Hangyang Group and Tianze Group sign contract for gasification upgrade and air separation supply project Author/Source: Gasification World Date: 2023-05-12 Clicks: 114 On May 11, Hangyang Group Co., Ltd. (referred to as “Hangyang Group”) and Shanxi Tianze Coal Chemical Group Co., Ltd. (referred to as “Tianze Group”) successfully signed a contract for the gasification upgrade and air separation supply project. Zhang Pengfei, member of the Party Leadership Group and vice mayor of Jincheng City; Zhang Guorui, Party secretary and chairman of Tianze Group; Li Hu, deputy Party secretary and general manager; Zheng Wei, Party secretary and chairman of Hangyang Group; Yang Qilong and Lü Tingfeng, assistant general managers; along with the main officials from relevant departments, attended the signing ceremony. At the signing ceremony, Zhang Pengfei, on behalf of the Jincheng Municipal Party Committee and the municipal government, extended a warm welcome to the delegation from Hangyang Group. He pointed out that as a coal chemical enterprise under municipal management, Tianze Group is the largest urea producer in the province and the largest producer of large-grain urea in the country, and has long contributed to the development of the coal chemical industry and the economy in Jincheng City. In recent years, Tianze Group has achieved remarkable results in production and operations by focusing on refined management and sound systems. At the same time, Hangyang Group, as a leading enterprise in China’s air separation industry and a pioneer in the gas sector, is China’s largest and oldest manufacturer of air separation equipment, as well as a world-class supplier of such equipment. It serves as a pioneer and leader in China’s gas industry, and constitutes the core force of this industry in the country. Zhang Pengfei emphasized that the successful partnership between these two high-quality enterprises represents a combination of strong entities, as well as complementary strengths. It is hoped that both parties will make full use of their respective characteristics and strengths to carry out in-depth cooperation in areas such as technology, investment, operation, and management, so as to achieve mutual benefit and common progress for the two enterprises. This will help improve the quality and efficiency of the coal chemical industry in Jincheng City, facilitating its transition from traditional coal chemical production to a modern form that features high-end products, sustainability, low carbon emissions, and efficient resource use. It is also hoped that Hangyang Group and Jincheng City will engage in further exchanges and cooperation in broader fields. Zhang Guorui noted that the signing ceremony for the gasification upgrade and transformation project related to air separation supply marked the official commencement of cooperation between Tianze Group and Hangyang Group, and it also signified an important step forward in this gasification upgrade project. As one of the key provincial and municipal projects planned for Jincheng City in 2023, the gasification upgrade project of Tianze Group faces tight deadlines and heavy responsibilities. The signing of an air separation supply contract with Hangyang Group now completes an important part of this upgrade project, laying the foundation for its timely completion. As the leading enterprise in China’s air separation industry, Hangyang Group is the only company in the country that can compete with international air separation equipment; it is a world-class player in this field and a vital asset for the nation, possessing capabilities across the entire air separation industry chain. Through this collaboration to build an air separation unit, both parties can fully leverage Hangyang’s technical and quality advantages as well as operational strengths, while also taking advantage of Tianze’s regional advantages, scale benefits, and efficiency gains. By combining their strengths and complementing each other’s weaknesses, they can achieve a win-win outcome. Tianze Group will cherish and value its cooperation with Hangyang Group, adhering to a strong sense of contractual integrity in order to ensure that the air separation unit is built and put into operation as soon as possible. At the meeting, Zheng Wei and Li Hu signed a gas supply contract for the upgrading and transformation of the air separation unit on behalf of their respective companies. For the gasification upgrade project of Yongfeng Fertilizer Co., Ltd. and the coal gasification plant, which is the subject of this cooperation between the two parties, Hangyang Group will invest in and operate one air separation unit with a capacity of 34,000 cubic meters per hour (oxygen) as well as two air separation units with a capacity of 32,000 cubic meters per hour (oxygen). These units will supply oxygen for the pure-oxygen continuous gasification furnaces in Tianze Group’s gasification upgrade project, and nitrogen for the ammonia synthesis system. Project Overview: In March 2023, the gasification upgrade project of Shanxi Tianze Coal Chemical Group Co., Ltd. (referred to as “Tianze Group”), which had been in preparation for many years and involved a total investment of 2.2 billion yuan, officially commenced construction. The project will replace the existing 100 fixed-bed atmospheric pressure batch gasifiers with 48 pure oxygen continuous gasification units, which can significantly reduce pollutant emissions. Tianze Group has built pure-oxygen continuous gasification furnaces using crushed coal/lump coal from Jincheng, and has fully launched gasification upgrade projects at the coal gasification plant and Yongfeng Company. Neither of these two projects requires the allocation of additional land, the addition of production capacity, or an increase in energy consumption. Instead, continuous low-pressure pure oxygen gas generation furnaces are installed within the existing plant areas, along with air separation units; meanwhile, appropriate modifications are made to the purification and compression sections, as well as upgrades to the boilers. Upon the completion of the gasification upgrade project at Tianze Group: ● The amount of pollutants emitted by the enterprise will be significantly reduced ； ● Major emissions such as particulate matter, sulfur dioxide, and nitrogen oxides are set to be reduced by nearly 50% ； ● Emissions of unorganized pollutants can be reduced by 90% ； ● Zero wastewater discharge is achieved. At present, the preliminary work for Tianze Group’s gasification upgrade project is progressing in an orderly manner. The preliminary preparation work for the project site has entered the demolition phase. Yongfeng Company’s gasification upgrade project is set to be completed and put into operation in April next year ； The gasification upgrade project for the coal gasification plant will be built and put into operation in phases as required. According to the information disclosed in the environmental impact assessment, the coal gasification plant will install 36 new DN3000 pure oxygen continuous gas generation furnaces to replace the existing atmospheric-pressure fixed-bed gas generation furnaces, along with two sets of air separation units with a capacity of 35,000 standard cubic meters per unit time. Shanxi Tianze Gasification Plant uses fixed-bed gas generation to produce synthetic ammonia, urea, and methanol. In 2021, Shanghai Jingye Technology was used to control UGI furnace pollution. Yongfeng Company is constructing 12 DN3600 pure oxygen continuous gasification furnaces to replace the existing 40 fixed-bed batch gasification furnaces. The total investment in Yongfeng Company’s gasification upgrade project is approximately 650 million yuan. Shanxi Tianze Coal Chemical Group Co., Ltd. was formerly known as Jincheng No. 2 Fertilizer Factory, founded in 1978 with an initial production capacity of 3,000 tons of synthetic gas and 12,000 tons of ammonium bicarbonate per year. Through corporate restructuring, mergers and acquisitions, as well as new construction and expansions, it has now developed into a joint-stock enterprise with a comprehensive production capacity of 1.8 million tons of ammonia, 3 million tons of urea, 300,000 tons of methanol, 60,000 tons of formaldehyde, 15,000 tons of melamine, and a waste heat power generation capacity of over 18 MW. Its total assets amount to 4.67 billion yuan, and it employs more than 3,800 people. At present, the company is the largest producer of large-grain urea in the country and the largest urea producer in Shanxi Province.
