Construction of the gas purification unit for Inner Mongolia’s 2.6 million tons per year coking project has begun. Author/Source: Coal Chemicals Journal. Date: July 26, 2021. Clicks: 21. A few days ago, the construction of the gas purification unit for the second phase of Inner Mongolia Hengkun’s coking project officially started. The safety supervisor of the Inner Mongolia Hengkun Project, the director of Taiyuan University of Technology Supervision Company, the project manager from MCC Coking & Refractories Research Institute as the general contractor, and the person in charge of the Tianjin branch of The 13th Chemical Construction Company attended the groundbreaking ceremony. The project plans to construct 2 coke ovens with 65 chambers each, measuring 5.5 m in diameter and operating on the single-heating principle. It will include facilities for wet quenching of coke, with options for dry quenching as well, along with coal preparation, coke screening, gas purification, production auxiliary facilities, and administrative and living facilities. The implementation of the project will fully leverage the region’s resource advantages, extend, supplement, and strengthen the coal industry chain, and facilitate the development of Ordos City’s coking industry into a large-scale, intensive, and highly efficient sector. The annual production capacity of 2.6 million tons of rammed coke and related comprehensive utilization project of Inner Mongolia Hengkun Chemical Co., Ltd. is located in the Shanghai Miao Fine Chemicals Park in Ordos City, Inner Mongolia Autonomous Region. The project was awarded to MCC Coking & Refractory as the EPC contractor; it involves the construction of 2 rammed coke ovens with 65 chambers each and a diameter of 5.5 meters, along with wet quenching systems for coke, options for dry quenching, as well as facilities for coal preparation, coke screening, gas purification, production support services, and administrative and living areas. The project entails the planned construction of a coking multi-product complex with an annual capacity of 2.6 million tons. Phase I involves a 1.3-million-ton-per-year stamp-charging coking plant coupled with a project to produce 120 million m³/year of liquefied natural gas from coke oven gas. With a total investment of 1.5 billion yuan, the project was completed and put into operation in 2011. Its main products include coke, coal tar, crude benzene, ammonium sulfate, and liquefied natural gas. The project to produce liquefied natural gas from 120 million m3/year of coke oven gas adopted the world-leading technology from the British company Davy, becoming the world’s first project of its kind. In 2019, a total of 967,100 tons of coke, 58,400 tons of tar, 15,800 tons of crude benzene, 10,800 tons of ammonium sulfate, and 25,100 tons of LNG were produced ； Over the whole year, sales revenue amounted to 1.226 billion yuan, with profits reaching 186 million yuan. The budgeted investment for the second phase of the project, which involves 1.3 million tons per year of compacted coke production along with 200,000 tons per year of methanol production, was 2.24 billion yuan. Construction began in 2013; it was suspended in 2015. In 2019, the procedures for technical upgrades, environmental impact assessments, and resumption of construction were completed, and work resumed. Upon the completion of Phase 2, Hengkun Chemical Company will be able to produce 2.6 million tons of coke per year, generating an output value of 3.5 billion yuan and tax revenues of around 400 million yuan; it will thus become a major chemical enterprise in the Shanghaimiao area.
