Commissioning

Proper commissioning of glycol dehydration units is essential for safe, reliable, and efficient natural gas processing. This process ensures that the TEG contactor, regenerator, pumps, heat exchangers, and instrumentation are correctly installed, integrated, and validated.

Effective engineering consulting during this phase is crucial to achieve the target water dew point while minimizing glycol losses, foaming, carry-over, and BTEX emissions.

De-bottlenecking

De-bottlenecking glycol dehydration units is essential for oil and gas operators seeking to enhance natural gas processing capacity and efficiency from existing assets increasing throughput of 20 -100% or more, all while incurring far lower capital expenditures and experiencing minimal downtime compared to building new facilities.

Dewpoint

Oil and gas operators encounter significant challenges in cold-climate or high-pressure environments, where the increased water content can lead to freezing, liquid dropout, or operational shutdowns.

This is particularly evident on the North Slope of Alaska, the North Sea, Africa, and the Gulf of America. To address these issues, engineering consulting services often recommend glycol dehydration methods as part of the natural gas processing strategy to enhance operational efficiency.

Foam or Fouling

Fouling and foaming present some of the most persistent and costly challenges in glycol dehydration units within the natural gas processing sector.

These issues directly compromise water removal efficiency, gas quality, and overall plant reliability for oil and gas operators. Contaminants such as entrained liquid hydrocarbons, salts, chlorides, solids (including iron sulfides), and acid gases (H₂S and CO₂) infiltrate the tri-ethylene glycol (TEG) loop.

This triggers foaming that leads to excessive glycol carryover into the sales gas, reduced mass transfer, contactor flooding, low-level trips, and increased chemical consumption. At the same time, fouling from accumulated solids, degradation byproducts, and scales accumulates on contactor trays and packing, heat exchangers, and reboilers.

This buildup restricts glycol circulation, impairs heat transfer, and results in elevated pressure drops, highlighting the need for effective engineering consulting to address these challenges in glycol dehydration.
