Mass concentration of regenerated ethylene glycol
Thread Content
When low-temperature separation is used for natural gas, it is necessary to inject hydrate inhibitors; currently, ethylene glycol is commonly used as such an inhibitor in China. Therefore, an ethylene glycol regeneration unit must be installed in the plant. What is the typical mass concentration of ethylene glycol after regeneration by this unit?
The mass fraction of the ethylene glycol after regeneration in our system is 80%
The liquid coming out of the ethylene glycol regeneration unit, also known as the lean fluid, has a mass concentration of 85%, while the rich fluid emerging from the dehydration adsorption tower has a mass concentration of 75%.
It’s usually around 80%, hehe
The qualified lean solution after regeneration is generally 85%, with a specific gravity of 1.068.
Well, it seems there are requirements in the natural gas dehydration specifications, stating that it should be above 80%. I wonder what the operating parameters of the tower are in actual practice – what about the packing, processing capacity, tower size, and so on?
Are there any manufacturers of ethylene glycol regeneration skids in China?
