Energy and environmental benchmarking using energy intensity indicators provides a common and consistent basis for monitoring, tracking and assessing hydrocarbon processing industry (HPI) performance. These indicators were developed and used during performance audits characterizing two sour gas-processing plants. To establish realistic targets for continuous improvement, three plants were modeled on a process simulator after calibration with actual audit results. Subsequent to this, specific plant aspects were examined and optimized using process simulation techniques. The modeling results were used to formulate recommendations for changes to process equipment and its operation for the
