Optimal design and operation of molecular sieves for gas dehydration—Part 2

Part 1 of this article examined the main design elements of a molecular sieve dehydration unit, although it is virtually impossible to design such a process unit without taking operational aspects into account. However, once a molecular sieve unit is constructed and the gas processing plant has started up, some elements during its operation require special attention. Part 2 focuses on the operation of a molecular sieve unit used for natural gas dehydration. Debottlenecking and troubleshooting options are also discussed. Addressing common issues. A contributing factor to molecular sieve deactivation is the deposition of liquids, such as amines, that originate from the upstream amine unit be
