Designing a total site for an entire lifetime under fluctuating utility prices [Elektronski vir]
Nemet, Andreja ; Klemeš, Jiri ; Kravanja, Zdravko
The reduction of utility consumption within processes significantly contributes to the sustainability of the processes. A widely-used method for decreasing utility consumption is by heat recovery by ...applying Process Integration methodology. Process Integration can be performed at two levels: (i) at the process level, where the heat exchange occurs directly between the hot and cold streams and (ii) at Total Site level, where an indirect heat exchange is mostly performed between hot and cold streams via an intermediate utility. A Total Site consists of various units served by a central utility system. A unit can be any system with heat surplus or demand - production process, residential, business, service, agricultural, etc. Widening the scope of Process Integration increases the complexity of a problem. However, enhanced Heat Integration and economically-viable designs can be obtained by establishing an appropriate trade-off between the operating cost and the investment. Many of the approaches for optimising this trade-off consider current utility prices. However, utility pricesʼ track-record demonstrates considerable fluctuations, with steady tendency for increasing. A stochastic multi-period mixed integer nonlinear programming model for the optimisation of Total Site has been developed by considering forecasted utility prices. Various projections of utility prices have been derived. They use the past utility prices due to the uncertainty of forecasting. The developed approach reflects different utility prices, and attempts to obtain a more realistic design with better economic performance compared to the design based on current utility prices.
