Objective:

This course will enable the participants to Learn the techniques of heat exchanger network synthesis Learn principles of optimization of processes by energy and resource analysis. Learn how utility cost can be minimized

Description:

Improving performance of a chemicals manufacturing facility is an ongoing process that must continue throughout the life of the plant. Efficient use of heat can reduce the energy consumption which in turn reduces manufacturing costs. Networking of heat exchangers is a technique by which use of external utilities like, steam, cooling water, hot oil, chilled water, chilled brine etc., can be minimized. This can be achieved by exchanging heats of hot/cold of process streams with each other. Network design methods are simple to understand and implement. Their main advantage is that they can be deployed prior to equipment design stage using only the process stream data. These methods can also be used in existing running plants under certain operating constraints. The network design provides optimum numbers and locations of heat exchangers within the processing train. While designing the network, the optimization criteria used could be – minimization of external energy usage, minimization of heat transfer area or minimization of total annual cost. This course also presents an example of optimization of number of effects of a multiple effect evaporator using the principles of optimization of processes by energy and resource analysis. While the course presumes that the attendees possess Chemical Engineering background, other engineers from Process industries would also find the course useful.
