In the Flash Vessel the pressure is reduced which enables flashing of dissolved gaseous hydrocarbons including Sulphur gasses and carbon dioxide. To improve the degassing the rich glycol is generally preheated in the Reflux Condensor. The rich glycol remains in the Flash Vessel for a certain period to enable separation of liquid hydrocarbon and glycol based on the difference in gravity between the two media.
- Internals selection and liquid hold-up volume optimized for the application
- May serve as collection vessel between the dehydration sections and glycol regenerators
