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