Dr. Parham Mobed

Research Interests

My research focuses on synthesis and optimization of multicomponent distillation configurations. Feasible configurations constitute a vast search space that makes finding an optimal configuration a challenging problem. Of these feasible configurations, we are interested in operable configurations with minimum heat duty, capital cost and exergy loss. I am currently working on developing methods and algorithms for solving these nonlinear programming problems to global optima, and consolidating them into a user-friendly interface that can be used by industrial practitioners.​

Zheyu

Zheyu Jiang

Research Interests

My research interest lies in developing new methods and algorithms to synthesize and optimize multi-component distillation systems. In particular, I have been working on developing nonlinear programming based global optimization algorithms for multi-component distillation configurations to minimize their total costs and to maximize their thermodynamic efficiencies. These algorithms and methods will greatly benefit industrial practitioners designing highly energy efficient and cost effective distillation systems for a wide range of applications.

Krishna

Radhakrishna Tumbalam Gooty

Research Interests

My research involves identification of optimal basic distillation column configuration to separate an n-component zeotropic mixture. This is achieved by formulating the problem as a Mixed-Integer Nonlinear Program (MINLP). This formulation is very useful for mixtures with five or more components, since the search space of configurations for these mixtures is very large.
