Natural gas dehydration is a cornerstone of safe, reliable, and efficient oil & gas operations. Without it, water vapor in natural gas can cause pipeline blockages, hydrate formation, and equipment corrosion, leading to costly downtime and safety risks.

At Goma, we engineer API 674 reciprocating pumps designed for glycol (TEG/MEG) and methanol injection applications. Built for durability, precision, and long service life, our pumps are trusted across the Middle East, Southeast Asia, and Africa in mission-critical operations where reliability is non-negotiable.

The Role of API 674 Pumps in Gas Dehydration

API 674 reciprocating pumps are the industry benchmark for high-pressure injection. Their constant, accurate flow delivery makes them ideal for gas dehydration and hydrate control.

Key Applications

· Glycol injection (TEG): For moderate moisture removal in contactor towers, ensuring efficient absorption of water vapor.

· Methanol injection: For hydrate prevention in low-temperature or subsea pipelines, where high discharge pressure is essential.
