With the implementation of policies aimed at controlling energy consumption, as well as strict regulations on carbon emissions, it has become even more important to work towards energy savings and reduced consumption. Dawei Ammonia Production conducted a thorough inspection of the energy-consuming equipment at the facility, and found that the primary water pump in the central water treatment system was operating in a way that resulted in excessive power consumption, as if using a powerful engine for a task that required less power. Taking into account the production process and equipment operation status in the water treatment area, the center has decided to optimize the operating mode of the raw water pumps in order to increase their utilization rate and load capacity. On the morning shift of February 14, the electrical specialist from Baode Station, along with the equipment specialists Feng Qiaoxian and Zhang Hongfang, were contacted to carry out preliminary testing on the 3 raw water pumps. During the testing, when the motor load of Pump No. 1 and Pump No. 2 was at 95.8%, the water supply flow rate was 1700 m3/h; whereas when the motor load of Pump No. 3 was at 98.3%, the water supply flow rate was 1250 m3/h ； After on-site monitoring and verification carried out jointly by the relevant departments, it was concluded that operating only one raw water pump meets the current production process requirements in terms of equipment, electrical systems, and process parameters. After considering various opinions, relevant operating procedures were established; at 9:30 on March 3, the operation was adjusted from two raw water pumps to just one raw water pump (2#). The electrical system and equipment are monitored continuously for eight hours to assess their operational status. During the monitoring period, the motor operated well, with current, temperature, and vibration all within the specified limits. Therefore, as of March 4, the raw water pumps were adjusted to one in operation and two in standby mode; one of the raw water pumps has been operating since that date, and its water supply capacity is sufficient to meet the process requirements, with the equipment performing well. The synthetic ammonia production facility has achieved greater economic benefits while reducing energy consumption, saving 435,600 yuan in electricity costs per year.
