Patent ID: 7540887

Claim:
An automated method of making a fuel composition having a maximum Reid Vapor Pressure of 10 psi, comprising: identifying one or more predetermined properties of the fuel composition; charging one or more hydrocarbon feedstock, one or more oxygenate feedstock, and one or more additives into a blending tank to make a fuel composition mixture, each of the one or more hydrocarbon feedstock, one or more oxygenate feedstock, and one or more additive feed having a charge rate; determining amounts of each of the one or more hydrocarbon feedstock, the one or more oxygenate feedstock, and the one or more additives charged into the blending tank to make the fuel composition mixture; determining one or more current properties of the fuel composition mixture in the blending tank, the one or more current properties of the fuel composition mixture corresponding to the one or more predetermined properties of the fuel composition; comparing the predetermined properties of the fuel composition with the current properties of the fuel composition mixture; and adjusting the charge rate of at least one of the one or more hydrocarbon feedstocks, one or more oxygenate feedstocks, and one or more additives into the blending tank in response to the amounts of each of the one or more hydrocarbon feedstock the one or more oxygenate feedstock, and the one or more additives charged into the blending tank and comparing the predetermined properties and the current properties to provide the fuel composition having a maximum Reid Vapor Pressure of 10 psi, wherein adjusting the charge rate is performed using a trained neural network, the trained neural network operative to determine adjustments to the charge rate of at least one of the one or more hydrocarbon feedstocks, one or more oxygenate feedstocks, and one or more additives into the blending tank based upon the current properties of the fuel composition mixture.
