Abstract: The cleaner chromate production process using sub-molten salt has been successfully simulated using METSIM in order to evaluate the mass balance, energy consumption, heat utilization efficiency, and other conditions necessitated for the process scaling up. Based on the simulation results, the mass and heat balances of each operation unit are obtained, providing valuable reference for the process design. Furthermore, the heat exchange network optimization using pinch technology is performed, enabling the reduction of the heat and cool energy consumption by 31.5% and 31.7%, respectively, and increase of the total energy efficiency by 11.0%.

Key words: sub-molten, process of chromate, METSIM, process simulation, pinch point technology, heat exchange network
