PhD proposal - LGP2 / LRP. Intensification of gas/liquid mass transfer by ultrasound - application to ozone reactive de-inking and/or bleaching of lignocellulosic fibres with oxygen or ozone.

LGP2 - Thesis proposal

LGP2 - Thesis proposal

The research problem is the use of ultrasound to increasemass transfer in liquid phase of reactive gases used in unit operations of paper processes. Beyond the transfer, the action of ultrasound on the reactivity of these gases and/or on the generation of oxidizing species within the liquid phase will also be investigated. Attention will also be paid on possible interaction between ultrasound and fibres. The objective is therefore the intensification of processes in the aim of improving the overall performances (effluent and fibre quality) while reducing the quantity of reagents used and the environmental impact of discharges.
