NOVELTY - Providing a blend of biodiesel and diesel fuel in a cold temperature environment, involves blending a portion of the diesel fuel with 100% biodiesel to achieve a first blend of less than or equal to 50% biodiesel, where the diesel and biodiesel are heated to a temperature such that the temperature of the first blend is above the Cloud Point for the first blend; and adding the first blend to unheated diesel fuel to provide a second biodiesel blend.    USE - Used for providing a blend of biodiesel and diesel fuel in a cold temperature environment to produce a bright and clear blend of biodiesel.    ADVANTAGE - The process is carried out at a lower temperature without formation of precipitates. It yields bright and clear product quickly. Only a small portion of the diesel needs to be heated in an in-line heater, thus saving energy cost and expense of providing heated diesel tank.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (A) an in-line method of producing a bright and clear blend of biodiesel in which biodiesel is fuel that is blended into diesel fuel that is below 20degreesF, comprising providing a heated tank of 100% biodiesel and an unheated tank of diesel fuel; moving heated biodiesel through a first conduit (10) from the heated tank to a first injection point; moving unheated diesel fuel through a second conduit (16) to a second injection point; diverting a portion of the diesel fuel into a third conduit (18) prior to the second injection point, where the third conduit comprises an in-line heater (22) and joins the first conduit at the first injection point, and where a first blend is produced at the first injection point, and further where the first blend is at a temperature above the Cloud Point of the first blend; and moving the first blend through the first conduit to the second injection point such that the first blend is blended with the unheated diesel fuel to produce a bright and clear biodiesel blend;    (B) a rack system for blending and loading biodiesel into tank trucks in a cold environment, comprising a heated tank for holding biodiesel; first injection point; second injection point; first conduit providing a fluid connection from the heated tank to the first injection point and comprising a valve for controlling flow of liquid from the heated tank through the conduit; second conduit providing a fluid connection from a source of unheated diesel fuel to the second injection point; third conduit in fluid connection to the second conduit between the source of unheated diesel fuel and the second injection point, connecting the second conduit to the first injection point, and where the third conduit comprises an in-line heater; fourth conduit (26) fluidly connecting the first injection point and the second injection point; fifth conduit fluidly connecting the second injection point with a load arm for loading a biodiesel blend into a tank truck; and automated control system configured to control the concentrations of biodiesel in the blends at the first and second injection points and the temperature of the heated diesel fuel in the third conduit prior to entering the first injection point; and    (C) a biodiesel/diesel fuel blend produced by the above process.    DESCRIPTION OF DRAWING(S) - The figure is a diagram of an in-line blending system for the cold weather delivery of biodiesel/diesel blends.
