Gas Desiccation- Natural gas dehydration is accomplished by desiccants in the process of Temperature Swing Adsorption to swing out water vapor, which otherwise would be corrosive and would create hydrates to block flow lines, thus ensuring quality and operability of delivery service. This paper intends to analyse the TSA process available at Basra refinery through temperature and heat exchange plus the dynamics for the mole fraction of water in the system so that performance can be optimized. Results obtained were as follows: 298 K adsorption phase for 8 hours then heating up to 450K in 4 hours with a heat input of 1.25*10-4 MW followed by cooling back down to 298K in 4 hours. The mole fraction for water was kept at .01 during adsorption up until about 100 seconds into heating when it dropped to .00375 then rose back up to .01 over 1000 seconds. This would permit efficient water removal in a 16-hour cycle or approximately 8.3 hours in swift rejuvenation with parallel bed undertakings. Such outcomes offer hope for optimizing TSA frameworks by harmonizing the energy requirements, cycle duration, and dehydration efficacy with the expense of engineering natural gas treatment setups that are affordable and effective while also guaranteeing dependable dehydration and functional soundness.
