Feedstock Supply

The Heze Yuhuang plant is integrated with the Yuhuang Group’s broader refining and gas-processing infrastructure. Confirmed feedstocks include:

Feedstock Source / Notes
Crude benzene / coking benzene External merchant supply and/or Group-affiliated sources; processed in the benzene hydrogenation unit to produce refined benzene
Benzene (refined) Produced on-site via benzene hydrogenation; fed to ethylbenzene production
Ethylene Sourced regionally or from Group-affiliated cracking operations; consumed in ethylbenzene alkylation

Exact feedstock volumes and third-party purchase agreements are not publicly disclosed.

Production Assets, Process Technology & Capacity

The following assets are confirmed at the Heze Yuhuang site:

Unit Capacity (per annum) Process Technology / Equipment Status
Benzene Hydrogenation (苯加氢装置) Not publicly disclosed Hydrogenation of crude/coking benzene to produce refined benzene ✅ Confirmed operational (Sept 2023 site inspection)
Ethylbenzene (EB) Not publicly disclosed Alkylation of benzene with ethylene (catalyst/process licensor not publicly confirmed) ✅ Implied (integrated feedstock to styrene unit)
Styrene Monomer (SM) 200,000 t/a Ethylbenzene dehydrogenation; reactor internals, distributors, and mixers supplied by Ruihua Chemical Co., Ltd. ✅ Confirmed (start-up 2017)
Polystyrene (PS) Not publicly disclosed Polymerization of styrene ✅ In business scope; site-specific production not fully documented


NOT confirmed for this site:

  • Polypropylene (PP) — no evidence of propylene production at Heze Yuhuang

  • Butadiene extraction — included in business scope but no site confirmation

  • MTBE — included in business scope but no site confirmation

  • Ethylene oxide production — sales only, per business scope

Product Portfolio

Confirmed product slate for the Heze Yuhuang site:

Category Products
Aromatics Benzene, toluene, xylene, ethylbenzene, heavy benzene
Polymers Polystyrene
Gases Hydrogen (by-product of dehydrogenation)
Merchant Sales (no storage) Acetone, isopropanol, methanol, ethylene, ethylene oxide, LPG, non-aromatic hydrocarbons, precious metals, water-reducing agents, ethylene glycol, carbon dioxide (food grade)

Development Projects & Recent Updates

  • Styrene Unit (2017): 200,000 t/a ethylbenzene-styrene unit started up; reactor internals supplied by Ruihua Chemical Co., Ltd. — confirmed via Ruihua project reference.

  • Safety & Environmental Inspections: The site was inspected by Luxi New Area officials on September 18, 2023, with a focus on safe production operation of the benzene hydrogenation unit.

Verification & Limitations

Data derived from:

  • Ruihua Chemical Co., Ltd. project reference (styrene unit confirmation)

  • Yuhuang Group corporate news (September 2023 safety inspection)

  • Company registered business scope (NECIPS)

  • Third-party company listing (Huangye88) confirming benzene/aromatics product line

Unverified / Not publicly disclosed:

  • Exact benzene hydrogenation capacity

  • Ethylbenzene unit capacity and process licensor

  • Polystyrene production capacity at Heze site

  • Exact annual feedstock volumes

  • Current production utilization rates

  • Recent ownership/equity changes post-2022

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.
