Liquid liquid extraction

Critical Review of CFD Models for Solid–Liquid Mixing: A theoretical review of turbulence models, drag laws, interphase forces, and meshing practices in CFD studies of solid–liquid systems. Critically assessed the validity of the Schiller–Naumann drag model at high Reynolds numbers and solid loadings, and discussed potential extensions based on existing literature. Seminar: Process Systems Engineering in Chemical Engineering – study of dynamic process modeling, microkinetic reaction mechanisms, and advanced process control strategies including nonlinear model predictive control (NMPC)

Completed a well-rounded program focused on core chemical engineering subjects including thermodynamics, fluid flow, heat and mass transfer, separation processes, and process control. Final Year Project: Designed a 1 TPA plant for producing Dimethyl Cyclopropanol, a high-value specialty chemical. Work involved route selection, material and energy balances, equipment design using MATLAB, site selection based on techno-economic criteria, and integration of green chemistry through solvent recovery and waste valorization. Seminar: Design of packed bed reactors for enzyme-catalyzed reactions, covering immobilization techniques, mass transfer, and CFD-based optimization. Electives: Green Chemistry, Sustainable Polymers, Spectroscopy of Organic Compounds, Corrosion Sciences.
