Membrane separation-based vapor recovery equipment is primarily used for the recovery and treatment of volatile organic compounds. By leveraging the selective permeability of membrane materials to different gas molecules, the system achieves vapor-gas separation and resource recovery; it is widely employed in sectors such as petroleum storage and transportation, as well as the chemical industry.
It is mainly used to recover vapors generated during storage tank breathing and loading/unloading operations. A membrane separation unit selectively separates the vapor mixture, enriching and recovering hydrocarbon components while allowing the purified tail gas to be discharged in compliance with standards, thereby reducing evaporative losses and environmental emissions.
Membrane separation technology is frequently utilized in secondary vapor recovery systems to treat low-concentration vapors generated during refueling. Characterized by a compact structure and a high degree of automation, it is suitable for space-constrained sites requiring continuous operation, helping to enhance overall vapor recovery efficiency.
It can also be applied to process tail gas treatment and solvent recovery-such as the recovery of evaporated organic solvents and the purification of reaction tail gases. As the membrane separation process does not involve complex phase changes and entails relatively low energy consumption, it is well-suited for industrial environments that demand high energy efficiency and continuous operation.
