Abstract
One or more processes for recovering entrained ionic liquid from a hydrocarbon phase containing droplets of ionic liquid are described. The processes includes contacting the hydrocarbon phase containing the droplets of ionic liquid with a retaining material in a separation zone. The droplets of ionic liquid are retained by the retaining material. The ionic liquid may be recovered from the retaining material with a solvent or desorbent. The retaining material may be regenerated and the ionic liquid may be reactivated. The retaining material may be used in a wash vessel to retain or remove contaminant solids within the reactor or other vessels.
