Abstract:
1. An oil processing system, comprising: a deodorizer configured for deodorizing oil and maintained at a pressure of no greater than 10 mm Hg, the deodorizer including a first vapor outlet through which volatilized impurities and a desirable glyceride fraction may exit in a glyceride-rich and impurity-rich vapor stream; a recovery condenser for partial condensation of the glyceride-rich and impurity-rich vapor stream to form a glyceride-rich and impurity-poor recovery fluid, the recovery condenser having a first vapor inlet in fluid communication with the first vapor outlet, a condensing chamber maintained at a pressure no greater than 10 mm Hg, a second vapor outlet through which a glyceride-poor and impurity-rich byproduct vapor stream may exit the condensing chamber, and a recovered fluid outlet through which the glyceride-rich and impurity-poor recovered fluid may exit the condensing chamber; a recovered fluid spray system in fluid communication with the recovered fluid outlet, the recovered fluid spray system including a recovery spray head in fluid communication with the condensing chamber and a recirculation pump positioned to deliver a cooling flow of the glyceride-rich and impurity-poor recovered fluid to the recovery spray head such that additional glyceride-rich and impurity-poor recovered fluid is recovered in the recovery condenser and a substantial fraction of the volatized impurities remain in the glyceride-poor and impurity-rich byproduct vapor stream; and a byproduct condenser having a second vapor inlet and a byproduct condensing chamber maintained at a pressure no greater than 10 mm Hg, the second vapor inlet being in fluid communication with the second vapor outlet and positioned to receive the byproduct vapor stream, the byproduct condensing chamber being configured to condense a substantial fraction of the impurities in the byproduct vapor stream.
