Dehydration with glycol

The rich glycol leaving the absorber must be regenerated to a high purity so that it can be recirculated to the absorber to continue its dehydration function The regeneration is accomplished in the reboiler and the still column above the reboiler The rich glycol is preheated through heat exchange with the regenerated glycol and enters the top
