(598c) 3D-Printed Membranes for Multiphase/Multicomponent Liquid Separation

A 3D-printed membrane device with multiple selectivity has been developed for multiphase/multicomponent liquid separation. Here miscible liquid mixture is separated by solid-supported ionic liquid membrane (SILM). Immiscible liquid mixture is separated by 3D-printed hydrophilic/oleophobic membrane (HOM). On demand integration of the two membranes into the device via 3D printing provides the desired multiple selectivity for a given liquid mixture. numbering scallop is enabled by mass produced interconnecting pieces similar to LEGO construction techniques. Continuous separation operation will reduce the footprint of the device. As an intensified process it will potentially replace conventional many-step operation, including distillation and extraction, and significantly lower te energy and capital cost.
