This motivates to do energy efficiency. Sulfur-iodine cycle process is an important part because it is the last process to produce H 2. Some equipment units and utility units that exist in the process system require and produce substantial energy. It is found that some usage of energy systems can be optimized through the process of energy efficiency analysis using pinch analysis. In this report, HINT software was used to conduct the pinch analysis with variations in the minimum temperature approach (ΔTmin). Analysis results showed that at ΔTmin 10 K, high maximum energy recovery (MER) and the lowest total H 2 production cost could be obtained.
