Recently, the approval was granted for the change registration of the caprolactam and new materials integrated production project at Inner Mongolia Jihui Shun New Materials Co., Ltd. Construction location: Ordos City -- Jungeer Banner -- Dalu Industrial Park in Jungeer Economic Development Zone. Total investment: 1,321,378 million yuan, of which self-funded amount is 1,321,378 million yuan; bank loans applied for: 0 million yuan; other sources: 0 million yuan. Planned construction period: from 2024/04 to 2027/10. Construction scale and scope: production of 450,000 tons per year of caprolactam, and 640,000 tons per year of ammonium sulfate (by-product). The main production facilities include: 1 set of coal-to-hydrogen plant along with the associated air separation unit, 1 set of synthetic ammonia plant with an annual capacity of 300,000 tons (the synthetic ammonia produced is used entirely internally as an intermediate product), 1 set of sulfuric acid plant with an annual capacity of 500,000 tons, 1 set of hydrogen peroxide (27.5%) plant with an annual capacity of 600,000 tons, 1 set of ** plant with an annual capacity of 400,000 tons, 1 set of caprolactam plant with an annual capacity of 450,000 tons, as well as various utility facilities. Inner Mongolia Jihui Shun New Materials Co., Ltd. plans to build an integrated project for caprolactam and new materials at the Dalu Coal Chemical Industry Base in Zhungeer Banner, Ordos City. In December 2024, the Ordos Municipal Ecology and Environment Bureau published a notice regarding the acceptance of the project’s environmental impact assessment report. Project Overview: Project Name: Integrated Production Project of Caprolactam and New Materials by Inner Mongolia Jihui Shun New Materials Co., Ltd. Developer: Inner Mongolia Jihui Shun New Materials Co., Ltd. Project Type: New chemical manufacturing project. Location: Dalu Coal Chemical Industry Base, Zhungeer Banner, Ordos City, Inner Mongolia; coordinates of the project site: 111°12’57.35” east longitude, 40°1’16.26” north latitude" ； To the east of the project is Jingsan Road, to the south there is reserved land for industrial parks, to the west it is adjacent to Xihuan Road, and to the north it is next to Weiqi Road. Project area: The site of this project has a maximum width of approximately 914 meters in the north-south direction and a maximum length of approximately 1653 meters in the east-west direction, with a total area of around 150 hectares (1,500,000 m²). Construction scale: The main production capacities and facilities of the project include an ammonia synthesis plant with an annual output of 300,000 tons, a sulfuric acid plant with an annual output of 500,000 tons, a hydrogen peroxide plant with an annual output of 600,000 tons, a cyclohexanone plant with an annual output of 400,000 tons, a caprolactam plant with an annual output of 450,000 tons, along with supporting auxiliary facilities. Total project investment: The total investment amounts to 1,321,378 million yuan, all of which is funded through own capital; no bank loans were sought. Of this, the construction investment amounts to 1,007,970.92 million yuan, the interest during the construction period is 41,406.48 million yuan, and the working capital required at the start of operations is 13,299.31 million yuan. Main process technologies of the production plant: Air separation: Oxygen internal compression and deep cryogenic air distillation processes are employed. The air separation unit is designed to produce 40,000 m3/h of oxygen; under normal conditions, it produces 35,445 m3/h of oxygen. Coal gasification: Water-coal slurry + semi-waste boiler gasifier is used. Two gasification furnaces are installed (1 in use and 1 as backup), with a coal feeding rate of 1545.6 t/d. The output of useful gas (CO+H2) is 100,000 m3/h, while the normal gas production rate is 96,025 m3/h. Purification: The conversion is carried out using a sulfur-resistant conversion process, along with a partial conversion process with a low water vapor ratio; it is a technology that combines one stage of adiabatic conversion with one stage of isothermal conversion. Desulfurization and decarbonization are achieved through low-temperature methanol washing. The gas is purified by liquid nitrogen washing. PSA hydrogen production: The main task in the hydrogen production process is to separate hydrogen from the purified gas obtained from low-temperature methanol washing, using a single-stage process. Hydrogen production rate: 29296 m3/h. Synthetic ammonia: Ammonia synthesis at low pressure (15 MPa). The designed annual output of synthetic ammonia was 300,000 tons, while the actual annual output was 244,998 tons. Sulfuric acid: rapid sulfur melting, liquid sulfur filtration and purification, mechanical atomization for sulfur combustion. The air blower is located upstream of the drying tower, using 98% acid to dry the air. Four stages (3+1) with two conversions, nicotinic acid absorption followed by two stages of 98% acid absorption. The scale is 500,000 tons. Hydrogen peroxide: Hydrogenation process using anthraquinone-process fixed-bed palladium catalysts. 600,000 tons of hydrogen peroxide. **: The benzene fraction is partially hydrogenated to produce cyclohexene; cyclohexene is hydrated to produce cyclohexanol; cyclohexanol is dehydrogenated to produce **. The production capacity is 400,000 tons. Caprolactam: The **hydroxylamine method** using benzene as a raw material is employed. The designed annual production capacity is 450,000 tons.
