Prevention first, life above all. ----------------------------------------- On November 5th–6th, 2023, the T-301 absorption tower and T-302 regeneration tower for Yiwu Hydrogen Energy Environmental Protection Technology Co., Ltd.’s project on the comprehensive utilization of green energy-powered coke oven gas were successfully installed, marking the completion of the installation of the major equipment for this project. The T-301 absorption tower is 47.01 m long, 4.4 m in diameter, and weighs 315 tons; the T-302 regeneration tower is 66.46 m long, 5.4 m in diameter, and weighs 340 tons. A 1000T crawler crane is used as the main crane, while a 400T crawler crane is used as the auxiliary crane. The comprehensive utilization project of coke oven gas by Yiwu Hydrogen Energy Environmental Protection Technology Company enables the annual production of 90,000 tons of LNG and 160,000 tons of synthetic ammonia from coke oven gas. It is planned to be completed and put into operation by the end of this year. Project nature: New construction. Developer: Yiwu Hydrogen Energy Environmental Protection Technology Co., Ltd. Location of construction: The land designated for the project is within the area reserved by Jiangna Group in the Yiwu Industrial Processing Zone. The project makes use of the infrastructure available there: a transfer agreement has been signed with Jiangna New Materials Co., Ltd. for the use of that land; in addition, gas and syngas are provided by Jiangna New Materials Co., Ltd.’s integrated industrial project for the clean and efficient processing of low-grade coal at a capacity of 5.5 million tons per year, while steam is supplied by the Xin Yi Carbon Energy power generation project. Yiwu Jiangna New Materials Co., Ltd. and the parent company of this project, Xinjiang Xinyi Carbon Energy Environmental Protection Technology Co., Ltd., both belong to the Jiangna Group. The company’s integrated industrial project for the clean, efficient, and comprehensive processing of low-grade coal at a capacity of 5.5 million tons per year was approved by the Autonomous Region’s Department of Ecology and Environment for environmental impact assessment on April 8, 2020 (approval number: Xin Huan Shen 54). Phase 1 of this project has now been completed, including facilities for upgrading coal quality, tar hydrogenation, as well as systems for wastewater treatment and temporary storage of hazardous waste. Total project investment: 2,000 million yuan, of which 27.1 million yuan is allocated to environmental protection measures. Land area: The total land area is 163,742 hm2 (314.4 mu). Construction contents: Construction of a coke oven gas purification plant with an annual capacity of 1.25 billion Nm3, a purge gas purification plant with an annual capacity of 430 million Nm3, an LNG deep cryogenic separation plant with an annual capacity of 90,000 tons, an liquid ammonia synthesis plant with an annual capacity of 160,000 tons, as well as various auxiliary production facilities. Process flow: Utilize the coke oven gas provided by the Jianna 550 project and the methane-enriched off-gas from VPSA to produce LNG, while simultaneously generating ammonia through gas treatment, cryogenic separation, and an ammonia synthesis unit.
