Abstract: Methods and systems for, among other embodiments, transporting renewable diesel (RD) through a pipeline, or a portion thereof, are provided. In certain embodiments, the method may include transporting the renewable diesel from a first pipeline terminal to a second pipeline terminal, the renewable diesel wrapped head and tail with a compatible diesel fuel. The method may also include restricting the transport of the diesel fuel in the pipeline to diesel fuel compositions having a first composition or first specification, the first composition or first specification characterized by a selected amount of the renewable diesel, or a component thereof, the selected amount being less than the selected amount allowed in a second target specification for the diesel fuel.

Abstract: There is disclosed a formulation for the formation of a black oxide particularly useful in the fabrication of multi-layered printed circuits. The formulation comprises an oxidant and a hydroxide and is characterized by the addition of a water soluble or dispersible polymer to regulate the properties of the black oxide solution.
