Process engineering is a branch of engineering science that deals with planning, operation and control of physical, chemical and biological process that processes undergone in industries. Process Engineering is common to all industries. This engineering group has the responsibility to control and optimize the process in any concern.
Process engineers apply their technical skills for satisfying the need of the customer, by designing the best process practices that convert the raw materials into the desired products. They are also involved in research. They create block diagrams, P&IDs, PFD, which are the benchmark for the other engineers to design the overall activities that any industries must have.
The main aim of this course is to make the student understand the technical concepts. This will enhance their skills with practical experience. This course will help the students to acquire knowledge on process control engineering concepts with lots of practical and computer aided problems for the better understanding.
