High-quality formaldehyde product with low levels of both alcohol and acid was produced. Leveraging its long-term technical expertise, Wuxi Xiyuan Engineering Technology Co., Ltd. developed a unique process for the oxidation of methanol to formaldehyde using the iron-molybdenum method. Based on years of practical application in engineering projects, this company created China’s first such production facility of this kind, as well as the largest operating facility of its kind in the world today. Xiyuan Engineering and International Co., Ltd. maintains a long-term and close partnership with the Swiss company Clariant Chemicals. By utilizing Clariant’s world-renowned FAMAX series of formaldehyde catalysts and EnviCat exhaust gas purification catalysts, along with Xiyuan’s advanced process technologies and extensive engineering expertise, a perfect integration of engineering techniques and catalysts is achieved. This project represents a significant technical breakthrough by Xi Yuan Engineering in the field of formaldehyde, and it is an important milestone in the company’s development. There are many challenges in terms of construction timeline, equipment quality, as well as on-site construction space and safety. From the outset of the project, all the construction workers at Xiyuan Engineering went straight to the site, and with the strong support and cooperation of the project owner, they completed the project handover as well as the subsequent system testing in a timely manner. Clariant Chemical Technology (Shanghai) Co., Ltd. actively cooperated with the progress of the project, providing the FAMAX formaldehyde catalyst in a timely manner in accordance with the project’s timeline requirements. The engineering and technical staff as well as front-line workers at Xiyuan worked together on site, overcame the impact of the pandemic, and completed the loading of the reactor catalysts on time and to high standards, laying a solid foundation for the successful commissioning of the facility. The successful commissioning of this device ensures the prompt operation of the owner’s 1,4-butanediol production facility, keeping pace with the owner’s efforts to optimize the product portfolio and advance industrial upgrading.
