Our Operations

What We Do 

Operating round the clock, 365 days a year, the Fife Ethylene Plant (FEP) manufactures ethylene by safely converting ethane gas from the North Sea. Ethylene is the base material for the manufacturing of plastics used in food packaging, medical equipment, car parts and many more products in our lives.

ExxonMobil shares the Mossmorran facility with the neighbouring Shell Fife Natural Gas and Liquids plant.

To help explain our process, see our animation below.
