Performance testing of Lutianhua urea synthesis unit after major maintenance

Thread Content

From 8:00 on January 21, 2026, to 8:00 on January 23, 2026, the ammonia synthesis and urea production units as well as the packaging systems successfully completed their performance tests following the major maintenance. Based on the design standards for performance testing, the advanced levels in the industry, and the energy consumption benchmarks for the company’s production facilities by 2026, the system evaluates the load, operating conditions, and consumption of these facilities. It also conducts statistical analyses and comprehensive evaluations of data related to production capacity, achievement of target outputs, and energy consumption. Lutianhua’s urea production unit/synthesis unit began its major maintenance on December 4, 2025. At 17:00 on January 7, 2026, the thermoelectric coal boiler was connected to the steam system; ammonia began to be produced from the second synthesis tower at 17:50 on the 9th; and successful first-time discharge of urea was achieved at 17:39 on the 10th. The main production units for urea production resumed normal operation. Lutianhua Synthetic Diammonium Urea Plant is one of the 13 large-scale fertilizer production facilities introduced in the 1970s. The plant uses natural gas as a raw material to produce synthetic ammonia via the Kellog process, and urea via the carbon dioxide stripping process. After the capacity expansion, it can produce 1,500 tons of synthetic ammonia and 2,000 tons of urea per day.
