The field of applied chemistry deals with manufacturing chemical products that involve high temperatures and pressures, and corrosive process fluids. It is necessary to build factories, design equipment, and maintain them. While getting a picture of the process as a whole, after getting an understanding of design theory for factories operating under these special conditions, employees are needed not just for designing equipment, but also for receiving equipment, and maintaining and managing it. The instructor will lecture on topics that involve equipment materials in actual factories as well as these kinds of approaches, with students learning in particular through exercises and problems.
[Objectives] By taking this lecture, students will gain an understanding of material mechanics including the plastic zone, necessary for designing chemical equipment that handles high and low temperatures, high pressure and vacuum, or corrosive chemicals. Students will also learn approaches to thermal stress and fracture mechanics. Based on that, students will gain an understanding of design methods for thick cylinder containers, etc., approaches to partial yielding, and approaches to time-dependent fracturing. Students will also learn approaches necessary for corrosion resistance and maintenance, as well as approaches to design, manufacturing, and maintain actual chemical equipment, through a variety of topics on materials for chemical plans.
