The natural gas dehydration process

The natural gas dehydration process. Natural gas from wells invariably contains humidity. Gas also becomes wet in the sweetening unit of a gas processing facility when it comes into contact with the aqueous solution of a solvent, such as methyl diethanolamine (MDEA), used to remove the acid gases contained in the raw gas.
