Total Site Analysis

Pinch analysis can be applied to an entire production complex consisting of factories that incorporate several processes by determining the site utilities as an integral part of the production processes. Here, the site utility system is used to achieve heat recovery between the processes. This differs from conventional application of pinch analysis, which normally deals with heat recovery within individual processes. An important benefit now reported of total site analysis compared with the conventional approach is a much better relationship between the energy saving and the reduction of CO2 emissions, often from about 40% to nearly 100%. This occurs because the utility system is now involved as part of the heat recovery scheme, ...
