WebDistilling the triethylene glycol in the reboiler is easily accomplished because of the extreme differences in the boiling points of water and glycol. Water boils at 212° F while glycol boils at 550° F. However, TEG begins to degrade at 404° F, which is its critical temperature. For this reason, producers heat the wet glycol between 212° F ... WebThis is done by putting the crude oil through a desalter, which is located in the crude unit of an oil refinery.
