  • Patent number: 4569755
    Abstract: This invention relates to a low energy process for the solvent extraction of aromatic hydrocarbons from hydrocarbon streams containing the same, using as the solvent N-cyclohexyl-2-pyrrolidone together with small amounts of water. This solvent may be recovered from the aromatics by cooling the aromatic/solvent mixture, and adding water, whereby separation takes place without distillation. The solvent may then be separated from the water by heating the solvent/water mixture.
