Shows how molecular sieve dehydration units perform better when designed with full understanding of sieves. Improved design can result in energy savings, fewer plant freezeups, lower methanol usage and less frequent sieve changeouts. Molecular sieves are usually used for gas dehydration ahead of cryogenic plants because they can consistently dry gas to less than 0.1 ppmv. Presents diagram of dehydration configurations. Graphs illustrate the effect of temperature on the equilibrium capacity of molecular sieves, and a comparison of the records of inlet and outlet gas temperatures indicating that the bed heating process is poor. Recommends internal insulation, glycol dehydration, increased cycles, and addition of an extra bed in order to save energy.
