The groundbreaking ceremony of CR Power Shenshan Company's 4×1000MW Denitration Liquid Ammonia-to-Urea Conversion Project was held in October 10. After the Project is completed, the ammonia gas for denitration of the 4 units will be completely supplied by the urea hydrolysis system, and there will be no liquid ammonia storage system in the factory, which can completely eliminate the major danger source of storing liquid ammonia in the factory and promote the improvement of safety production level of Shenshan Company.
