On-site oxygen generation, off-gas purification, and steel-chemical co-production — from engineering design to lifetime O&M support. Trusted by 70+ steel enterprises across 20+ countries.
400+ large-scale gas separation systems delivered · 18+ years of proven performance
A comprehensive gas separation product portfolio — from oxygen-enriched ironmaking to off-gas chemical valorization.
VPSA-O₂ for Blast Furnace Enrichment
Large-capacity oxygen generation up to 100,000+ Nm³/h at 80–93% purity. Increases molten iron output by 10–20% while reducing coke consumption and per-ton iron costs.
VPSA/PSA-O₂ for EAF Steelmaking
Economical oxygen supply (3,000–15,000 Nm³/h) that accelerates melting, improves decarburization, and boosts EAF productivity — eliminating dependence on expensive liquid oxygen.
PSA-CO Purification from Off-Gas
Proprietary PSA-CO technology purifies carbon monoxide from BFG and BOFG to 99%+ purity, enabling direct use as feedstock for formic acid, ethylene glycol, and acetic acid production.
PSA-H₂ Purification
Hydrogen recovery and purification from coke oven gas and other mill off-gases, supporting chemical processes, DRI operations, and emerging hydrogen-based steelmaking pathways.
Steel-Chemical Co-Production
End-to-end engineering solutions combining CO/H₂ purification with downstream chemical processing — transforming low-value exhaust gases into high-value chemical products.
High-Efficiency Adsorbents (PU-8 & PU-1)
Proprietary lithium-based molecular sieve PU-8 for oxygen generation and CO-selective PU-1 — both internationally patented, delivering superior separation performance and longevity.
Every steel mill's pain points are unique. Here's how PKU Pioneer delivers measurable results where they matter most.
Eliminate Liquid Oxygen Dependence and Volatile Pricing
Many steel mills still rely on purchased liquid oxygen at prices that can double during periods of tight supply, directly eroding profit margins. PKU Pioneer's on-site VPSA-O₂ plants produce oxygen at a comprehensive cost below ¥0.3/Nm³ — a fraction of liquid oxygen pricing.
One recent project supplied 12,500 Nm³/h of enriched oxygen to two blast furnaces, eliminating the client's reliance on liquid oxygen that had surged from $57 to over $114 per ton.
Typical payback period: under 2–3 yearsCut Energy Consumption by 30%+ vs. Cryogenic Air Separation
Traditional cryogenic ASUs are energy-intensive and expensive to operate, especially for mills that don't require ultra-high-purity oxygen. VPSA technology delivers oxygen at 80–93% purity with energy consumption as low as 0.29–0.32 kWh/Nm³.
This makes VPSA the ideal complement to existing ASU infrastructure — handling enrichment-grade oxygen at a fraction of the operating cost while ASUs continue to supply high-purity streams where needed.
30%+ energy savings over cryogenic ASUTransform Waste Gas into Billions in New Revenue
Blast furnace gas, converter gas, and coke oven gas contain valuable CO and H₂ that are typically burned for low-grade heat. PKU Pioneer's PSA-CO technology, powered by the patented PU-1 adsorbent, purifies CO to 99%+ purity for chemical synthesis.
Research published in Nature Chemical Engineering confirms that steel-chemical co-production can reduce greenhouse gas emissions by 7–22% depending on carbon pricing scenarios — one of the most practical near-term decarbonization strategies for steelmakers.

Real projects, real results — from East China to South Asia, delivering measurable cost savings and emission reductions.
Blast Furnace Oxygen Enrichment for a Leading Steel Group
Facing a 10,000 Nm³/h oxygen shortage across two blast furnaces (1,080 m³ and 1,250 m³) with liquid oxygen prices doubling to $114/ton, the client turned to PKU Pioneer. A 12,500 Nm³/h VPSA-O₂ system was designed, installed, and commissioned in just 73 days — a construction speed record.
Multi-Phase VPSA Oxygen Program for a Top-Tier Steelmaker
One of India's largest steel producers partnered with PKU Pioneer across four project phases (2018–2020), building VPSA plants with a combined capacity of 36,000 Nm³/h (~1,200 TPD). All plants achieved standard production targets and now serve multiple blast furnaces.
Steel-Chemical Co-Production: Converter Gas to Formic Acid
A specialty steel company converted converter gas into high-value chemicals. PKU Pioneer's PSA-CO technology purified 18,200 Nm³/h of CO at 98.5% purity, feeding two 100,000-ton formic acid lines and a 50,000-ton oxalic acid line — cutting capital investment from ¥3.3B to ¥1.8B.
Trusted by steel enterprises of every scale — from integrated mills to specialty producers.
The VPSA oxygen system delivered by PKU Pioneer met all performance targets on the first commissioning attempt. The energy savings compared to our previous liquid oxygen procurement have been substantial, and the after-sales support has been outstanding.
We selected PKU Pioneer after evaluating multiple international suppliers. Their combination of proprietary adsorbent technology, competitive pricing, and willingness to provide comprehensive on-site support in India made them the clear choice. We have since expanded to four project phases.
The retrofit of our aging PSA oxygen units exceeded our expectations. PKU Pioneer's team identified root causes that the original supplier could not solve, and the upgraded units now perform better than their original design specifications.
