Glycol Dehydration Basic Process

The process of removing water from a substance is called dehydration. Gas can be dehydrated by cooling and separating the condensed liquids, by using specially designed low-temperature separation process, by using solid desiccants, or by using a liquid desiccant. Cooling the gas and removing the free water with a separator is the simplest method of dehydration. However, this method is limited by the hydrate formation temperature unless some other hydrate preventive method has been taken. Although there are several methods for removing water from gas, the most commonly used dehydration method utilizes a liquid desiccant known as glycol An Article on Gas Dehydration Process: (Gas Conditioning and Processing) Covering
