Core Viewpoint - China National Chemical Engineering's subsidiary, China Five Rings Engineering Co., has developed a "second-generation high-efficiency synthesis, low-energy consumption urea process technology" that has been recognized as internationally leading by the China Petroleum and Chemical Industry Federation [1][5]. Group 1: Technology Innovation - The new generation of full condensation reactor and high-pressure loop process has achieved the synthesis of urea through two-step reactions under optimal conditions, significantly improving conversion rates and reducing steam and circulating water consumption, thus overcoming the energy consumption bottleneck of traditional urea plants [6]. - The technology has been implemented in over 30 sets domestically and internationally, with a total capacity exceeding 25 million tons per year [6]. Group 2: Performance Metrics - The urea plant built based on this technology at Anhui Haoyuan Chemical Group has a capacity of 700,000 tons per year and demonstrated performance exceeding design values during a 72-hour on-site assessment, with steam consumption for urea production at 562.9 kg per 2.5 MPaG, reaching industry advanced levels [6]. Group 3: Recognition and Awards - The second-generation urea process technology has received multiple accolades, including the Hubei Province Patent Gold Award and the First Prize for Technological Progress from the Nitrogen Fertilizer Industry Association, along with 22 national authorized patents, of which 7 are invention patents [6].
