Glycol Regeneration

Regenerates glycol far above 99.5% purity.

Regenerates glycol far above 99.5% purity.

The glycol regenerator or still column includes several sections. The reboiler heats the glycol to approximately 200°C. The glycol regenerator is a packed column mounted on top of the reboiler vessel. Flashed rich glycol is feed in the middle of the packed column. The rich glycol is brought into contact with the hot vapors from the reboiler and is stripped before entering the reboiler vessel. The top of the packing is a reflux section to recover glycol from the vapor. Water vapor leaves the still column at the top. A regenerator condenser may be installed at the top of the glycol regenerator to preheat the rich glycol to enhance flashing and to cool down the water vapor before it leaves the regenerator. Lean glycol leaves the reboiler vessel.

The reboiler can be heated by means of an electrical heater, hot oil/ steam or direct gas fired. In the latter case flash gas, in case suitable, can be used as fuel gas for the reboiler burner. For a more compact design the stripping column might be integrated in the reboiler vessel thus also serving as weir to ensure the heating coils are always submerged in liquid.For the packed columns trays, structured packings or random packings may be used. A random packing generally serves the purpose and is recommended from a sizing and cost point of view.
