Original Abstract

Industrial sites spend a large quantity of energy and emit into the environment a considerable amount of Greenhouse gases (GHG). Heat recovery and power cogeneration at Site level provide important options for energy saving and emission reduction. In designing and optimising Total Site heat recovery and cogeneration, the base indicators related to heat recovery, cogeneration efficiency and operating costs can be advantageously extended to allow designers seeing the complete picture of the system performance. Such additional indicators are suggested in the current work, including capital cost, as well as GHG and Water Footprints. The case study showed that generating an additional 15 t/h of boiler steam (VHP) beyond the 33 t/h that was initially needed, increased power generation by 1.72 MW (112 %), and lowered key targeted intensity indicators of Capital Cost by 7.7 %, GHG Footprint by 31.6 %, and Water Footprint by 44.6 %. These results demonstrate the dynamic link between the Total Site cogeneration system and the extended indicators.
