Wuxi Xiyuan Engineering Technology Co., Ltd. is a Chinese engineering company specializing in process technology for formaldehyde production.
Based in Wuxi, Jiangsu, it focuses on direct oxidation of methanol using fixed-bed catalytic reactors, particularly iron-molybdenum catalyst systems. The company provides process design, complete plant equipment, installation, commissioning, and technical services for large-scale formaldehyde facilities.
It has established a strategic partnership with Clariant since 2017, integrating its process expertise with Clariant’s FAMAX catalysts and EnviCat emission control solutions. Recent projects include 100 kt/a and 120 kt/a iron-molybdenum formaldehyde plants in Inner Mongolia and Hubei province, China, supplying feedstock to downstream pentaerythritol production.
The technology supports high selectivity, reduced pressure drop, improved energy efficiency, and effective VOC removal in chemical manufacturing operations.
**Two world-scale plants (100 & 120 kt/a) started, cutting energy use, boosting productivity and yields, lowering pressure drop by 10-15%, extending catalyst life; VOC off-gas control ≈99% conversion
