| Abstract | Application of pinch technology to the US industries in an early screening study has identified potential for heat pumps in several of the industrial sectors. The site selected for this study is Kerr-McGee Refining Co. in Wynnewood, Oklahoma and the participating utility is Oklahoma Gas and Electric Co. The objective of this study is to further identify the energy savings potential through advanced heat pumps and other energy conservation methods developed in the context of pinch technology. Three units: hydrocracker, deisobutanizer and splitters were selected for this study. Three energy conservation retrofit options as described below, are identified with a combined total savings of about $493,930/year in a payback period of 2.2 years. These savings represent from about 44% reduction of current energy consumption of all the three units. The hydrocracker does not provide a good opportunity for heat pumping; however, it has good potential for heat exchange. The heat exchange option calls for increasing the process interchanger area in the hydrocracker unit by 3079 ft{sup 2}. The splitters provide a good opportunity for heat pumping. The splitters' semi-open cycle (mechanical vapor recompression) heat pump option compresses the overhead vapors of the 100W splitter and condenses it to partially supply the heat for the {number sign}2 splitter reboiler. The second heat pump opportunity was identified in the deisobutanizer unit. This mechanical vapor recompression heat pump compresses the overhead vapors of the deisobutanizer and condenses it to completely supply the reboiler duty of the same column. 20 figs., 16 tabs. |
