A method for faster application of process integration techniques in retrofit situations

Numerous process integration techniques were proved to be highly effective for identifying and estimating potential energy savings in the industry. However, they require high time effort collect analyse data. As a result, do not constitute common practice industry opportunities increasing efficiency of industrial processes are missed. The paper presents method, termed “ Energy-Saving Decomposition ”, which is based on Process Integration techniques. It intended expeditiously outlining promoting Two screening tools, mathematical criteria engineering experience, employed reducing problem dimension before applying conventional design procedures. first step disregards streams their contribution overall energy-saving potential, calculated utilising novel decomposition technique. most promising network then selected its size. second reduces complexity further, employing economic considerations. This method was exemplified by application dairy factory: outcomes itself compared Pinch Analysis results showed that developed can simplify reduce consumption methods significantly, while encouraging saving opportunities. automatic algorithm allowed size from 62 existing plant 22 requiring computational only 135 s. final retrofit proposed same obtained with Analysis, achieving 23% reduction consumption. • A expeditious studies presented. allows case study proves reduced no loss favourable options. automated fast compute, few minutes.
