Pressure swing adsorption is one of the most common and reasonable methods of
Nitrogen gas production and has been investigated and studied by many researchers
during the last few decades. Due to the cost of conducting laboratory activities and
the limitation of changes in the effective parameters, the modeling of this process
has been considered. With the progress and growth of simulation for estimating
results such as artificial neural network, the attention of some researchers has been
drawn to the application of these methods in the adsorption process and brief
researches have been made in the field of predicting the behavior of Pressure Swing
Adsorption with artificial neural network.
The simulation of Pressure swing adsorption in four steps (pressurization,
adsorption, Purge and Blow down) was carried out for the purpose of nitrogen gas
separation using CMS adsorbent. The effect of CMS adsorbent performance on
various variables in steady state conditions was simulated.
This simulation was predicted at temperatures (293.15, 298.15 and 303.15) Kelvin
and pressures (5, 6, 7) bar using the Langmuir Freundlich isotherm. Finally, the
results obtaint from the Aspen adsorption software is predicted by ANN method for
PSA adsorption system.
The prediction results of the ANN model were agreement with the results of Aspen
adsorption software. The coefficient of determination or error value (R) is close to
unity.
By analyzing the presented results, it was observed that the use of CMS adsorbent
and Langmuir-Freundlich isotherm for nitrogen separation were well performed
shown a good agreement.
