Learners enrolled: 912   |  Exam registration: 65
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. 
INTENDED AUDIENCE : 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.
