Scottish ethylene plant cuts emissions

Emissions and fuel gas consumption will be cut dramatically at ExxonMobil’s Fife Ethylene Plant in Scotland, following the completion of a two-year project to link one more furnace at the site to gas turbine that drives the plant’s main compressor. Until recently, only six of the seven furnaces have been heated with the help of exhaust gases from the turbine.

Using exhaust gases provides multiple benefits. It enables the recovery of heat from the gas turbine exhaust gases that might otherwise be lost, it cuts emissions and it reduces the amount of fuel gas the plant consumes by around 2,000 tonnes per furnace per year, says ExxonMobil.

The link to the seventh furnace was timed to coincide with a planned shutdown for maintenance work.
