Abstract
Reports
results of a study of the performance of pressure swing adsorption (PSA),
membrane separation, and gas absorption systems for H2 recovery from refinery
off-gas stream using simulation-based data. The PSA process was simulated using
adsorbents of silica gel and activated carbon for removing heavy and light
hydrocarbons.
Researchers studied the mole fraction profiles of all components and
the relationship between hydrogen purity and recovery as a function of feed
pressure. They employed the
solution-diffusion model to model and simulate a one-stage membrane process.
The gas absorption process with a tower tray was simulated at sub-zero temperature
and the correlation between hydrogen purity and recovery as a function of tower
pressure and temperature was evaluated at different solvent flow rates.
