Nowadays, computational tools for analyzing and collecting data in the operation of petroleum units are essential. One of the methods is the classification or regression is to step in the overall process of knowledge extraction. In this study, one of specific type of decision called the conditional contract arrangement, is used to extract the relevant knowledge in Catalytic Reforming Units (CRU) for 4 factors: Density, PH, total iron ions in vessels (S.FE) and H2S. All of these factors are related to corrosion in CRU and this paper aims to optimize some conditions to eliminate it. In this regard, using ammonium water with a specific range and PH can be helpful. According to the obtained results the best range of density (in Feed) is less than 0.515 kg/m 3 , PH (water in vessels) is more than 6.7, S.FE is less than 1.5 ppm and H2S in recycle gas is less than 700 ppm. 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.

“…In addition, unlike zirconia, they are not vulnerable to hydrogen at hydro Gasoline reaction and have good resistance against sulphur and other catalyst poisons such as nitrogen and oxygen. Another advantage of zeolite-based catalysts is their good capability of restoring [10]. However, since the reaction temperature is between 230 and 270 °C, maximum concentration of the produced isomers (equilibrium concentration) is lower than alumina chloride catalysts.…”

The aim of this study is to investigate naphtha Gasoline unit catalysts. In twofactor catalysts, platinum or palladium was used as the active metal on the base alumina chloride, zirconia, and zeolite. Considering the fact that refining and gasoline processes are expanding and refineries in Iran are required to produce cleaner fuels that meet environmental standards, investigating different kinds of light naphtha gasoline unit catalysts can greatly help to promote production of clean fuel and make production process more efficient. Light naphtha gasoline is normally conversion of normal pentane and normal hexane compounds to its branched compounds. Also Light naphtha its derivatives and it is done by chlorinated ammonia or zeolite catalysts in one or some fixed bed reactors. Activity of two-factor catalysts strongly depends on acidic and metal sites. For example, in catalyst Pt./HY, which is a kind of zeolite catalyst for Gasoline Units, the optimal ratio of strong acidic sites to metal sites in n-heptane Gasoline is determined to be less than 6. In this work, various kinds of catalysts used in isomerization unit were identified and considered.

“…The RSM turbulence model has shown a better thermal volume mixing than other turbulence models. The maximum rate of relative error percentage compared to the experimental data for predicting the temperature in the whole system is less than 6%, which indicates the high accuracy and validity of the calculations and simulation [31][32][33][34]. In 2019, Samimi et al wrote one article about "Use of Data Mining in the Corrosion Classification of Pipelines in Catalytic Reforming Units (CRU)".…”

The catalytic conversion of naphtha is a refinery process in which heavy naphtha feeds through the catalytic bed of several reactors at high temperatures and pressures that potentially increase the aromatics content of naphtha and its octane number. Usually, naphtha feed is used to remove the impurities that prevent useful reactions and cause poisoning of reformer catalysts. Operating abutments for the catalytic converter unit are temperature, pressure, metallurgical agent, hydrogen to hydrocarbon ratio, and chlorine ratio. In this study, Operational Conditions in Octanizer and Hydro-treating Units in oil refinery companies is investigated and optimized the conditions of catalysis.
