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 efficiency. These algorithms and methods will greatly benefit industrial practitioners in 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 energy efficient distillation column configuration and optimal operating conditions 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.
