Solution Degradation and Contamination

Degraded and contaminated glycol can result in poor water absorption, foaming, corrosion or regeneration problems. Exact levels and speciation of the contaminants can only be done by chemical analysis; however, several on-site observational and simple analytical techniques can help determine the cause and effect of the current contaminant level in the glycol. Dehydration Experts will evaluate the potential side-effects of degraded or contaminated glycol in the system, as well as recommend the appropriate remedial action.

Untreated, the contaminated glycol can result in the following significant issues:

• Off-spec treated gas
• Increased risk of foaming
• Fouled heat exchangers; increased energy usage
• Plugged spray nozzles resulting in hydrate formation/tube damage
• Increased risk of erosion/corrosion of glycol piping
