Valmet has signed a contract with Circa to supply a pyrolyzer plant for the production of sustainable biochemicals at Circa’s ReSolute plant in France. Valmet’s delivery includes pyrolyzer technology, a circulating fluidized bed (CFB) boiler and an automation system. The ReSolute plant will produce 1,000 tonnes of bio-based solvent called CyreneTM per year. It is used to replace fossil petroleum-based solvents used in a wide variety of industries.
The order is included in Valmet’s orders received of the fourth quarter 2022. The value of the order will not be disclosed. The equipment deliveries are scheduled for the second and the third quarter 2023.
“Our co-operation with Valmet has reached the first commercial milestone. We expect to continue the co-operation to reach our goal of producing 80 000 tonnes of Cyrene annually by 2030. Valmet’s concept for integrating the pyrolyzer and the energy production provides major savings in plant operating costs,” says Tony Duncan, CEO of Circa Group.
“We are actively developing technology to replace fossil raw materials with renewable ones. We are working with various applications for our pyrolysis technology. Together with Circa we have tested the biochemicals production process in various pilot trials. In this project we have combined our experience in other thermal conversion processes with our know-how in automation. This is an excellent example of widening our product portfolio into new technologies,” says Ari Saario, Vice President, Strategy and R&D, Pulp and Energy, Valmet.
This order is a continuation of the cooperation agreement signed in May 2022. The long-term objective is to develop deployable modules with a capacity of 10–15 thousand tonnes per annum.
Technical details about the delivery
Valmet’s delivery includes a Valmet Pyrolyzer system, a Valmet CFB boiler and a Valmet DNA Automation system. The pyrolyzer system has a capacity of 2 tonnes dry solids per hour, and produces raw material for Circa’s further distillation and hydrogenation processing. The CFB boiler, with a capacity of 10 MW fuel, produces energy for the pyrolyzer, the biomass dryer and for the distillation. The plant can produce its own thermal energy by utilizing pyrolyzer side product, biochar, in the CFB boiler. The Valmet DNA automation system covers the whole plant enabling optimization of the complete process.
