Gas Separation Membranes are advanced polymer-based separation technologies designed to selectively separate, purify, concentrate, and recover specific gas components from mixed gas streams. Utilizing the solution-diffusion mechanism, membrane systems enable continuous, energy-efficient, and modular gas processing across a wide range of industrial applications.
Our membrane solutions are engineered with modified high-performance polymer materials (typically polyimide-based hollow fiber membranes), delivering reliable separation performance, long service life, and flexible system configurations suitable for petrochemical, energy, environmental, and industrial gas sectors.
Core Technology
Gas separation membranes operate on the principle of selective permeation. Different gas molecules exhibit different solubility and diffusion rates within the membrane material. Under a pressure differential:
- Fast gases (H₂, He, H₂O, CO₂) permeate preferentially through the membrane.
- Slow gases (N₂, CH₄, heavier hydrocarbons) are retained on the high-pressure side.
This allows efficient enrichment, purification, or recovery of target gases without phase change or chemical additives.
Membrane modules are typically constructed with thousands of hollow fiber membranes housed inside pressure vessels, enabling compact, high-surface-area gas processing.
Advantages
- Energy Efficient: No phase change required; lower power consumption compared to cryogenic systems.
- Modular & Scalable: Easy capacity expansion through parallel module integration.
- Compact Design: Skid-mounted, small footprint, easy installation.
- Fast Start-Up: Operational within minutes.
- Low Maintenance: No moving parts inside membrane modules.
- Flexible Operation: Adaptable to flow and purity fluctuations.
Our Gas Separation Membranes
Our gas separation membrane portfolio covers a broad spectrum of industrial gas processing applications, ranging from hydrogen recovery and nitrogen generation to natural gas upgrading and VOCs treatment.
Each membrane solution is engineered based on specific gas composition, pressure conditions, purity requirements, and recovery targets. By leveraging advanced hollow fiber membrane technology and modular system design, we provide reliable, energy-efficient, and scalable solutions tailored to diverse operational environments.
Hydrogen Separation/Purification Membranes
Hydrogen separation membranes are designed to selectively extract and purify hydrogen from mixed gas streams such as syngas, refinery off-gas, and ammonia purge gas. Utilizing materials like palladium alloys, polymers, or ceramic membranes, these systems offer high selectivity and energy-efficient operation. They are widely used in hydrogen production, fuel cell applications, petrochemical processing, and clean energy systems.
Helium Separation / Purification Membranes
Helium separation membranes enable efficient recovery and purification of helium from natural gas and industrial exhaust streams. With high permeability and selectivity, these membranes reduce reliance on cryogenic distillation while lowering operational costs. They are essential in semiconductor manufacturing, medical imaging, aerospace applications, and specialty gas production.
Nitrogen Separation / Purification Membranes
Nitrogen separation membranes typically generate high-purity nitrogen from compressed air through selective oxygen permeation. Based on polymeric hollow fiber technology, these membranes provide compact, on-site nitrogen generation solutions. Applications include food packaging, electronics manufacturing, chemical blanketing, fire prevention systems, and inert gas supply.
Oxygen Separation / Purification Membranes
Oxygen separation membranes selectively enrich oxygen from air by allowing faster oxygen permeation relative to nitrogen. These systems offer continuous, energy-efficient oxygen production without cryogenic processes. They are used in medical oxygen supply, wastewater treatment, metal processing, combustion enhancement, and industrial oxidation applications.
Carbon Dioxide Separation / Purification Membranes
Carbon dioxide membranes are designed for selective CO₂ removal from gas mixtures such as flue gas, natural gas, and biogas. By leveraging advanced polymer or facilitated transport technologies, they provide cost-effective carbon capture and gas upgrading solutions. Key applications include greenhouse gas reduction, enhanced oil recovery, and industrial gas purification.
Natural Gas Separation Membranes
Natural gas membranes are engineered to remove impurities such as CO₂, H₂S, water vapor, and heavy hydrocarbons from raw natural gas streams. These systems improve pipeline quality gas while reducing processing costs compared to traditional methods. They are widely applied in upstream gas processing, offshore platforms, and decentralized gas treatment facilities.
Biogas Separation Membranes
Biogas separation membranes upgrade biogas by removing CO₂, hydrogen sulfide, and moisture to produce high-purity biomethane. Membrane-based upgrading systems are modular, energy-efficient, and suitable for distributed renewable energy projects. Applications include landfill gas recovery, agricultural digesters, wastewater treatment plants, and renewable natural gas production.
Volatile Organic Compounds (VOCs) Recovery Membranes
VOC recovery membranes selectively capture organic vapors from industrial exhaust streams, enabling solvent recovery and emission control. These systems reduce environmental impact while allowing valuable solvent reuse. They are commonly used in chemical processing, painting and coating operations, petrochemical industries, and environmental compliance applications.
