| Abstract: | Some calculations are made for the utilization of waste heat in the tail gas from preneutralization,pipe reaction and secondary ammoniation sections.The annual steam cost of 1.38 million RMB Yuan can be saved with the investment of 1.60 million RMB Yuan and the return within 14 months for heat exchanger system,when the waste heat is used on the vaporizer instead of steam for vaporizing liquid ammonia to supply gas ammonia of preneutralization reaction. |
