Background
Process description
Gas dehydration using glycol
The glycol is separated from the gas and containes moisture with it. The absorbed moisture also contains contaminants, such as H2S, sulfur and solids, that make the water acidic and extremely corrosive.
The low pH value is neutralized by the injection of caustic soda. Afterwards the glycol is heated to about 120° C, vaporizing the water content. The glycol is then ready for recycling and can be injected back into the incoming gas.
In addition to the glycol injection, every large drying system always requires one or more chemical injection systems for neutralization.
There are various processes – from simple injection to so-called high speed columns (GESIP® process) – which ensure fast drying and allow a high gas flow.
