STUDY ON THE EFFECT OF ZIF-8/PEBAX SURFACE COATING ON THE PERFORMANCE OF CTA-BASED HOLLOW FIBER MIXED MATRIX MEMBRANE IN CO2 REMOVAL FROM CH4

Methane is known as the most important element of natural gas since it contributes up to 90% of the overall natural gas composition. This raw natural gas also contains impurities such as carbon dioxide, hydrogen sulphide, water vapour, and nitrogen. As for the carbon dioxide (CO2), it can cause many operational issues include gas hydrate formation, pipeline corrosion, and gas heating value reduction.
