Hydrogen Treatment Technology
Hydrogen-Rich Gas Purification Technology
Hydrogen-rich gas purification technology is a comprehensive industrial solution designed for the deep purification and separation of hydrogen-containing gas mixtures to produce high-purity hydrogen. Centered on Pressure Swing Adsorption (PSA) technology—and integrating high-performance adsorbents, process packages, and specialized program-controlled valves independently developed by Shutai Chemical—this technology effectively removes impurities such as CO, CO₂, CH₄, N₂, and H₂O. It achieves optimized results in both hydrogen purity and recovery rates.
With extensive engineering experience in hydrogen production and gas purification, Shutai Chemical offers end-to-end services—including process design, adsorbent selection, equipment manufacturing, commissioning, and operational optimization—tailored to specific feed gas compositions and product requirements. These services ensure long-term, stable unit operation, with product hydrogen purity meeting various standards, including fuel-cell grade, high-purity, and industrial-grade hydrogen.
Key Application Scenarios
• Hydrogen purification for industrial hydrogen production units (e.g., methanol-to-hydrogen, natural gas-to-hydrogen, and coal gasification-to-hydrogen processes)
• Recovery of hydrogen-containing tail gases (e.g., refinery dry gas, coke oven gas, and ammonia synthesis purge gas)
• Purification of hydrogen by-products (e.g., from chlor-alkali production and propane dehydrogenation tail gas)
• High-quality purification of hydrogen for fuel cells
• Refining of hydrogen for industries such as electronics, metallurgy, glass manufacturing, and chemical hydrogenation
Process Features
• High Hydrogen Purity
Product hydrogen purity reaches 99.9%–99.999% (v/v), meeting the diverse needs of downstream users;
• High Recovery Rate and Low Energy Consumption
Utilizes a multi-bed PSA process combined with intelligent depressurization and purge technologies, increasing hydrogen recovery by 5%–10% compared to conventional processes;
• High Operational Flexibility
Adapts to fluctuations in feed gas flow and composition, with a load adjustment range of 30%–110% and flexible start-stop capabilities. • High Level of Automation
Utilizes sequence control logic to enable unattended operation and remote monitoring, ensuring stable performance and minimal maintenance requirements.
• Thorough Impurity Removal
Uses proprietary adsorbents specifically designed for hydrogen production to deeply remove trace impurities such as CO and CO₂, thereby protecting downstream catalysts and fuel cells.
• Long-term Stability
Features adsorbents with long service lives and low deactivation rates; the unit can operate continuously for 15 years without requiring adsorbent replacement.
