Process integration with combined heat and power

Combined heat and power (CHP) systems have the potential to be used widely in many areas of industry and services as a powerful energy conservation tool. The design optimisation tools and software developed during this project for process integration with CHP, constitute a major breakthrough in energy conservation.

Process integration technology i.e. Pinch Analysis, and in particular its extension to the total site, has proved to be a very successful tool for energy saving. CHP systems offer considerable application potential in many areas of industry as an energy conservation tool, but they must be applied in the most effective way if their energy saving potential is to be maximised. The objective of this project was to develop a new methodology, supported by appropriate design tools and software to produce a major breakthrough in energy conservation through the process integration of CHP. Energy saving potentials through in industry are huge, possibly as much as 30% in the food and drink industry and 10% in the main process industries such as chemicals and petrochemicals. In absolute figures energy savings in the range of tens of thousands of MW are possible in both industry and the energy generation industry. Another specific area where this project aimed to offer solutions is the current application of heat pumping techniques for large industrial separation plant. A systematic procedure for designing heat pump assisted separation and its integration into CHP systems was further developed and tested against industrial applications. It is anticipated that energy savings of up to 35% may be achieved.
