Abstract
Various systems and processes are directed to filtering organic compounds using nanoporous membranes and osmosis. In various implementations, the nanoporous membrane can be trained on one or more organic compounds such that the nanoporous membrane preferentially allows the one or more organic compounds to permeate the nanoporous membrane to the exclusion of other compounds. In some implementations, the nanoporous membrane is trained on ethanol such that the nanoporous membrane preferentially allows ethanol to permeate the nanoporous membrane to the exclusion of other compounds, such as water or other compounds or mixtures. In some implementations, the selective ethanol permeation of the nanoporous membrane may occur even where the other compounds have smaller molecules than ethanol.
