Natural gas is dehydrated to avoid corrosion and/or pipeline plugging due to ice or hydrate formation. Glycol dehydration systems remove water from the gas stream by absorption in triethylene glycol (TEG). Normally, the water is then removed from the (rich) glycol by distillation in a glycol regenerator and the regenerated (lean) glycol is recycled back to the absorber tower (contactor).

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
• Minimal glycol loss
• Minimal power consumption
• Optimal plant efficiency and design integrity
• Compliance with QHSE requirements

Standard Features Include:

• Skid mounted design complete with assembly of all equipment, piping and instrumentation for units with gas flows ranging from 1 MMSCFD to 100 MMSCFD.
• Regeneration package with reboiler duty ranging from 250 MBTU/hr. to 3.0 MMBTU/hr.
• Absorber towers with bubble cap trays or packed internals, based on the optimal design and/or Customer requirements.
• BMS and Flame arrestor with both pilot and fuel gas line to minimize gas consumption by increasing burner efficiency.
• Energy exchange pumps to recycle the TEG. Electric pumps are standard for units ≥2 MMBTU/hr.
• Designs are customized for specified operating conditions
• All equipment is manufactured in-house to maintain quality and delivery requirements
• Pressure vessels (towers, exchangers, filters, etc.) are compliant with ASME VIII, Div. 1; National Board registered
• Non-code atmospheric reboiler
• NACE MR 0175 compliant vessels and piping are available
