Abstract
The disclosure relates to methods for distributing alcohol-containing gasoline. The methods herein facilitate the combination of gasoline blendstocks and alcohols to create finished gasoline products. The methods herein also measure the volumes and other characteristics of the gasoline blendstocks and alcohols and employ computers and controllers that calculate the gross and net volumes of liquids, including the net volume of finished gasoline products.
Claims8
A process for distributing alcohol-containing gasoline comprising:
- creating a gasoline blendstock source comprising gasoline blendstock;
- configuring a gasoline blendstock temperature monitor in connection with the gasoline blendstock source to monitor a temperature of the gasoline blendstock and produce a gasoline blendstock temperature measurement;
- flowing the gasoline blendstock through a gasoline blendstock flow meter to measure a net quantity of gasoline blendstock removed from the gasoline blendstock source;
- creating an ethanol source comprising ethanol;
- configuring an ethanol temperature monitor in connection with the ethanol source to monitor a temperature of the ethanol and produce an ethanol temperature measurement;
- flowing ethanol through an ethanol flow meter to measure a net quantity of ethanol removed from the ethanol source;
- creating a distribution point in fluid communication with the gasoline blendstock flow meter and the ethanol flow meter, wherein the gasoline blendstock flowed through the gasoline blendstock flow meter is combined with the ethanol flowed through the ethanol flow meter to create a finished gasoline product at the distribution point;
- regulating the gross quantity of the gasoline blendstock flowed from the gasoline blendstock source to the distribution point and the gross quantity of ethanol flowed from the ethanol source to the distribution point via a control system in connection with the gasoline blendstock flow meter and the alcohol flow meter, wherein the control system comprises a volume correction computer that comprises a processor and memory containing program code, wherein the program code comprises instructions that calculate a net volume of the finished gasoline product created at the distribution point based on the gross quantity of gasoline blendstock, the gross quantity of ethanol, the gasoline blendstock temperature measurement and the ethanol temperature measurement, wherein the instructions account for the temperature-dependent volumetric expansion of finished gasoline blends comprising a mixture of gasoline blendstock and ethanol;
- generating an invoice based on the net volume of finished gasoline product wherein the net volume of finished gasoline product is larger than the gross volume of the sum of the net quantity of gasoline blendstock and the net quantity of ethanol.
