Natural gas pipelines usually require water content to be 7 lbs/mmcf or less. Typically, glycol (especially tri-ethylene Glycol, TEG) is used to dehydrate natural gas to satisfy this requirement. Dehydration is commonly installed downstream of compression and amine treating, or upstream of gas processing. KMT provides dehydrators for volumes from about 1 MMscfd up to about 400 MMscfd. Out modular skids reduce installation cost and duration.
In a glycol contactor (absorber) column, water vapor is absorbed from the gas under high pressure. In a glycol regeneration skid, conditions of low pressure and high temperature liberate water from the TEG. Finally, the cooled, lean glycol is returned to the TEG absorber, completing the cycle.
Our units can use instrument gas or compressed air and can use electric or pneumatic glycol solution pumps. Our standard skids include burner management systems (BMS) and other environmental/safety devices. We typically build containment into our structural skids, consisting of a solid steel drain pan, sloped to a skid drain connection. KMT can provide treating and dehydration skids with integrated PLC devices to reduce cost while enhancing runtime.
