The company operates integrated production facilities focused on formaldehyde and its derivatives, including pentaerythritol. It maintains pentaerythritol capacity of approximately 70 kt/a, supported by dedicated formaldehyde plants with capacities of 100 kt/a in Inner Mongolia (started March 2026) and 120 kt/a in Hubei (commissioned November 2025).
The group employs iron-molybdenum catalysts in its formaldehyde units and has implemented emissions-control technologies for VOC abatement. Its operations emphasize process integration between upstream feedstock production and downstream specialty chemical manufacturing.
Also known as 湖北宜化集团.
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
