Special acid-resistant molecular sieves can maintain their dehydration capabilities over long periods of onstream use without undesirable side effects. With the increasing value of natural gas, many previously uneconomical acid gas fields are now considered for processing by acid-resistant molecular sieves. Molecular sieves are attractive for gas drying since no precooling is required as with glycol dehydrators. Commercially proven molecular sieve technology produces product gas steams containing less than 0.1 ppmv water. Applicable pressure ranges are from subatmospheric to more than 100 atm and temperature ranges from below zero to 200C. Design technology includes mass transfer rate information as a function of temperature, pressure, mass flowrate, viscosity, water content and carrier composition. The paper discusses the composition of sour gas, natural gas drying, molecular sieve properties, the drying process, commercial dryers and dryer performance, regeneration procedures, and COS formation in commercial dehydrators.
