Let’s give praise and encouragement to the achievements made in China’s chemical technology and equipment sector; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Equipment】A continuously updated summary thread – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Yihua has built the first project in China that converts hydrogen sulfide waste gas generated during coal chemical processes into dimethyl sulfoxide of high added value. Recently, Yihua’s carbon one company’s project for producing 10,000 tons of dimethyl sulfoxide per year successfully produced high-quality products, which were then officially delivered. Currently, the production system is operating smoothly, with all indicators within safe and controllable ranges; the company has taken a solid step forward in the field of sulfur-based fine chemicals. This project utilizes the first set of new processes in China, converting hydrogen sulfide waste gas generated during coal chemical processing into dimethyl sulfoxide products with high added value. This approach significantly enhances the utility of by-products from coal chemical processing, enables the extension and improvement of related industrial chains, and promotes the transformation of the coal chemical industry toward greater sophistication, sustainability, and higher value-added outputs. Faced with new manufacturing processes and complex equipment, and without any prior experience or precedents to follow, the project team pursued technical solutions with a commitment to excellence, conducting repeated process simulations and production trials, which provided a solid foundation for a successful first run and for ensuring that product quality met the required standards. This project is not only a technological breakthrough but also achieves simultaneous development of environmental protection and economic benefits. In the future, the company will take this as an opportunity to continue to focus on the niche area of sulfur chemicals, enhance technical improvements and market development, and continuously strengthen its core competitiveness, thereby contributing more to the high-quality development of the enterprise.
