The purpose of this study was to evaluate the energy conservation potential of a heat pump in an industrial site. The proper placement of the heat pump was based on the principles of Pinch Technology. Chevron`s refinery at Port Arthur, Texas, was selected as the industrial site for this study. Two energy conservation options were identified for this site with a combined total savings of $570,000 per year. This represents over 10% reduction in current thermal energy consumption of the process units, which were part of this study. The details of each option are described. The first option was a passive heat integration scheme. The second option involves a semi-open cycle mechanical vapor recompression heat pump that compresses the steam generated from the reactor exhaust streams of the cyclohexane unit to provide part of the reboiling duty of the benzene column
