Claim Text:
1. A system for blending butane with gasoline in a pipe, wherein the gasoline has a vapor pressure, comprising: a) a butane reservoir in fluid connection with said gasoline; b) an injector valve for discharging butane into said gasoline; c) a vapor pressure analyzer connected to said pipe, said analyzer configured to determine the vapor pressure of the gasoline and to transmit said vapor pressure to a processor; d) a programmable logic controller governing the flow of butane through said injector valve; and e) a processor programmed to receive the vapor pressure from the analyzer, calculate an amount of butane to inject into the gasoline based on seasonal and/or regional data and a maximum preprogrammed volatility limit, and provide a control signal to said programmable logic controller according to said seasonal and/or regional data and maximum preprogrammed volatility limit; wherein the programmable logic controller is configured to adjust the injector valve to govern the flow of butane through said injector valve into said gasoline based on the signal from the processor.
