Numerical solution of a mathematical model for hollow-fiber membrane gas separation system
A mathematical model has been developed for the separation of CO2 from natural gas (CH4) using hollow-fiber membrane module. Numerical solution technique using Runge-Kutta-Merson method, available from the NAG FORTRAN Library as the subroutine D02BBF, is used to solved the mathematical model. The mo...

A mathematical model has been developed for the separation of CO2 from natural gas (CH4) using hollow-fiber membrane module. Numerical solution technique using Runge-Kutta-Merson method, available from the NAG FORTRAN Library as the subroutine D02BBF, is used to solved the mathematical model. The model is used to predict the effects of the operating conditions, namely, feed pressure and feed composition on the performance of the separation of CO2 from natural gas (CH4). The solution strategy employs initial value problem estimate and the establishment of feed pressure profile and gas composition profile .
The model developed was used to predict the performance of a commercial size membrane permeator with a diameter and length of 5.08 cm and 304.8 cm respectively.
