Evonik Industries recently started operating a thin-film composites plant to coat membranes for use in organic solvent nanofiltration and gas separation at its Marl site in Germany.
Evonik is a global leader in the area of organic solvent nanofiltration, a technology for particularly effective material separation in organic solvents. The Group’s hydrophobic polyimide membranes, sold under the brand names DuraMem and PuraMem, are used in processes such as the efficient recovery of valuable homogeneous catalysts, solvent recycling or gentle processing of natural oils.
In the new thin-film composite plant, thin membrane films are coated with special silicone or other materials. The resulting composite membranes are then turned into solvent-resistant or gas-tight spiral-wound modules in a further production process. The corresponding silicone coating, also manufactured by Evonik, is a key factor for the separation properties of the membrane.
The start-up also marked the production launch of the third generation of DuraMem and PuraMem membranes. Their market introduction is planned for the second half of the current year.
