The Facility, Part 7: Gas Dehydration
An export water-dew-point warning leads through the gas-drying train. Explore TEG contactors, lean-glycol purity, regeneration, stripping gas, losses and emissions, then molecular sieves for cryogenic service. Cooling-water assumptions and dew-point measurement connect process fundamentals to an off-spec export stream. Part 7 of 16 in The Facility. Corran Point, its characters, companies and story figures are fictional and illustrative.
