On December 10, 2022, the installation of the first large-scale equipment for the urea production unit in the Shandong Jinmei Mingshui Chemical Project – the urea synthesis tower – was successfully completed. The urea synthesis tower is the core equipment of the urea plant; it weighs 234 tons, has a diameter of 2.8 meters, and a height of 20.37 meters. The lifting method used this time was the single-crane delivery approach, with an 800-ton crawler crane serving as the main crane and a 450-ton crawler crane acting as the auxiliary crane. Before the lifting operation, the project department organized technical personnel and lifting workers to conduct a thorough discussion of the lifting plan. It also carried out inspections and preparations in the lifting area in advance, and ensured that all technical and safety requirements were properly communicated. During the lifting process, the staff coordinated actively and worked together with various parties to ensure that the equipment was lifted successfully according to the plan. The technical transformation project for adjusting the raw material structure in order to move nitrogen fertilizer production out of urban areas and into industrial parks, carried out by Shandong Jinmei Mingshui Chemical Group Co., Ltd., is located within the chemical industry park in Di Town, Zhangqiu District, Jinan City, on the existing site of Shandong Jinmei Mingshui Chemical Group Co., Ltd. The total investment in this project amounts to 286,740 million yuan. It involves technological upgrades to the existing ammonia synthesis plants (including one production line with an output of 190,000 tons per year of ammonia alcohol and another line with an output of 250,000 tons per year of ammonia alcohol), as well as the urea production plants (including one production line with an output of 270,000 tons per year of large-grain urea and another line with an output of 400,000 tons per year of urea). The existing 1×130 t/h medium-temperature and medium-pressure circulating fluidized bed boiler will be upgraded to a high-temperature and high-pressure circulating fluidized bed boiler, while the existing 1×75 t/h medium-temperature and medium-pressure circulating fluidized bed boiler will be converted into a 1×180 t/h high-temperature and high-pressure circulating fluidized bed boiler. Upon completion of the project, the boiler setup for the entire plant will consist of 3×130 t/h circulating fluidized bed boilers (2 in operation and 1 as backup) + 1×180 t/h circulating fluidized bed boiler. At the same time, new units for raw water purification, gasification, air separation, shift reaction, methanol washing, liquid nitrogen washing, and sulfur recovery were constructed.
