Sustainable Energy Conversion Processes

Research Title
Steel Manufacturing by-product off-gas valorization via system process engineering technologies

Research Objectives
The steel industry faces significant challenges with high greenhouse gas (GHG) emissions arising from the use of carbon as a required reagent in the primary iron oxide reduction step of the steelmaking process. The average CO2 emission rate is 1.9 tonnes for every tonne of steel generated worldwide. Which contribute to about 7% of the total anthropogenic CO2 emission. Moreover, carbon tax has been proposed that CO2 emissions would be taxed up to $50/tonne. This translates to an extra hundreds million per year in taxes. Which has serious implications on the profitability of the business and therefore incentivizes steel refineries to reduce their emissions wherever possible.

In cooperation with ArcelorMittal Dofasco, Hamilton, Ontario, the research objective is to design, simulate, model, and analysis various steel manufacturing off-gas valorization processes. The options of retrofit could be upgrade the present power generation system, synthesize the off-gas into chemical products such as methanol or methane. The profitability, environmental effect, energy cost, reliability will be compared among various options. The final goal of the research is to find the best option that have the lowest cost in reducing CO2 emission from steel manufacturing on the long run.
