Systems for producing fuel compositions

A system for making a fuel composition having a predetermined first property and a predetermined second property and having reduced emissions of one or more of CO, NOx, and hydrocarbons upon combustion, comprising:

• a blending tank;
• a delivery system comprising flow meters for providing specific amounts of fuel composition components to the blending tank, the delivery system comprising input streams for two or more hydrocarbon feedstocks and one or more oxygenate feedstocks;
• a first property monitor for determining a first property of the fuel composition in the blending tank;
• a second property monitor for determining a second property of the fuel composition in the blending tank;
• a controller for controlling amounts of fuel composition components provided to the blending tank by the delivery system based upon at least the first property and the second property of the fuel composition as determined by the first property monitor and the second property monitor, the controller operatively coupled to the first property monitor, the second property monitor, and the delivery system;
• the delivery system further providing to the controller an amount of each fuel composition component charged into the blending tank;
• the controller configured to recognize the first property of the fuel composition and the second property of the fuel composition as determined by the first property monitor and the second property monitor and stop, start, or alter input streams of the delivery system to obtain a fuel composition having the predetermined first property, the predetermined second property, and having reduced emissions of one or more of CO, NOx, and hydrocarbons upon combustion or a fuel composition having a predetermined first property and predetermined second property closer to the predetermined first property and predetermined second property;
• and
• a memory coupled to the controller for storing information generated by the delivery system, the first property monitor, and the second property monitor, the memory comprising historical information relating to amounts and identities of fuel composition components and corresponding fuel composition properties.
