Abstract
Energy management techniques are important topics for continuous searches and studies looking for energy crisis solutions. Energy consumption has an effective role on economic growth of any country. Heat Exchanger Network Synthesis (HENS) is the most successful technology for industrial energy conservation where it guarantees least fuel combustion and so on least harmful gasses emissions. In this work, we formulated an integrated methodology for HEN designs coupled with insulation applications to maximize energy recovery and minimize energy losses. This methodology has been applied on a case study using several types of insulations as (Mineral wool, Cellulose and Aerogel).With help of the mathematical solver software (GAMS); we got alternatives designs for revamping the case study. Coupling between HEN design and insulation applications reduced fuel combustion, this reduction has two positive effects. Firstly minimize operating cost and secondly reduce emissions to protect environment, where the revamped design realized reduction of cost and emissions reached to 60% compared with existing unite. Other suggested modification for revamped design was replacement fuel oil with natural gas. In this case the revamped design achieved best results of minimizing cost and emissions, reached to 80% less than existing case rates.
