RESCO

All 5 Flemish textile coating companies (Concordia Textiles, Plastibert, Seyntex, Sioen Industries and Vetex) use DMF, sometimes in combination with other solvents, in their PU coating processes. For the removal of the solvent gas emissions, the companies use air purification techniques like scrubbers, rotor concentrators and post combustion. In cases where the gas streams have a medium or high load, the efficiency of current technologies is not high enough to reduce the DMF to the required minimum concentrations. The textile coating companies in Flanders are subjected to stricter controls, by the regulation agencies, compared to competitors outside Flanders. The companies need a robust, reliable and efficient emission gas treatment to be combined with their current technique to secure their operations in Flanders.

A feasibility desktop study was already performed. This study screened 16 technologies for this use and concluded that 6 technologies show potential to meet the screening criteria: compatibility with running production systems and installations, (expected) effect and efficiency on removal of DMF, ecological and economical sustainability and “user friendly” (working conditions for operators, etc).

The goal of this project is to study the 6 remaining technologies, first on lab scale en later on pilot scale, to ultimately develop a new purification system that meets the required criteria and reduces the DMF to the minimum concentrations.
