Applications

Methanol/Glycol Injection

Methanol is mainly used for dehydration & de-icing in the oil & gas industry. Methanol is injected continuously and intermittently. It prevents the formation of hydrates, mainly in offshore sources, and lowers the freezing point of water percentages during oil and gas transport.

Pumps generally in accordance with API 674

Gas, for example, stored in underground caverns, absorbs moisture from the surrounding salt dome and this requires treatment. Glycol is mainly used to reduce the moisture content in gas. Various types of glycol (MEG, TEG, DEG) are used for this purpose, allowing for the compression and further transport of the gas.

A range of pump sizes are available with a range of flow rates and pressure ratings to suit the requirement of any individual well. Hughes Pumps offer bareshaft pumps for system builders or custom designed packages suited for methanol and glycol injection. The pumps are extremely efficient and incorporate a high degree of safety.

Hughes Pumps have extensive experience in supplying pumps for methanol/glycol injection to companies including MODEC, Tullow Ghana, Lewa, Norsk Hydro & Saga Petroleum AS.
