On March 2, 2021, good news came from Hubei Sanning Company: the ammonia synthesis and urea production systems of the 600,000-ton ethylene glycol project were operational, and urea was produced at 16:28. Hubei Sanning Shibao Mountain New Materials Branch is located in the Yaojiagang Industrial Park in Zhijiang City, Hubei. The company’s 600,000-ton ethylene glycol production facility is capable of producing 520,000 tons of synthetic ammonia, 520,000 tons of urea, and 600,000 tons of ethylene glycol per year; it began trial production in February 2021. This project uses 6.5 MPa water-coal slurry for gas production; the shift unit is designed to handle a raw gas flow rate of 470,000 NM3/h, making it the largest shift unit of its kind in the world to date. The conversion unit utilizes the complete temperature-control conversion process technology provided by Huashuo Technology Co., Ltd., as well as EB-6 series sulfur-resistant conversion catalysts (a total of approximately 400 cubic meters of catalysts). It was successfully brought online in one go on February 19, 2020; the CO content at the outlet was as low as 0.4%, and all operational parameters met or exceeded the design specifications, thus satisfying the production requirements. Huashuo Technology has carried out extensive optimization efforts in areas such as process flow, selection of supporting equipment, equipment design, overall design, and automatic control. It has adopted temperature-controlled conversion furnaces and related temperature-control conversion process technologies that are covered by independent intellectual property rights; this has reduced the number of operating devices, lowered energy consumption during operation, and improved the reliability of the system’s performance ； A self-heating purification furnace was adopted in place of the traditional main heat exchange process, addressing the issue of difficult temperature control at the inlet of the isothermal conversion furnace ； The use of vertical waste boilers replaces traditional horizontal ones, saving space and investment in equipment, while effectively avoiding the leakage problems associated with the tube sheets in conventional waste boilers ； The automated control scheme of the device was optimized, significantly reducing the commissioning time of the conversion system. This set of extra-large conversion devices achieves smooth, efficient, and stable operation, reaching a level ahead of that in the industry.
