Optimization of the Gasoline Production Plant in order to Increase Feed

Abstract

One of the most important process in refineries is Naphtha catalytic conversion. In this process, gasoline with high octane number produce in the petrochemical complexes of precious aromatics such as benzene and toluene. 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 in north hemisphere. 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.

“…Myoglobinuria is pathognomonic of rhabdomyolysis, and evidence suggests that myoglobin disrupts glomerular filtration through several mechanisms, including intrarenal vasoconstriction, ischemic tube injury, and tubular obstruction [30][31][32]. Jin and Tang reported a 60-year-old man with COVID-19, who developed lower extremity pain and weakness and rhabdomyolysis on the ninth day of hospitalization [32]. Rhabdomyolysis is the breakdown of skeletal muscle myocytes and the release of intracellular contents.…”

“…We still have a lot of unfinished business about the new coronavirus and its disease. Therefore, the publication of real-time analyzes obtained from real scientific information at this time is even more necessary [32][33][34][35]. Therefore, considering the significant importance of this disease and its significant spread in the world that has been published so far about the epidemiology and strategies to combat this disease (Figure 3) [36].…”

Remoção de gasolina por um consórcio microbiano anaeróbio em um solo argiloso / Removal of gasoline by an anaerobe consortium in a clayey soil

“…A gasolina é um produto obtido a partir do refino do petróleo, cuja composição depende, principalmente, de sua aplicação (SAMIMI et al, 2020). As gasolinas automotivas são constituídas por hidrocarbonetos com quatro a doze átomos de carbono (RIBEIRO; SCHIRMER, 2017) e no Brasil é comercializada misturada ao etanol (Policarpo et al, 2018).…”
