Abstract Development of sulfuric acid production method has taken us to commercial use of contact process in most industries. However, most plants still
utilize coolers and steam generators to divert the excess heat. This method of energy recovery is inefficient, thus, this study attempts to redesign
commercial heat exchanger network for better efficiency and lower cost. Process integration using composite curve, cascade diagram, heat
exchanger network alternatives, completed with improved plant flow diagram are successfully calculated and analyzed by HINT software. Total
energy saving can reach up to 74.70% and this results in total cost saving More >
