The distillery generates in the region of 90,000 tonnes of waste products annually, which will be used to generate 5.5 MW of electricity.
The distillery effluent, which is a mixture of wheat, malted barley, yeast and water, is processed through a belt press to remove the biomass that is combusted to generate heat and electricity for the distillery.
While the extracted aqueous liquid is treated in an anaerobic digester to produce biogas as a secondary fuel for the boilers.
The boilers produce superheated steam at approximately 60 bar pressure, which drives the first stage of the steam turbine to produce electricity.
The steam, now at a reduced pressure of 16 bar, then drives the second stage of the steam turbine and is also tapped off and sent into the main plant, where it is used in the distillation process.
Veolia designed the plant, while BCI Process was responsible for the stainless steel pipework linking the process plant packages and vessels, as well as providing the design and construction of the support structures and gangways.
The project is expected to generate approximately 80% of the electricity and 98% of the steam requirement of the distillery.
