With the development of clean fuel technology, China's methanol industry has experienced rapid growth, and various new methanol catalysts have emerged and been applied in industrial production, achieving significant economic benefits. However, during use, due to various factors, the service life of methanol catalysts is far from meeting the design requirements. Among them, except for sulfur and chlorine, which can easily cause poisoning and deactivation of methanol catalysts; Carbonyl metals, arsenic, and trace amounts of ammonia are also important causes of poisoning and deactivation of methanol catalysts, affecting their service life. Therefore, solving the purification of methanol synthesis feed gas is crucial for extending the service life of methanol catalysts. At present, the main gap between domestic small and medium-sized nitrogen fertilizer enterprises and foreign methanol enterprises is also in the level of synthesis gas purification. Although the promotion and application of precision desulfurization and dechlorination technologies have played a significant role in extending the service life of methanol catalysts in recent years, further improving the purification level of synthesis gas is still an urgent task.
After years of research on the formula, process, and carbonyl metal detection methods of decarbonylation metal purifiers, our company has successfully developed the ET-8 decarbonylation metal purifier, which can remove trace impurities such as carbonyl metals in synthesis gas to below 0.1ppm. It has the characteristics of wide operating temperature range, large capacity, and convenient and flexible use, which can effectively protect methanol catalysts, significantly extend their service life, reduce equipment operating costs, and improve the economic benefits of enterprises.
