Abstract

Increasing the capacity of Gasoline Production Plant (G.P.P) will cause problems such as the increase of pressure downfall, reduction of output pressure of circulating gas compressor, increasing the thermal load of the re-boiler furnaces of unit towers, increase of the eventuality of formation green oil in vessels, increase of the eventuality of coke formation on the catalyst and eventually reducing the catalyst life span. In this research, operating conditions have been investigated that indicates the increase of the petrochemical feed with the design capacity of 71,000 barrels per day, to the 75,000 barrels per day. The results indicate that with increasing feed, the entrance temperature and pressure to the unit reactor should be increased. According to the obtained results the best temperature (in Feed) is 525 °C, output pressure of circulating gas compressor is more than 22 ton/hr and the circulation of catalysis range is 750-950 kg/hr, the Octane Number will be a Constant Rate 95 and the amount of Coke Formation in all Conditions 3.5-4.3%. The outcomes also show how this approach can be used to gain insight into some refineries and how to deliver results in a comprehensible and user-friendly way.
