R&D Areas/Projects

  • Development of efficient strategies to model and simulate various petroleum engineering processes (primarily, staged separation processes, and processes having reactive systems) have been of interest to me always. In staged separation processes, the recent trend is more towards installing packed columns, and revamping the existing staged columns for improving their separation efficiency and minimising the operating costs. Energy recovery through Heat Integration of processes has always been important to process engineers. However, with ever increasing costs of fuel and utilities (and their limited availability), systematic procedures are now very much needed to analyse an existing design using a thermodynamic approach which could enable the designer/process engineer to come out with process schemes that will be more energy efficient. Processes which involve highly exothermic reactions, if properly Heat Integrated, can tend towards Zero-Energy Processes. In this direction, research work on use of Exergy Analysis for an Ammonia Plant, a Sulfuric Acid Plant, and Refinery Columns has been done by my students.
  • Energy analysis of distillation columns for improving their performance, and for exploring the possibilities of a systematic process integration, has been a subject of my research in collaboration with Prof. U.V. Shenoy (Ex-Professor, IIT Bombay).
  • Over the past several years, a dedicated simulator called AmmSimTOP has been developed by my group at CAD Centre which includes rigorous models for practically all the units encountered in a typical Ammonia Plant [Reformers, Shift Converters, Synthesis Converters (of various types), Carbon di-oxide Absorption-Regeneration Systems, Purge Gas Recovery Units]. The simulator has been customised and delivered to several Ammonia Plants operating in India. A dedicated simulator for Urea Plants (fluid handling section only) has recently been developed by my team using rigorous models of key units and thermodynamic procedures. Efforts are on to enhance and strengthen the capabilities of these two simulators.
  • Other areas in which I am interested in pursuing research work are Computer Aided Process Engineering (Data Modelling, in particular), On-line Optimisation Strategies, and Optimisation Algorithms for sequential and simultaneous simulators.
  • Throughout my professional career, I have worked extensively in the area of CAPE (Computer Aided Process Engineering).  At IIT-Kanpur, I had undertaken software development projects for several companies in India. At EIL, I was actively involved in the development of In-house Process Software for the company and provided simulation support to the Process Division engineers. At IIT-Bombay, I have guided and supervised software development work for several projects from the Process Industry including Refineries, Petrochemical Complexes, and Chemical companies. The CAD Centre of IIT-Bombay has developed dedicated Steady-state rigorous simulators for Ammonia and Urea Plants under my supervision, and these are being used extensively by many companies in India. I have been a consultant (as Retainer) to several process software development companies in India in the past. The areas in which I have provided support to the Indian Industry include Applications of mathematical modeling, simulation, design, and optimization techniques for Energy and Process Integration; Process Intensification in Refineries and Petrochemical Plants; Separation Processes including Reactive Distillation, Design Verification. I have extensive hands-on experience with process simulators including Aspen Plus, PRO-II, ChemCAD, Design-II, and HYSYS (now called Aspen Hysys) and have trained several hundred process engineers (working professionals) in the area of process simulation.
