Working Principle of SF₆ Gas Separation Membrane
The SF₆ gas separation membrane employs membrane technology to separate and recover SF₆ by leveraging the pressure differential across the membrane. This technology is based on the varying solubility and diffusion rates of different gas molecules in the membrane material. Due to its larger molecular weight and higher boiling point, SF₆ molecules can dissolve and permeate through the membrane material more easily than other gases like nitrogen and oxygen.
The gas mixture entering the membrane system is divided into two streams: permeate and retentate. The permeate stream becomes enriched with SF₆, while the retentate consists of purified other gas components. The core of this process is the membrane’s selective permeability, which facilitates the efficient separation and recovery of SF₆.
Product Features
High Recovery Rate: The SF₆ recovery rate can typically exceed 90%.
High Purity: The concentration of SF₆ after membrane separation can reach 99%, achieving near-complete retention.
Short Payback Period: The initial investment is relatively low, with a typical payback period of 3 to 12 months.
Operational Flexibility: The system can operate flexibly across a load range of 50% to 200%.
Low Operating Costs: The system has no moving parts, with the main energy consumption being the power for compressors.
Compact Footprint: Skid-mounted design for easy installation and maintenance.
Easy Scalability: The system can be easily expanded or upgraded as needed.
Environmentally Friendly: The system is clean and environmentally friendly, with no secondary pollution and the potential for zero emissions.
