Recovery of Hydrogen from the Natural Gas Network

The permeation rate of gas species i through a segment of the membrane is calculated by 

Ismail et al.. Carbon-based Membranes for Separation Processes, 

If Henry s law holds for the sorption of ses into the carbon pone network, the permeability of gases in the carbon molecular sieve membranes can be written as 

The hydrogen mole fraction in the pipe line, yuupipe 

The ratio of end-use Itydrogen flow rate to the pipeline hydrogen flow rate,
