Course description

Molecular Sieve Dehydration Fundamentals for Facilities Engineers - FMS - Virtual, Blended Short Course

This short course is from the industry-standard Gas Conditioning and Process course (G-4), known globally as the Campbell Gas Course.

Dehydration is the process of removing water from the gas so that no condensed water will be present in the system downstream of the dehydration unit. Molecular sieve is the only technology that can remove essentially all of the water from the natural gas stream so that the gas can be further processed at cryogenic conditions. Molecular sieve dehydration is required upstream of cryogenic turbo-expander gas plants and in fron of liquefaction (LNG) facilities.

The dehydration unit is critical to the performance of these plants as small amounts of water breakthrough can result in freezing in the downstream heat exchangers, typically Brazed Aluminum Plate Fin exchangers for turbo-expander plants, core and keetle, or possibly coil-wound exchangers for LNG facilities.

Molecular sieve dehydration units are sized and serviced by the molecular sieve vendors. However, facilities engineers need to understand how these dehydrators work and what their key parameters are.

This short course covers the process of molecular sieve dhydration. The online module components cover the following topics:

  • Adsorption dehydration
  • Molecular sieve dehydration performance parameters
  • Molecular sieve regeneration process.

Who should attend?

Production and processing personnel involved with natural gas and associated liquids, to acquaint or reacquaint themselves with gas conditioning and processing unit operations.

This course is for facilities engineers, process engineers, senior operations personnel, field supervisors, and engineers who select, design, install, evaluate, or operate gas processing plants and related facilities.

These short courses are ideal for mid-career professionals that have experience in the industry and have been transferred to a new role or assignment.

They are also ideal for new engineers that need to get up to speed quickly on the primary principles of gas processing with a deep dive on the issues of the short course topics.
