Progress on the Technical Upgrading and Renovation Project of the Raw Material Ammonia Plant at Tongliao Jianlong – Author/Source: China Tianchen – Date: 2022-06-08 – Clicks: 28. Recently, the project for the technical upgrading and renovation of the raw material ammonia plant at Tongliao Jianlong, undertaken by Tianchen Company, saw a 90% model review meeting for the gasification, slag-water, and liquid nitrogen washing units, as well as a 60% model review meeting for the shift, low-methane, and CO2 compression units. Relevant parties such as the owner Tongliao Jianlong Acid Production Co., Ltd., the patent holder of the process package, the manufacturers of the complete sets of equipment, and the project team from Tianchen Company attended this meeting. This model review was led by the piping discipline, with support from the process and other disciplines, ensuring the review was carried out in an orderly manner. At the review meeting, relevant personnel from Tianchen Company’s project department gave a systematic and comprehensive explanation by comparing the equipment layout drawings with the 3D model ； All participants conducted a thorough review from aspects such as process requirements, on-site installation, operational inspections, and operation and maintenance. Based on their practical on-site experience, they put forward valuable opinions and suggestions. Through in-depth discussions, an optimization and adjustment plan was ultimately formulated. The experts present unanimously agreed that, at this stage, the content and depth of the model meet the requirements of this model review, while also satisfying criteria related to safety, compliance, integrity, and cost-effectiveness. The successful convening of this meeting signifies the accomplishment of a crucial milestone in the project. It has laid a solid foundation for subsequent operation, maintenance, and repair work, while also creating favorable conditions for the procurement of bulk materials and on-site construction in the future. The site chosen for Tongliao Jianlong Acid Production Co., Ltd.’s project to produce 360,000 tons of synthetic ammonia per year is located in the Mulitu Industrial Park in Tongliao City, Inner Mongolia Autonomous Region. The project involves the construction of a synthetic ammonia production facility with an annual capacity of 360,000 tons; the first phase will have a capacity of 180,000 tons per year, while the second phase will also have a capacity of 180,000 tons per year. The total production capacity of this project is 360,000 tons per year of synthetic ammonia, along with auxiliary facilities such as office areas. The total investment in the project amounts to 2,009,545.1 thousand yuan; the total investment for the first phase, which involves 180,000 tons per year of synthetic ammonia production, is 32,941.2 thousand yuan including taxes. Tongliao Jianlong Acid Production Co., Ltd. was jointly invested in and established by Zibo Jianlong Chemical Co., Ltd., Hebei Meihua Monosodium Glutamate Group Co., Ltd., and Inner Mongolia Tongliang Company. The construction of this project is in line with current **industrial policies and the local master plan. The upgrade and renovation of synthetic ammonia production employs fluidized bed gasification. The powder coal gasification + cyclone separation + washing approach is used to prepare and purify crude syngas. At the same time, saturated steam is produced as a by-product from the medium to high heat energy of the crude syngas. The project includes one 1,500-ton gasifier, with specifications of φ3200×16000. The design pressure is 6.2 MPa, and the operating pressure is 4.3 MPa. The total effective gas volume (CO+H2) is 63,000 m3/h. After the upgrade and renovation, the ammonia synthesis process is as follows: coal gasification, shift conversion, rectisolve, nitrogen wash, and ammonia synthesis at 15 MPa. The project has a production capacity of 240,000 tons/year of synthetic ammonia, 11,000 tons/year of liquid nitrogen, 5,700 tons/year of liquid oxygen, 9,200 tons/year of liquid argon, and 2,290 tons/year of sulfur. Phase out two Ende furnace gasification ammonia synthesis plants.
