Shandong Alliance’s new 600,000 tons/year ammonia synthesis system brought online successfully. Author/Source: Modern Coal Chemical Industry. Date: November 19, 2019. Clicks: 122. After a two-year construction period, Shandong Alliance Chemical Co., Ltd.’s “Project for Clean and Efficient Utilization of Coal” was officially put into operation recently. Good news has arrived from the Shandong Alliance site today: the DC-type ammonia synthesis system software package provided by Nanjing Jutuo Chemical Technology Co., Ltd. for this project, along with the patented DC-D-type ammonia synthesis towers, have been successfully commissioned, with production volumes and product quality meeting the specified standards from the very beginning. Currently, the hourly ammonia production exceeds 80 tons, the ammonia purity is over 18.3%, the tower pressure drop is less than 0.25 MPa, and the system pressure is below 13.0 MPa. It has set the current record for the operation of ammonia synthesis systems. The image shows the DC-type ammonia synthesis system. It also shows a screenshot of the DCS interface at 95% load. This technology is another set of key technologies and core equipment with independent intellectual property rights, developed by Nanjing Jutuo Company through its long-term commitment to innovation and continuous research, building on its experience in implementing various ammonia synthesis process systems and technologies in China. The ammonia synthesis reactor in the system was entirely designed independently. The patented design incorporates innovative process and equipment structure concepts during manufacturing; the process makes use of indirect and efficient heat exchange, parallel heat diversion for temperature regulation, as well as quasi-radial gas flow ； Structurally, it mainly features a “three-bed four-section” catalyst basket, a split design, and a bottom-discharge catalyst structure ； The tower adopts a structural and technological design based on the advanced concept of forced heat transfer using impact rod high-efficiency heat exchange tubes; the catalyst basket walls utilize a multi-layer catalyst retention technique. High resistance to hydrogen corrosion materials are used, along with a special design tailored to the characteristics of domestic catalysts. Precise manufacturing processes are employed to continuously improve product quality, resulting in the desired outcomes and complete success.
