CaRPE project - Characterization and remediation of emissions from process based on thermal spraying

High temperature processes related to metal powders (e.g. atomization, thermal spraying) lead to the production and release of metal particles, which are partly nano-sized. There is a lack of knowledge with respect to the properties of these emissions and with respect to their management (collection, confinement or treatments). The CaRPE project aims at bridging the current knowledge gaps in this area. A network of various stakeholders, both form the private as well as the public sector will join their efforts to address current challenges in the field of process engineering, process use, emission risk analysis, metrology and clean process design and support a sustainable development of these technologies.

The CaRPE project want to characterize particles emissions during all the manufacturing line of a coating in thermal spraying: from the powder receipt to the coating cleaning on the final piece. Measurements will be carry on around the process during operation, outside from the spray booth and at filtration system exit. All operators actions will be analyzed: filling/cleaning of the powder feeder, spray booth cleaning, etc.
