The purpose of this report is to study on `The Removal of Water Vapour from. Natural
Gas by Using Membrane Separation'. This report includes the objectives, scopes of study,
problem statement, literature review, methodology, results, discussion, conclusion and
The main objective of this project is to analyze the performance and efficiency of
membrane to remove water vapour from natural gas. Literature review is studied to obtain the
properties and characteristics of flat membrane. Experimental lab is conducted to test the
performance of the membrane under various operating pressure. The percentage of water vapour removal from methane and hydrocarbon loss under
various pressures is plot. It is observed that the removal of water vapour increases as pressure
increases, which means the membrane separate more water vapour from methane at high
pressure. Unfortunately, the percentage of hydrocarbon loss also increases as the pressure
increases. Thus, it is recommended for next study that optimization is to be conducted based
on cost analysis in order to minimize hydrocarbon loss and maximize water vapour removal
by the membrane.
As the conclusion, the objective of this protect to analyze the perfonnnce of the
membrane is achieved. The flat membrane used in this project is classified as asymmetry,
integrally skinned and dense top layer membrane. The membrane consists of mainly O-H, NH,
C=O and C- H functional groups. The degradation temperature of the membrane is
430.60°C. As for performance analysis, it is obtained that the percent of water vapour removal
and hydrocarbon loss increase as the pressure increases
