VOCs Recovery Membrane – Organic-Selective for Gas Purification

This VOCs Recovery Membrane utilizes an organic-perm selective separation layer that enables faster dissolution and diffusion of organic components through the membrane, effectively separating VOCs from carrier gas streams. The membrane features a three-layer structure comprising a raw material side, support layer, and separation layer, with the permeation side collecting enriched organic compounds. Key performance advantages include five times concentration and ten times purification capability. The membrane exhibits high bonding strength with an expected service life of 5 to 8 years. The system incorporates the world‘s first conductive diversion network technology, achieving intrinsically safe explosion-proof certification for enhanced operational safety in hazardous environments. Substrate, functional layer, and sealant modifications provide superior swelling resistance against organic solvents.

The membrane process is typically deployed within a gradient coupling process that integrates absorption, condensation, membrane separation, and adsorption stages. This configuration achieves over 95% solvent recovery rates while maintaining power consumption at approximately 70% of conventional absorption-adsorption processes. Demonstration projects have successfully treated dichloromethane tail gas and mixed aromatics in petrochemical storage at capacities of 1000 Nm³/h and 300 Nm³/h respectively, achieving NMHC levels below 120 mg/m³ and benzene below 4 mg/m³.

This product belongs to our VOCs Recovery Membrane portfolio, which complements our broader Inorganic Membranes and Silicon Carbide Ceramic Membranes for high-temperature gas-solid applications. Unlike Ceramic Membrane Gas-Solid Separation Equipment designed for particulate removal from hot flue gases, this membrane targets organics recovery. It also serves as a downstream polishing step following Liquid Filtration & Purification in chemical processes. Typical applications include oil and gas recovery in storage, transportation, and refining; VOCs recycling in chemical and pharmaceutical plants; and recovery of organic monomers and light hydrocarbons.
