Total Site heat recovery offers considerably high potential for energy saving. It provides additional degrees of freedom for heat recovery and cogeneration. A key issue in Total Site heat recovery is to select the minimum allowed temperature difference specifications on a site to enable obtaining realistic and useful heat recovery targets for the individual processes and the entire Total Site. A discussion covers the additional components enabling the estimation of the tradeoff between heat recovery and capital cost targets for Total Sites - the evaluation of the capital costs for the generation and use of the site utilities; construction of the Total Site Profiles and Site Utility Composite Curves; identification of the various utility generation and use regions at the profile-utility interfaces of the curves; identification of the relevant enthalpy intervals within those interfaces; estimation of the required minimum heat transfer surface area performed alongside the minimum required number of utility generation and utility supply heat exchangers. This is an abstract of a paper presented at the CHISA 2012 - 20th International Congress of Chemical and Process Engineering and PRES 2012 - 15th Conference PRES (Prague, Czech Republic 8/25-29/2012).
