Prof. Luo He’an Research Group Wins the Second Prize of National Science and Technology Progress Awa
On January 11, the National Science and Technology Award Conference solemnly opened in Beijing. “The Complete Set of Technology of Cyclohexanone Ammoximation Caprolactam Production Process” was awarded the Second Prize of 2009 National Science and Technology Progress Award. This achievement was won by the cooperation of Prof. Luo He’an Research Group of XTU, Baling Branch of China Petroleum & Chemical Corporation, Research Institute of Petroleum Processing of China Petroleum & Chemical Corporation, Hunan Baili Engineering Science & Technology Co., Ltd and China Petroleum Engineering Construction Company. This was the second time for Prof. Luo He’an Research Group to win national award after winning the second prize of 2006 National Science and Technology Progress Award.
The achievement developed a new type of rearrangement reaction process and reactor in the development course of third-level rearrangement technique of cyclohexanone oxime, reducing the acid oxime ratio and raw material consumption and improving the quality. For caprolactam purification, neutralization crystallization process was developed, which realized the effective separation of crude caprolactam and thiamine, improved the quality of thiamine and reduced energy cost. The new turntable extracting tower improved the extraction efficiency of caprolactam; the magnetically stabilized bed hydrogen refueling technology reduced catalyst consumption; Replacing flash evaporation process with pre-distillation technology can remove the caprolactam in the water and light components effectively. Compared to producing caprolactam with HPO process, this technology has some advantages including a short process flow, easy operation, low investment in devices, low production cost and low discharge of “three wastes” per unit product. At present, the complete set of technology has been applied successfully in Baling Branch of China Petroleum & Chemical Corporation, which brought significant economic and social benefits.
