Extending the Life of Molecular Sieve Dehydration Switching Valves

Abstract

The molecular sieve dehydration unit is an important process in any plant that uses natural gas as a feed stock. These units are critical in drying natural gas and the processes that follow such as the extraction of natural gas liquids and the production of liquefied natural gas. Switching valves are vital to the proper and efficient operation of these molecular sieve dehydration units. Common issues have been identified that, if understood and addressed in a timely fashion, can help the following: 

  • Avoid start-up problems, both at newly constructed facilities and following major shutdowns. This will allow the units to start up on schedule.
  • Improve the ability of the unit to properly dry the natural gas feedstock, increasing the throughput of the unit.
  • Extend the life of the dryer switching valves, saving money in costly, unscheduled repairs.
  • Reduce unexpected shutdowns. This will keep the revenue stream flowing.
