On December 6, the annual production capacity expansion and recycling renovation project for 6,500 tons of dilute sulfuric acid at Inner Mongolia Yihua was successfully commissioned in one go, producing the first batch of finished concentrated sulfuric acid with a concentration of 96%. Tests have shown that key parameters such as product purity and impurity content fully meet industrial-grade standards. During the renovation process, the project’s technical team overcame numerous challenges related to process and equipment integration, and introduced advanced intelligent control systems that enhanced the safety and stability of the installation, providing a solid foundation for the smooth commissioning of the project and its efficient operation over the long term. The successful commissioning of this project marks a key breakthrough for the company in the recycling of waste acid. Once in operation, this device can significantly reduce waste generation, effectively lowering environmental risks and the pressure associated with waste disposal. It represents an important practice for turning waste into resources and promoting a circular economy. Not only does it improve a company’s efficiency in making comprehensive use of resources, but it also constitutes a concrete step toward implementing green development concepts and facilitating a green, low-carbon transformation. Next, Inner Mongolia Yihua will continue to pursue a development path focused on high-end capabilities, diversification, and circular economy principles. It will keep optimizing its process technologies and energy structure, accelerate technological innovation and industrial upgrading, thereby injecting green momentum into the high-quality development of the enterprise.
