More Information
Summary:Metal-containing ionic liquids can demonstrate a sharply increased viscosity relative to the same ionic liquids without the metal cation. Metal-containing ionic liquid compositions are disclosed that contain viscosity modifiers that reduce viscosity. Metal-containing ionic liquids are applicable to methods and within systems designed for the purpose of removing and recovering certain components of process streams such as ethylene, isobutane, or both. Methods for removing and recovering ethylene from process streams are also disclosed herein as having increased ethylene removal capacity concurrently with reductions in viscosity without corresponding reductions in metal cation concentrations.
