hence represents a complex mixture with large number of components.

Molecular Simulation Study of Natural Products: Separation & Applications

Both Monte Carlo and molecular dynamics simulations will be performed in this proposed study using open source software packages MCCCS Towhee and GROMACS respectively as well as in-house codes, for post-processing of output data.

Computer-aided molecular design of new, non-traditional solvents is also part of the overall computational scheme.

Electrocatalytic CO2 reduction reaction: Multiscale modelling of transport, catalyst surface evolution, and reaction processes

According to the Paris climate accord signed in 2016 with the aim of substantially lowering the risks and impacts of climate change, the goal is to pursue technologies that can limit the rise in average global temperature to ~1.5 degree C above the pre-industrial levels by 2050. One of the important greenhouse gas emissions being targeted is carbon dioxide. Currently, production of commodities crucially linked to growth and development, such as cement, steel, plastic, ammonia and aluminum, are resulting in large CO2 emissions.

Molecular scale understanding of ionic transport and reactions inside a fuel cell and batteries

The focus of this project is on molecular scale understanding of transport processes and reactions in fuel cells and batteries. Student working on this project will learn about state-of-the-art techniques to study determine the mechanism and rate constants for these processes.

Design of robust optimal heat exchanger networks

Heat exchanger networks are designed with an aim of optimal performance at the design steady stage. This does not guarantee that in the presence of unanticipated (temperature, flow, UA) and planned (temperature, flow) disturbances, the designed network will still be optimal. To this end, this project aims at designing a network which will be robust enough to tackle these disturbances while maintaining optimality of operation. Continuous as well as batch heat exchanger networks will be targeted.

Design aspects of energy-integrated batch distillation

Distillation is one of the most commonly used as well as the most significant contributor of energy in chemical processing complex. Energy integration can improve the sustainability of the process by reducing utility requirement in batch distillation. However, operation of such columns is challenging. Traditionally, design of such systems is pursued without giving any consideration for operation. In the light of this, this project aims as developing a design framework for such distillation columns to address operational challenges.
