Summary Characterization
Heze Yuhuang is best described as an integrated aromatics complex: it converts crude/coking benzene into high-purity benzene via hydrogenation, upgrades benzene to ethylbenzene, dehydrogenates to styrene (200 KTA), and polymerizes to polystyrene. There is no confirmed evidence of propylene, polypropylene, ethylene oxide, or MTBE production at this site.
-
C5 Deep Processing: The Group has expanded C5 utilization (isoprene, DCPD, piperylene) at the Dongming/Heze complex—publicly reported as commissioned in stages between 2018 and 2022.
-
Styrene Expansion: A 500,000 t/a styrene project was completed and brought online across the Yuhuang cluster (Heze site included), using Badger licensed technology.
-
Environmental Upgrades: The plant has undergone multiple rounds of environmental compliance upgrades, including VOC abatement and wastewater treatment improvements, following local government environmental inspections in 2018–2021.
