St. Fergus Gas Plant

The St. Fergus Gas Plant in St. Fergus, Aberdeenshire, Scotland, is a gas processing plant for the FLAGS pipeline and the Fulmar Gas Pipeline. It is operated by Royal Dutch Shell. The purpose of the plant is to clean the delivered gas and present the Methane content to the adjacent British Gas plant.

The plant has a capacity of around 22.8 Mm scu m/d for the FLAGS line and 2.8 Mm scu m/d for the Fulmar Gas Line. It produces 18.19 Mm scu m/d of gas to the British Gas plant and exports 8,000 tonnes of liquid products to Mossmorran.

Ethane, Propane and heavier products are separated and sent onward to a further plant located at Mossmorran, Fife, Scotland. Separation is by a cryogenic process.

For the Fulmar Gas pipeline, a gas de-sulpherisation plant is used to remove hydrogen sulphide and reduce the water content.
