| Abstract: | Based on the high energy consumption of product cooling system in 400 kt/a DAP plant, the technical transformation is taken including process optimization and variable frequency drives for fan. After the transformation, the power consumption of product cooling system is decreased by 1.422 kW. h/t and coal consumption decreased by 3.4 kg/t, the cost of equipment maintenance is reduced, the total benefit of transformation is 1.54 million RMB Yuan per year. |
