Equipment Design: Mechanical Aspects


Chemical process plants include a number of important equipment such as reactors, distillation columns, absorbers, heat exchangers, evaporators, crystallizers, etc. Design of such equipment should be carried out a priory to set-up a process plant and thus, it is basic step in a chemical process. Mechanical design of equipment addresses the stress and strain produced in different parts of the equipment such as shell, head, support, etc. due to operating conditions of the process. The success and failure of the process depends on how perfectly stress and strain are considered while designing. Thus, the present course enables one to learn about the mechanical design of chemical process equipment.

Undergraduate students. However, this course will also be helpful for those who have substantial industrial experience while working in chemical processes and designing process equipment.

The instructor is working as Associate Professor in Chemical Engineering Department of IIT Roorkee. She has completed B.Tech degree from AMU Aligarh, Aligarh in 2000 and M.Tech and Ph.D. degree from IIT Roorkee in 2002 and 2007, respectively. Her major fields of study are Process Integration, Energy and Mass Conservation and Modeling and Simulation of Chemical Processes. She has almost 10 years experience in teaching and research. During this period she has supervised 3 Ph.D. and 19 M.Tech. theses. At present 5 Ph.D and 3 M.Tech theses are in pipe line. I have published 29 and 28 research papers in different refereed journals and conferences, respectively. I have taught the proposed course six times in my 10 years teaching career.
