Process Systems Engineering (PSE): Process simulation, process control, process synthesis, large scale process optimization, real time optimisation (rto), CO2 mitigation technologies, automatic moisture control, post harvest grain technology.

  • My major research area is in the development and application of Process Systems Engineering (PSE) technology to industrial plants.
  • Our approach is to work with industry on important practical problems. Our measure of success is whether we can solve a problem that has practical significance and has eluded solution. Over the years, we have worked on joint research projects with several industrial partners. This approach benefits both the industrial and academic sectors. A number of publications have resulted from this work; several are listed below.

Process Systems Engineering

  • The major research thrust that has emerged has been the use and integration of knowledge (in all its forms) to design and optimize the operation of processes at several levels of detail. At the highest level, we are developing computer programs to synthesize or invent process flowsheets using knowledge in the form of experience. At a lower level, we are developing methods to synthesize and optimize the design of special processes, for example, CO2 mitigation processes and thermally integrated distillation sequences. This involves a combination of experience, mathematical models and optimization.
  • My continued research now centres on the development of generalized procedures using available software to integrate the synthesis, simulation, optimization and control functions. For example, we are currently commercial simulation systems for building real time optimisation applications. This involves a tradeoff between speed, accuracy and the ability to update the model with on-line information. Processes that are currently being studied are refinery processes, catalytic distillation processes, biotechnology processes including production of tPa

CO2 Mitigation Processes

  • This research focuses on PSE applications of energy utilisation with a goal to reduce CO2 and other greenhouse gas emissions.
  • Current projects involve the techno-economic evaluation of various CO 2 mitigation strategies including MEA scrubbing, O2 /CO2 recycle combustion, integrated gasification combined cycle (IGCC), fuel cells and membranes.
  • Another major project concerns the development of a new generation of computer models for the synthesize of green house gas mitigation systems. Our modelling framework will have the ability to analyze a fleet of power plants and synthesize an optimal fleet-solution.
  • Our research is involved with a Canadian CO2 Consortium on several large-scale CO2 mitigation options.

Post Harvest Grain Technology

  • An application of PSE technology to Post Harvest Grain Technology has emerged as an interesting and important application. Grain losses due to only to inadequate and poor dryer control have been estimated at about 10% world wide. Our research has led to the development of commercial control systems for automatic moisture control in grain and industrial dryers. For more information on the commercial control system, known as the DryerMaster system, please contact Dantec , Waterloo, Ontario.

NSTDA

  • NSTDA (National Science and Technology Development Agency of Thailand) and the Department of Chemical Engineering at the University of Waterloo have signed an MOU outlining an initiative to promote the training of graduate students. NSTDA and the University of Waterloo currently have several active projects.
  • For Thai students wishing to participate in the consortia with the University of Waterloo there are two basic options:
  1. support by Thai Government Scholarships
  2. support by NSTDA

 

  • In the case of support by a Thai Government Scholarship the student should register as a graduate student at the University of Waterloo. In the case of support by NSTDA the student may choose to register at a Thai University or at the University of Waterloo depending on the research plan and funding available from NSTDA. In either case the student is encouraged to develop a collaborate research program with University of Waterloo professor and a Thai university professor.
