Development of Polyetherimide-Zeolite 4A Mixed Matrix Membrane for CO2/CH4 separation

The monetization of natural gas having high carbon dioxide content (>20mol %) post
technological issues and challenges. Carbon Dioxide (CO2) removal unit should be
installed at offshore to reduce CO2 content before sending to onshore. It has been
found that membrane technology is the best technology for CO2 removal at offshore
due to its simplicity, small size and environmental friendly. However, selection of the
suitable material for membrane fabrication still a big problem and Many previous
research show that Polyetherimide and zeolite 4A have good properties that can be
fabricated a membrane that have high efficiency for CO2 removal.
The main objective of the current study was to develop Polyetherimide-zeolite 4A
mixed matrix membrane. Mixed matrix membrane is the membrane which has
polymer as a based and inorganic material as a filter. The membranes were casted
using solution casting method. The physicochemical properties were evaluated using
FESEM, FTIR, TGA and DSC.
