This course will look into various types of process reactors; how they are categorized, what they are best suited for and the constraints. It will also go through the general design principles for most reactor types of which one of the most commonly will be adopted (e.g. stirred tanks) for in-depth studies. The class will briefly touch on other key industrial design considerations such as operability, scalability, safety evaluation, ease of maintenance, control strategies, capital and operation cost implications.
