Product overview
Triethylene Glycol is the most widely used liquid desiccant for natural-gas dehydration because of its hygroscopicity, high boiling point and low volatility. Gas-treatment buyers should define purity, water, acidity, aldehydes, color and reclamation compatibility rather than purchase on assay alone.
