A system and a method for determining the relative value of a naphtha product includes reforming the naphtha into fractions at a predetermined constant research octane number (RON), conducting PIONA analysis on the reformate, after which modules or steps are performed to assign the feed quality, assign the total liquid yields, assign raw product yields, normalize the assigned raw product yields, assign a value to one or more fractions, and calculate a total value of the naphtha stream. The method is repeated on samples of different crude oils in order to provide relative values at the predetermined RON for comparison purposes. |

1. A system for assigning a value to a naphtha sample based upon naphthene and aromatic content of a reformate fraction of the naphtha sample at a target research octane number, the system comprising:
a non-volatile memory device that stores calculation modules and data, the data including naphthene and aromatic content of the reformate fraction; a processor coupled to the memory; a first calculation module that calculates and assigns a total products yield as a function of the naphthene content, the aromatic content and the target research octane number; a second calculation module that calculates and assigns raw product yield to each of methane, ethane, propane, butane and gasoline as a function of the assigned total liquid products yield; a third calculation module that calculates and assigns a raw product yield of hydrogen as a function of the assigned total liquid product yield and the target research octane number; and a fourth calculation module that calculates and assigns values to each of hydrogen, methane, ethane, propane, butane and gasoline as a function of the raw product yields of each of hydrogen, methane, ethane, propane, butane and gasoline and a unit value of each product. |
