NATURAL GAS DRYING
Glycol is a hygroscopic liquid, and it is often used to dry Natural Gas simply by passing the gas over its surface in a 'Glycol contactor'. In a continuous process the Glycol is recirculated through a distillation column, which removed the absorbed water. To check that the process is working efficiently the moisture content of the Glycol liquid may be measured immediately after it leaves the distillation column. The installation is exactly the same as for a gas application, except that the liquid flow rate should be kept at about 100ml per minute to avoid abrasion damage to the sensor. The liquid should be at about 20 to 30°C temperature when it reaches the sensor. Usual moisture: <-50°C water vapour dewpoint. |
