Thread Content

The air separation turbine for the Jiujiang Xinlianxin 60·52·40 project was successfully started up. According to Jiujiang Xinlianxin, at 23:22 on October 19, 2020, the second turbine of the Jiujiang Xinlianxin 60·52·40 project was brought online; At 18:56 on October 24, the startup of Turbine No. 1 was completed. During the startup process, technical parameters such as the temperature of the turbine oil and bearing displacement were within normal ranges, and all interlock logic systems of the unit functioned properly. This marks the successful first start-up of the turbines for the two 80,000 cubic meter air separation units in the Jiujiang Heart to Heart 60∙52∙40 project. The successful prime motion of the turbine laid the foundation for the full-scale joint commissioning of the air separation unit. The Jiujiang Heart to Heart 60∙52∙40 project is overseen by Jiangxi Hangyang Gas Co., Ltd., a wholly-owned subsidiary of Hangyang Co., Ltd., which is responsible for the construction, operation, and management of two air separation units with a capacity of 80,000 m3/h each. The Jiujiang Xinlianxin 60∙52∙40 project utilizes multi-nozzle gasification from East China University of Science and Technology, Casali’s low-pressure ammonia synthesis at 15 MPa, Stamicarbon’s improved CO2-stripped urea production technology, and synthesis of methanol at 5.5–6.0 MPa; methanol is then dehydrated to produce dimethyl ether. The plant has an annual production capacity of 600,000 tons of synthetic ammonia, 520,000 tons of urea, and 400,000 tons of dimethyl ether.
