Methanol H₂ Recovery - Petrochemical
Maximize your methanol plant’s output and profitability.
Our advanced membrane systems efficiently recover over 90% of hydrogen from reactor purge gas for recycling, boosting production by 2-4%.
Air Liquide hollow fiber membranes are the most robust solution for highly selective hydrogen purification and recovery in petrochemical operations.
In the methanol reactor purge gas loop, our systems selectively separate the valuable "fast gas" hydrogen from slower gases like methane (CH₄), nitrogen (N₂), and argon (Ar). This highly efficient separation process enables profitable utilization of H₂ and increased methanol production with minimal operational changes.
Key customer benefits
- High-value recovery: Consistently achieve H₂ recovery greater than 90% and H₂ purity greater than 90%.
- Rapid return on investment: Typical systems feature an estimated payback period of less than a year, driven by the significant 2-4% boost in methanol production.
- Simple & compact installation: Skid-mounted systems with high permeability membranes ensure a small footprint, low capital expenditure (CAPEX), and simple installation.
- Reliable operation: Our membrane systems have no moving parts, offering a virtually maintenance-free solution with automated, unrestrained turndown capabilities for enhanced safety and operational ease.

Frequently Asked Questions (FAQ)
How does Air Liquide's membrane system maximize methanol production?
Our advanced membrane technology recovers over 90% of valuable hydrogen from purge gas. Recycling this high-purity hydrogen boosts overall methanol production by 2-4%.
What is the typical Return on Investment (ROI) for the H₂ recovery system?
The significant 2-4% production boost often results in a payback period of less than one year. Our compact, skid-mounted systems also contribute to low capital expenditure (CAPEX).
How reliable is this solution for petrochemical hydrogen separation worldwide?
The membrane systems have no moving parts for virtually maintenance-free, reliable operation. Air Liquide has over 35 years of experience in H₂ separation. We have more than 200 hydrogen purification units operating worldwide.
