ABSTRACT:
A steam stripping process particularly useful for separating the volatile components of immiscible materials. In the disclosed embodiment of the invention peel oil emulsion, e.g., from a citrus juice extractor, is heated under pressure by the injection of steam while the emulsion is flowing. The major portion of the pressure on the flowing emulsion is then dropped through a back pressure valve, and the resultant vapor-liquid mixture is passed through a long turbulent passage under a slowly decreasing pressure where thorough mixing is provided and d-limonene, the volatile component of the peel oil emulsion, is stripped from the emulsion by the ad-mixed steam. The mixture is discharged at atmospheric pressure into a vapor collecting tank where the spent liquor is separated and drained off. The collected vapors are passed to a condenser, and the condensate therefrom is directed to a decant tank where the d-limonene is decanted off.
