Dehydration Unit

Natural gas is dehydrated to avoid corrosion or pipeline plugging due to ice or hydrate formation. The traditional way to dehydrate natural gas is by absorption in triethylene glycol (TEG). Normally, the water is removed from the (rich) glycol by distillation in glycol regeneration tower, and then the regenerated glycol is recycled back to the absorption

Absolute custom designs and builds each system as a complete turn-key package with emphasis given to:

  • Discharge gas moisture content
  • High gas dehydration capacity
  • Minimum glycol losses
  • Minimum power consumption
  • Optimum plant efficiency and design integrity
  • Compliance with SHEQ requirements

Standard Features

  • Absolute design, engineer and manufacture skid mounted units with gas flow ranging from 1 MMSCFD to 100 MMSCFD.
  • Regeneration package with reboiler duty ranging from 250 MBTU/hr to 3.0 MMBtu/hr.
  • We manufacture Absorber tower either with bubble cap trays or structured packing internals, based on the optimum design requirements.
  • Regeneration package will be built in single skid complete with assemble of all equipment, piping and instrumentation.
  • BMS and Flame arrestor with both pilot and main gas line to minimize the fuel gas consumption by increasing the burner efficiency.
  • Energy exchange pumps will be used to recycle the TEG for units up to 2 MMBtu/hr and electric pumps for the unit 2 MMbtu/hr and larger units.
  • Absolute also manufacture custom glycol dehydration units for different gas operating conditions and flow rates.
  • We manufacture all the equipment in our fabrication facility, which allows us to maintain high level of quality and deliver units with expedited lead times to meet the customer tight schedules.
