1. A method for transporting renewable diesel (RD) through a pipeline, or a portion thereof, the method comprising:
transporting the renewable diesel from a first pipeline terminal to a second pipeline terminal, a first diesel fuel injected prior to a head of the renewable diesel and a second diesel fuel injected subsequent to a tail of the renewable diesel so that when transporting the renewable diesel, the first diesel fuel and the second diesel fuel in combination comprises a minimum volume of 10,000 barrels, the first diesel fuel and the second diesel fuel from the first pipeline terminal to the second pipeline terminal, interfacial mixing occurs, thereby to define a mixed interface fraction stream;
restricting transport in the pipeline to diesel fuel compositions with a first specification, the first specification characterized by a selected amount of the renewable diesel, or a component thereof, the selected amount being less than a selected amount allowed in a second target specification for one or more of the first diesel fuel or the second diesel fuel;
separating, at the second pipeline terminal, a renewable diesel fraction stream, one or more diesel fuel fraction streams, and the mixed interface fraction stream, the mixed interface fraction stream to include a mixture of the renewable diesel and one or more of the first diesel fuel or the second diesel fuel; and
combining at least a portion of the mixed interface fraction stream with at least a portion of the diesel fuel fraction stream, thereby to produce a diesel fuel stream meeting the second target specification.
