Glycol Dehydration

Efficient Natural Gas Dehydration Solutions

When natural gas is extracted from a reservoir, it contains water vapor that must be removed before processing and transportation. The process of removing this moisture, known as gas dehydration, is essential for protecting downstream equipment, preventing corrosion, and ensuring safe and efficient operation.

At SPEC, our Glycol Dehydration Systems are engineered to deliver reliable, continuous performance across demanding environments. Designed in line with international oil and gas standards, these turnkey systems help prevent hydrate formation, maintain gas quality, and extend the lifespan of key process assets.

Process Overview

In a typical TEG (Triethylene Glycol) Dehydration Unit, water-saturated natural gas first passes through an inlet scrubber that removes contaminants before entering the contactor tower. The gas rises through trays or structured packing while lean glycol flows downward, absorbing water vapor. The “rich” glycol exits from the bottom, while the dry gas leaves from the top — ready for further processing or export.

This continuous process ensures dependable water removal, improving gas heating value and minimizing operational risks.
