Design of Sulfur Pricing Model with Emphasis on Selling Sulfur to Sulfuric Acid Production Plants

This study attempts to present a pricing model for sulfur, based on the netback pricing method for selling the sulfuric acid to the production plants. Using data of a study presented by the national petrochemical company on sulfuric acid production plant with a capacity of 1.1 million tons in Mahshahr port, the price of sulfur in the price range of acid Sulfuric was set to maintain the project's rate of return, operating profit rate and net profit rate at 25 percent. The results of this study showed that at prices below 1.75 million rials/kg, sulfur should be provided free of charge to sulfuric acid production units in order to reach the rate of 25%. The results also showed that the target sulfur price would be different if the target was to maintain the domestic rate of return, operating profit rate, and the net interest rate at 25 percent. It seems offering a new mechanism for sulfur pricing should be necessary and netback pricing which is presented in this study can be considered one of these new mechanisms.
