A Practical Approach to Process Analysis and Improvement for Energy Conservation

A practical approach to process analysis and improvement for energy conservation has been developed by establishing the required technical basis, which arises from the first and the second laws of thermodynamics. As the tool for process analysis for the present purpose, the so-called heat availability diagram has been used. It is useful to show visually the status of energy utilization, the loss of available energy due to irreversibility of process, and the bottleneck on improving energy utilization. Several practical examples are taken up for illustrative purposes
