Gas Dehydration System: Glycol Regeneration (TEG) [Glycol Pump, Reboiler, Contact Tower, BTEX]

Описание: A gas dehydration system is used by oil and gas producers to dehydrate natural gas into a state where it can be sold downstream in the oil and gas production process. In this video, Mark follows the pipes around a gas dehydration system and explains what each piece of equipment is doing to process the gas.

From the gas dehydration system inlet, we look at the three-valve manifold on the contactor tower, as well as the trays, bubble caps and operation of the absorber. Looking at the reboiler skid, we identify the reboiler, surge tank, y-strainer, glycol pump and check valve. We follow the pipes as the rich, wet glycol and dry, lean glycol move through the system of heat exchangers, flash separator, still column and BTEX elimination system.
