Method and system for blending gasoline and butane at the point of distribution

A method for blending gasoline and butane comprising:

• drawing a gasoline stream from a tank of gasoline;
• drawing a butane stream from a tank of butane;
• blending the butane stream and the gasoline stream to form a blend;
• and
• dispensing the blend to gasoline transport vehicles using a rack.

A system for blending gasoline and a volatility modifying agent comprising:

• a tank of gasoline;
• a tank of the volatility modifying agent;
• a blending unit downstream of and in fluid connection with the tank of gasoline and the tank of the volatility modifying agent;
• and
• a rack downstream of and in fluid connection with the blending unit, wherein the rack is adapted to dispense gasoline to a gasoline transport vehicle.

A method for blending gasoline and a volatility modifying agent comprising:

• drawing a gasoline stream from a tank of gasoline;
• drawing a volatility modifying agent stream from a tank of the volatility modifying agent;
• blending the volatility modifying agent stream and the gasoline stream to form a blend;
• and
• dispensing the blend to a gasoline transport vehicle at a rack.

A computer-implemented method for blending a butane stream with a gasoline stream comprising the steps of:

• receiving a first measurement indicating a vapor pressure of the gasoline stream;
• receiving a second measurement indicating a vapor pressure of the butane stream;
• calculating a blend rate at which the butane stream can be blended with a gasoline stream;
• and
• transmitting an instruction to a programmable logic controller for adjusting the butane stream to the calculated blend rate for blending with the gasoline stream and distributing at a rack.

A computer-implemented method for blending a volatility modifier stream and a gasoline stream comprising the steps of:

• receiving a first measurement indicating a vapor pressure of the gasoline stream;
• receiving a second measurement indicating a vapor pressure of the volatility modifier stream;
• calculating a blend rate at which the volatility modifier stream can be blended with the gasoline stream;
• and
• transmitting an instruction to a programmable logic controller for adjusting the volatility modifier stream to the calculated blend rate for blending with the gasoline stream and distributing at a rack.
