Abstract:
1. A system for determining the relative value of a stream of treated naphtha based upon a separately provided PIONA analysis of the fractions of the naphtha after processing in a reformer that is operated at a severity that yields a gasoline product having a predetermined constant research octane number, the system comprising: a memory that stores calculation modules and data; a processor coupled to the memory; a calculation module that calculates the feed quality of the naphtha fractions; a calculation module that estimates the total liquid products variable from the feed quality and the constant research octane number data; a calculation module that estimates raw product yields of methane, ethane, propane, butane and gasoline from the total liquid products variable; a calculation module that determines raw product yields of hydrogen from the total liquid products variable and the predetermined constant research octane number (RON); a calculation module that adds the raw product yields of methane, ethane, propane, butane, gasoline and hydrogen to derive a raw product total yield; a calculation module that normalizes the estimated yields for losses of hydrogen, methane, ethane, propane, butane and gasoline, as a percentage of the raw product total yield; a calculation module that derives the value of the normalized estimated yields of hydrogen, methane, ethane, propane, butane and gasoline by multiplying each normalized estimated yield by a predetermined unit value of each product; and a calculation module that produces and displays an estimated value of the naphtha stream by totaling the values of the normalized estimated yields of hydrogen, methane, ethane, propane, butane and gasoline.
