Many of the conventional separation and purification processes in oil and gas, chemical, and pharmaceutical industries utilise large quantities of organic solvents and entail high energy consumption.[1] Such processes could be totally or partially replaced by membrane technology, with an order of magnitude lower energy consumption. To enable this, membranes need to be both chemically resistant to the solvents involved and provide high flux, in order to process large solvent volumes with a viable area and in a viable timeframe.
