JT Units & Refrigeration
Wet natural gas forms solids (hydrates) when operated at low temperatures and high pressures (ideal pipeline conditions). As a result it is important to remove water from natural gas.
As you go down this list, the gas dehydration units offer higher water removal (lower dew points), but increase in complexity, capital and operating costs. The correct unit is selected according to final operating conditions and gas compositions, decided by FEED studies.
