Heat integration as a means of saving energy can be accomplished in a systematic manner using thermodynamically based methods. This paper examines the relationship between the exergy balance and the pinch point procedure to evaluate minimum utilities consumption. As a test case it is shown how these ideas are used to save energy in an existing tomato paste plant. Results indicate that energy savings correlate with decreasing productions of entropy. On the other hand, from a return on an original investment standpoint there is no correlation.
