Recently, the installation of the final section of the methanol washing tower for the shift gas in the first unit of this project, carried out by Sinochem Sixth Construction Company’s Shandong branch, was successfully completed. The methanol washing tower consists of seven sections, with a total weight of 1,121 tons and a total height of 98 meters. The seventh section, which was lifted this time, has a net weight of 60 tons. The project team managed to lift it successfully in one go using a 900-ton crawler crane. The project is located in the Coal, Electricity, Port and Chemicals Industrial Park within the Economic Development Zone of Jiangling County, Jingzhou City, Hubei Province. The total investment for the first phase of this project amounts to 11.528 billion yuan, with commissioning scheduled for 2023. Once completed, it will focus on the clean and efficient utilization of coal, thereby facilitating the extension of the industrial chain into the field of new materials and contributing significantly to the local economic development and social stability. Recently, the synthesis tower shell for the synthetic ammonia unit in the Jingzhou Hualu Hengsheng project, constructed by the Second Branch of 16th Chemical Construction Company, was successfully hoisted into place. The synthesis tower being lifted this time is the core equipment for ammonia synthesis; it has the greatest weight and presents the highest challenges in terms of lifting. Due to limitations at the site, the crane’s route and the lifting location pose serious difficulties for the team. The lifting is carried out primarily using an 800-ton crawler crane, with the assistance of a 400-ton crawler crane for lifting and guiding the equipment, to ensure that it is placed in position in just one lifting operation. The total investment in the Hualu-Hengsheng Jingzhou Modern Coal Chemical Industry Base project is 46 billion yuan. Of this, the first phase involves an investment of 12.3 billion yuan, primarily for the construction of facilities capable of producing one million tons of acetic acid per year, 300,000 tons of organic amines per year, as well as one million tons of functionalized urea per year. The second-phase new energy and new materials project, with a total investment of 5 billion yuan, builds on the foundation of the first-phase project to produce high-end chemical new materials, fine chemicals, and hydrogen-related products. It mainly produces caprolactam, nylon 6, nylon 66, and biodegradable plastics (PBAT, PGA), thereby promoting the development of high-end coal chemical products. The Gas Power Platform project at Hualu Hengsheng’s Jingzhou facility has a total investment of 5.92431 billion yuan; it uses coal as raw material and employs advanced production processes such as the multi-nozzle water-coal slurry pressurized gasification process and low-temperature cryogenic separation process to produce syngas, high-pressure nitrogen, and steam. The total investment in Hualu-Hengsheng’s Jingzhou syngas comprehensive utilization project amounts to 5.60379 billion yuan. The project uses raw syngas from the park’s gas power platform as a raw material to produce downstream products. There are two main product chains: one involves producing ammonia from raw syngas, and then using liquid ammonia and CO2 as raw materials to produce urea ； The second is to produce acetic acid and N,N-dimethylformamide (DMF) using crude syngas as raw material ； Byproduct methylamine, trimethylamine, sulfur, and food-grade CO2 are produced simultaneously.
