Mossmorran & Braefoot Bay complexes
The Shell UK Limited (Shell) Fife Natural Gas Liquids Plant (FNGL) receives natural gas liquids (NGL) from the St. Fergus gas terminal, separating the incoming natural gas liquid stream into propane, ethane, butane and natural gasoline.
Ethane is sent to the adjoining ExxonMobil Chemical Limited (ExxonMobil) Fife Ethylene Plant (FEP) whilst the other products are sent off-site to the adjacent Avanti gas terminal, via road tanker or via pipeline to the Braefoot Bay Marine terminal for export by ship.
The ExxonMobil FEP produces ethylene from ethane through a process known as “thermal or steam cracking”. Additional ethane can be received from Ineos Chemical Grangemouth Limited via a pipeline.
Ethylene is either exported by ship via the Braefoot Bay Marine Terminal or to other consumers in the UK via the cross-country ethylene distribution system.
Latest update
Air quality and noise in community locations
Date published: 14th August 2023
We continue to monitor air quality and noise in community locations.
What we have done
Communities around the Mossmorran Complex are now able to see the air quality in their area in close to real time, with the launch of a new monitoring network from SEPA.
It follows on from community participation in the design of a new air quality monitoring network, and a refreshed online regulatory hub designed to make it easier than ever to find information about SEPA’s regulation of the Fife Natural Liquids Plant and Fife Ethylene Plant.
