The Logic Behind The Magic." Glycol Dehydration System 8"

TEG Vent Exchanger Outlet Temperature Control


The TEG Vent Exchanger outlet temperature is controlled by TC-FC cascade. The outlet temperature is influenced by Heating medium from TEG Reboiler



The Flow inlet in TEG Vent Exchanger is controlled by FC under normal operation. When outlet temperature of TEG Vent Exchanger is decreases, FV is controlled by TIC for preventing from more decreasing temperature.                                                                  

When outlet temperature of TEG Vent Exchanger is increases, FV is controlled by TIC for preventing from more increasing temperature.
