Instrument Gas Dehydration

Natural gas producers and transporters often use pressurized natural gas as source of pneumatic power for actuating valves and controllers, and for operating instruments.

Impurities in instrument and control gas can lead to significant operational difficulties. Entrained water vapor is a particularly harmful contaminant. Water vapor condenses when saturated gas cools. Wet gas leads to poorly functioning and frozen valves or failed instruments, which can lead to downtime and lost production.
