Molecular Sieve Dehydrators

Molecular sieve dehydrators are typically used in the natural gas industry to achieve a very low water dewpoint of -150°F or less or 0.02 ppmv prior to cryogenic processes located downstream.

ALCO designs custom units to meet a variety of operating conditions and as an example can incorporate the following depending on the Customer’s needs:

  • High efficiency inlet filter coalescers to ensure long, trouble free bed life.
  • 2, 3 or 4 tower units in a closed loop or open loop configuration depending on dewpoint required.
  • High efficiency dry gas dust filters to protect downstream equipment from desiccant fines.
  • Regeneration gas heaters using either a direct fired salt bath heater, heat medium heater or an electric immersion heater.
  • Regeneration gas heat exchangers to conserve regeneration gas heater duty.

Modular construction:
Molecular sieve dehydrators can be packaged to your requirements including:

  • Your instrumentation and valving requirements.
  • Individual Customer General Specifications.
  • Sales gas metering.
  • Single skid construction or multiple skids depending on your transportation limitations.
  • Building either installed at our facility or field erected.
  • Electrical work shop installed at ALCO.
  • Preparation for transit to international locations on either ’break bulk’ or ‘containerized’ (sizes permitting) basis.
