Xinjiang Yingtai Energy’s sulfur-based acid production project came online
Thread Content
According to Sinochem New Network, on March 28, Xinjiang Yingtai Energy Technology Co., Ltd. (hereinafter referred to as Yingtai Energy) began operating its 300,000 tons per year sulfur-based sulfuric acid production facility. This facility will help fill the gap in sulfuric acid production capacity in the region, providing a stable supply of raw materials for industries such as fertilizer manufacturing, lithium batteries, and new materials. The total investment in this project is 150 million yuan; it will have an annual production capacity of 250,000 tons of industrial sulfuric acid at 98% or 93% purity, as well as 50,000 tons of fuming sulfuric acid at 105% purity. Additionally, it will be capable of producing 360,000 tons of medium- and high-pressure clean steam per year. The project utilizes the globally standard \"two conversions and two absorptions\" sulfur-based sulfuric acid production technology. Compared with traditional processes such as the roasting of pyrite and the production of sulfuric acid from flue gases from non-ferrous metal smelting, this technology offers significant advantages in terms of environmental friendliness, lower energy consumption, and higher efficiency. It not only reduces pollutant emissions significantly but also results in sulfuric acid of higher purity with extremely low levels of impurities, meeting top-quality standards. Mian Zuoxiang, deputy general manager of Yingtai Energy, said that once the project is put into operation, the annual output value is expected to exceed 300 million yuan. In addition to ensuring a steady supply of sulfuric acid, the project will also promote the coordinated development of related industries such as hazardous chemicals storage and trading, as well as bulk commodity logistics. This will further improve the local upstream and downstream industrial chain structure and contribute to the optimization and upgrading of the regional industrial structure.
Judging from the project description, Yingtai Energy’s sulfur-based acid production project indeed holds great industrial value. As a colleague in the chemical industry, I would like to add a few observations from a technical perspective: The \"two conversion and two absorption\" process is indeed more environmentally friendly than traditional contact methods. However, it is important to pay attention to the details of the exhaust gas treatment system, as this plays a key role in ensuring that emission standards are met consistently over time. It is worth noting that the project includes a steam production capacity of 360,000 tons; this cogeneration design is particularly useful in Xinjiang, as it not only meets the heat requirements of the sulfuric acid production process but also generates revenue by supplying heat to surrounding industrial parks. For a newly built facility, it would be helpful to learn more about the catalyst selection (vanadium-based or new types of catalysts) as well as the design features of the converters, as this information can be very useful for colleagues in the industry. I look forward to the project owners releasing more operational data in the future, especially regarding energy consumption and emission levels.
