Reduction of energy consumption using toluene solvent in gas dehydration process

In this paper, results of an experimental study on enhancement of TEG regeneration using toluene solvent have been investigated. Effect toluene concentrations ,0.1%wt, for increasing TEG purity in a pilot scale column with 20 sieve tray water concentrations , 10%wt investigated. For study of reflux effect on regeneration performance of TEG, experiment carried out in batch distillation column at two conditions: total reflux and without reflux. By addition of solvent in feed solution, consuming of reboiler duty for boiling of solution decreases to 8.63% for 10%wt water in feed solution.
