Permeation reduction maps

Similarly to what was done for the coefficients CPC and IC, also for PRC some permeation reduction maps were calculated and developed. These maps are reported and discussed in Section 14.6.4.2. 

In this section, the reduction coefficients introduced before CPC, IC and PRC) are presented in the form of the so-called permeation reduction maps , which... 

All reduction coefficients dealt with in this chapter were calculated from the numerical solution of a complex hydrogen permeation model, opportunely validated by a number of experimental data, and reported in form of permeation reduction maps for several operating conditions. From these maps, the values of CPC, IC and PRC can be read directly and used simply in the modified forms of Sieverts law shown above to evaluate the hydrogen permeating flux, providing in this way a possible novel strategy of membrane module design. 

Finally, in order to observe quantitatively both the influence of concentration polarization and inhibition by CO, the behavior of the overall permeation reduction coeificient is shown in Figure 14.7, which represents a map analogous to the ones presented for CPC and IC.
