Williams Pipe Line Co. developed an economically feasible method for transporting batches of immiscible No. 2 fuel oil and UAN fertilizer solution (ammonium nitrate, 45%; urea, 35%; and water, 20%) in a single pipeline by employing the head-end sequence of No. 2 fuel oil, pig (to separate batches), emulsion zone consisting of fuel oil and water, pig, water, UAN, water, pig, emulsion zone, pig, fuel oil, and pig within fuel oil to limit water contamination of the oil. At destination, oil is recovered after it settles out of stored hazy fuel oil, emulsion, and water buffer. UAN contamination of oil is detected by checking for ammonia nitrogen, but contamination is minimized by the proper positioning of the pigs. Problems with this technique, including the tendency for the heavy UAN to form contaminating slugs, the impossibility of shipping UAN pipeline in winter due to water freezing and to salting out of UAN solutions, and incompatablity of corrosion inhibitors in UAN and in fuel oil, are discussed.
