A systematic Design Methodology for Multicomponent Membrane Systems

Abstract Fossil fuel predominantly dominates the world energy supply. With energy demand set to increase, especially for developing countries, CO2 emissions tax and the environmental impact of high CO2 concentration in the atmosphere emphasises the need for a cost effective solution to CO2 emissions capture. Existing CO2 capture technologies are expensive, giving an opportunity for a new technology. Membrane technology is emerging has the alternative solution in the CO2 capture market. Finding the right design and configuration for a membrane system is difficult and time consuming. A simple way has been developed which makes use of a graphical representation of stages of membrane system with cost curve for optimization. This method for systematic membrane design has been tested and seen to be a useful tool in the early design phase of a membrane system. This report develops this methodology in two main areas. First, it extends the graphical methodology from a binary feed to a ternary feed by the development of new design concepts. Secondly, it expands the application of the methodology to more industries other than CO2 post combustion capture by incorporating different process scenarios into the methodology.
