Inner Mongolia Ordos United Chemical Co., Ltd.’s upgrade project with a total investment of 2.966 billion yuan, aiming to increase synthetic ammonia production to 1.16 million tons per year and urea production to the same level
Thread Content
Project Name: Upgrade Project for 660,000 tons/year of synthetic ammonia and 1.16 million tons/year of urea at Inner Mongolia Ordos United Chemical Co., Ltd.Launch Date: January 5, 2026
Region: Inner Mongolia
Industry/Project Type: Chemicals and Pharmaceuticals/Chemical Raw Materials and Chemical Products/Chemical Raw Materials
Project Owner: Inner Mongolia Ordos United Chemical Co., Ltd.
Total Investment: 2,945.2 million yuan
Current Progress: Project registration completed
Construction Location: Within the United Chemical Plant area in Qipanjing Town, Etoke Banner, Ordos City, Inner Mongolia Autonomous Region
Construction Details: The production process for this project will be changed from using natural gas to produce synthetic ammonia and urea to using coal instead; no additional production capacity or land will be allocated. (1) Phasing out of equipment and upgrades: Phasing out old ammonia synthesis plants using the gas-head process (including outdated equipment such as zinc oxide desulfurization towers, conversion furnaces in stages one and two, high- and low-temperature shift reactors, thermal potassium-alkali carbon removal systems, absorption towers, regeneration towers, and ammonia synthesis towers), as well as related auxiliary equipment such as pumps and heat exchangers. It has been upgraded to a coal-based ammonia synthesis plant, utilizing China’s advanced 6.5MPa space furnace dry coal powder gasification technology. Key process units such as air separation, coal gasification, purification (including carbon monoxide conversion, acid gas removal, and gas refining), ammonia synthesis (including syngas compression, ammonia production, and refrigeration), and sulfur recovery, along with digitalization-related equipment and facilities, are included in this plant. (II) Upgrade and renovation: The existing urea production plants will be upgraded by making use of existing equipment; this includes replacing CO compressors with centrifugal electric-driven compressors, adopting an improved CO stripping process, adding equipment such as dehydrogenation heat exchangers and dehydrogenation preheaters, converting high-pressure ammonia pumps and high-pressure ammonium methanate pumps from steam-driven to electric-driven types, and installing two new medium-pressure ammonium methanate pumps. Progress milestone: January 4, 2026 – Project registration has been approved. (Project registration)
