Membrane Gas Separation

11.4
Conclusions 
This chapter has provided a range of mathematical models that can be used to characterize 
the effects of minor components on membrane performance. However, the quantity of 
good experimental data that can be used to fi t these models remains quite limited. Good 
characterization of membrane performance in both pre - combustion and post - combustion 
fl ue gases will require accurate experimentally based determination of parameters such 
as Flory 
– 
Huggins interaction parameters, Langmuir constants and plasticization 
potentials. 
Many membrane scientists working in this fi eld focus only on the development of novel 
polymers for these separation processes, as this is of great appeal. Testing is restricted to 
pure gas samples only, or at most, binary mixtures. However, without the full characteri-
zation of each polymer with respect to true mixed gas streams the likelihood of com-
mercial success will remain limited.
