Riipen Rating and Review

You will receive a Riipen rating and review from Ryerson Students' Union for your work on FLUE-GAS EMISSION MINIMIZATION DESIGN CHALLENGE.


LinkedIn Recommendation

The best submission will receive a LinkedIn recommendation from Dr. Huu Doan.


Environmental regulations require that flue-gas emissions (a by-product of energy generation for processes) must be minimized. An ideal strategy for reducing flue-gas emissions may consist of a combination of:

  • Alternative Fuel Sources,
  • Modifications to the utility system,
  • Modifications to the process system,
  • Efficient Heat Recovery/Cogeneration, and
  • Pre-/Post- Chemical Treatment.

The design development of such a site utility system must be done at minimum cost (i.e., minimal capital investment and minimal operating costs). Novel designs and/or retrofitted existing designs may be developed.


Create a 5-6 slide PowerPoint deck outlining your solution(s). Justify your solution(s) and claim(s).



Some of the typical pre-treatment methods for fuels are:

1) Removal of hydrogen sulphite (H2S) in natural gas before it is used in power generation since hydrogen sulphite turns to sulphur-containing flue gas after its combustion in a burner.

2) For coal power generation, coal is usually treated to remove most of its sulphur content before being used in power generation. As a result, the concentration of sulphur (in the form of SO2) in the flue gas is reduced.

For post-treatment after combustion of fuel in a burner of a power generation process, the most popular method is gas absorption. In this process the flue gas is passed through a packed column (entering the bottom of the column) where it is in contact with a liquid, and the flue gas (SO2) is absorbed into the liquid, leaving the clean gas to go out of the top of the packed column.

Other Submission Details

Until further instructions are provided, please send submissions or questions to Monica Kwong at mkwong@rsuonline.ca. Questions will be compiled every other day and will be forwarded to the challenge lead, Mohammed-Deq Sabriye, and/or Dr. Huu Doan.

Please submit your project through your Ryerson email and include your student number on your project.
