Another report on the continuous stable operation of Shandong Alliance Chemical’s DC-C DN2500 ammonia synthesis tower for three years
Thread Content
Recently, another inspection was conducted on the DC-C DN2500 ammonia synthesis system manufactured by Nanjing Jutuo Chemical for Shandong Shouguang Alliance Chemical, and a comparison was made with its performance when it was put into operation three years ago (early November 2012); the tower is operating stably. Some indicators have seen little change. The temperature of the water used for cooling the heat exchange reactor is relatively low, at around 66 degrees, which indicates that the heat recovery performance has remained good ； System pressure is low: ~19 MPa (production ~900 t of ammonia per day, 18.75% methane in the system)
Congratulations on the continuous improvement in the quality level of domestic production of this device. Another important aspect is that the companies in the Shouguang Alliance have a high level of staff competence and employ standardized management practices.
Lu Jian, the chairman of Nanjing Jutuo Chemical Company, comes from Anchun Company. The system in Shouguang is quite good. May I ask where the ammonia synthesis catalyst comes from?
Zhejiang University of Technology A301 ammonia synthesis catalyst, with most particles having a size of 1.5~3.0 mm
Jutuo Company failed miserably on a project at Jinmei Hengsheng involving the replacement of internal components and waste boilers in a synthesis tower. I heard it caused losses of tens of millions of yuan to the company.
