Abstract

This paper deals with selection of optimum amount heat to be recovered during Total Site integration and utility targets for external heating, cooling, refrigerating etc. The methodology provides the calculation of minimum capital investment during heat integration of industrial site. It uses heat transfer area targets, utility distribution with overall cost of retrofit. Heat transfer area is calculated for different regions with use of intermediate utility and direct heating and cooling. Minimal temperature difference between Total Site profiles is analysed. Minimum of total heat transfer area for Total Site recovery is calculated for array of minimal temperature differences. The utility consumption, numbers of units and material of equipment are analysed too and minimum total cost for retrofit project of site recovery system is calculated. The case study shows heat recovery improvement on 1.94 MW. Site heating demands is reduced on 37.3 % and cooling capacity reduction is 39.6 %. The implementation of retrofit EUR 777, 474 and payback time is 11.96 months.
