The method of combining two or more fuels in specific quantities to achieve a desired blend. There are two customary methods of blending: ratio and sequential. Ratio blending is the method of combining the fuels in the flowstream at predetermined percentages, for example: 90% gasoline/10% ethanol. Sequential blending is the method of loading out the fuel in predetermined quantities that make up the percentages, for example: 900 gallons of gasoline (90%)/100 gallons of ethanol (10%). Sequential blending is usually referred to as “splash” blending. Splash blending is not always an accepted method of blending as it lacks true control and verification.
