Abstract: Methods are provided for accurately blending biodiesel into distillate streams to achieve a pre-determined percentage of biodiesel in the distillate, applicable to wild-type distillate streams as well as distillate streams that already contain some percentage of biodiesel.
Abstract: Automated methods and systems for blending high sulfur hydrocarbons, particularly those derived from transmix, into low sulfur hydrocarbon streams are provided. Also provided are methods for splitting transmix into usable hydrocarbon fractions and blending the fractions back into defined hydrocarbon streams.
