International technology group ANDRITZ has received an order from Veolia Services Suomi, a Veolia Group company, to supply a biomethanol purification plant.
The plant, which will be integrated into Metsä Fibre’s bioproduct mill in Äänekoski, Finland, refines the crude sulphate methanol generated in pulp production to obtain commercial-grade biomethanol.
The biomethanol purification plant will be designed to produce 12,000 tons of biomethanol per year, making it the world's largest of its kind when it goes into operation. Start-up of the plant is scheduled for 2024. The ANDRITZ delivery to Veolia includes proprietary process design and full EPC delivery, excluding civil works.
The biomethanol purification process is part of the ANDRITZ CircleToZero initiative aimed at achieving zero emissions and zero waste from pulp mills and is a patented extraction process yielding commercial-grade biomethanol. The CircleToZero initiative also offers other next-generation solutions for the chemical recovery cycle of pulp mills, with the target of utilizing pulp mill side streams to the maximum extent possible.
The biomethanol purification plant is a key component in the process for producing sustainable biomethanol from renewable raw material. The fossil-free biomethanol can be used for applications in the pulp mill itself or as a substitute for fossil-based methanol in the transport sector (biodiesel) and as a chemical base substance.
With the world's largest fossil-free biomethanol plant of this kind, Veolia and ANDRITZ’s unique technology are strongly supporting the further development of Metsä Fibre’s unique bioproduct mill approach, which combines efficient raw material use with environmental and energy efficiency. In accordance with the principles of the circular economy, production side streams – in this case, crude sulphate methanol – are utilized and upgraded to obtain products with the highest possible added value.
“Veolia highly values how this industrial partnership has been developed based on a common vision to use natural resources more efficiently and process existing side streams to create new, sustainable bioproducts that can replace fossil-based fuels and materials,” Jacob Illeris, Business Development Director, Veolia Nordic.
