Claim 6:
7. A system for blending gasoline, comprising:
a premium octane pipe capable of flowing a premium octane neat gasoline having an anti-knock index in the range from 88 to 93 and comprising a first valve capable of regulating flow through the premium octane pipe at a known rate;
a regular octane pipe capable of flowing a regular-octane neat gasoline having an anti-knock index in the range from 80 to 87 and comprising a second valve capable of regulating flow through the regular octane pipe at a known rate;
a butane pipe capable of flowing butane and comprising a third valve capable of regulating flow through the butane pipe at a known rate;
an ethanol pipe capable of flowing ethanol and comprising a fourth valve capable of regulating flow through the ethanol pipe at a known rate;
a first analyzer cell connected to the premium octane pipe capable of continually obtaining a premium research octane number and a premium motor octane number;
a second analyzer cell connected to the regular octane pipe capable of continually obtaining a regular research octane number and a regular motor octane number;
a receptacle downstream of the first analyzer cell and the second analyzer cell capable of receiving a gasoline blend comprising the premium octane neat gasoline, the regular octane neat gasoline, the butane and the ethanol;
a programmable logic controller capable of producing the gasoline blend by continuously calculating a volumetric blend ratio of the premium octane neat gasoline, the regular octane neat gasoline, the butane, and the ethanol to produce the gasoline blend,
wherein the calculating of the volumetric blend ratio at least partly depends upon the premium research octane number, the premium motor octane number, the regular research octane number, the regular motor octane number, a predicted value for octane number for the ethanol, a predicted volatility value for the ethanol a predicted octane number value for the butane and a predicted volatility value for the butane,
wherein the programmable logic controller is capable of operating the first valve, the second valve, the third valve and the fourth valve to implement the volumetric blend ratio,
wherein the gasoline blend is a finished gasoline selected from the group consisting of a finished premium octane blended gasoline, a finished mid-grade octane blended gasoline and a finished regular octane blended gasoline.
