Mathematical Modelling of Membrane based Carbon Dioxide Removal from Natural Gas using Spiral Wound Membrane

This Dissertation covers the introduction, literature review, methodology, results, discussions and some recommendations for the project entitled “Mathematical Modelling of Membrane Based Carbon Dioxide Removal from Natural Gas using Spiral Wound Membrane”. Recently, many modelling of membrane is carried out to improvise the current membrane used for separation of carbon dioxide from the raw natural gas but the recent research studies mostly focussed on the development and optimization of Hollow Fibre membrane for sweetening of natural gas instead of the traditional Spiral Wound membrane. Thus, this project aims to develop a mathematical model of Spiral Wound membrane for natural gas treatment with three parameters to analyse: feed temperature, feed pressure, and permeate pressure. Model is developed based in cross-flow model derived by Weller and Steiner for gas separation by using spiral wound membrane through MATLAB. The base operating condition used in for the model is according to literature review from various sources including journals and books. The model proves that feed and permeate pressure has great influence on the membrane performance
