New coal gasification project in Inner Mongolia kicks off! Recently, the groundbreaking ceremony for Inner Mongolia Xinlian Aluminum Industry Co., Ltd.’s alumina production project with an annual capacity of 3.5 million tons was held in the New Industrial Park of Tumote Right Banner, Baotou City. As the EPC general contractor for the gas station project, Yu Kuangshi, General Manager of Zhongke Hefei Gasification Technology Co., Ltd. (hereinafter referred to as \"Zhonghe Gasification\"), was invited to attend the ceremony. He joined city leaders from Baotou, officials from Xinhua Metallurgy Group, and representatives from China Huaye to witness the project’s launch. The Inner Mongolia Xinlian Aluminum Gas Station project is Sino-Hydro Gasification’s 13th circulating fluidized bed gasification project in the alumina industry. The project plans to install 3 CGAS circulating fluidized bed gasifiers, each with a gas production capacity of 80,000 Nm³/h. Using local low-rank coal as raw material, these gasifiers will supply clean gas to 2 alumina calcination furnaces with a daily production capacity of 10,000 tons. The gas station will utilize CGAS circulating fluidized bed gasification technology, which features strong adaptability to various feedstocks, low operating costs, and significant environmental benefits; it is an excellent choice for fuel gas in industrial furnaces in industries such as non-ferrous metal smelting, building materials, and glass manufacturing. The CGAS circulating fluidized bed gasification technology has been included in the **Ministry of Industry and Information Technology’s list of recommended energy-saving and carbon-reduction technologies and equipment, as well as in the first batch of advanced and applicable technologies. It has also passed the evaluation by the Environmental Development Center of the Ministry of Ecology and Environment and been approved by the China Petroleum and Chemical Industry Federation; it is therefore a clean production technology recognized by **. The successful holding of this groundbreaking ceremony marks the official commencement of the construction phase for the gas station project at Inner Mongolia Xinlian Aluminum Industry. Zhonghe Gasification will work together with all its partners to deliver high-quality projects, thereby contributing to the improvement of local industries and the sustainable development of the regional economy. At the beginning of May this year, Zhongke Hefei Gasification Technology Co., Ltd. and Inner Mongolia Xinlian Aluminum Industry Co., Ltd. officially signed an EPC turnkey contract for the gasification furnace and its associated auxiliary equipment. The project is located in the New Industrial Park of Tumote Right Banner, Baotou City, Inner Mongolia, and will build a clean gas station to support an alumina production facility with an annual output of 3.5 million tons.

The original poster’s analysis is very accurate; in particular, the mention of gas purification precision and the alignment of overall plant energy efficiency are indeed key issues that affect the long-term operational efficiency of the project. I would also like to add two points that are easily overlooked in practice: first is the control of alkali metal content in coal. Circulating fluidized bed reactors are sensitive to sodium and potassium elements in coal; if their levels are too high, it can lead to slag formation in the gasification furnace or ash accumulation in the heat recovery system. It is recommended that project planners require that the coal quality report indicate the alkali metal levels ； Second is the pressure difference balance logic between the gas station and the roasting furnace, which is crucial for ensuring a stable gas supply under variable load conditions; simulation verification should be carried out as thoroughly as possible during the commissioning phase. Regarding environmental impact assessments, it is recommended to pay attention to the clause on \"baseline oxygen content for converting emission concentrations\" in the approval documents. Inner Mongolia has issued specific guidelines in recent years regarding the baseline oxygen conversion method applicable to gasification furnaces, and this directly affects whether the designed emission outlets meet regulatory requirements.
