Abstract:

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.
