Study of Operational Conditions in Octanizer and Hydro-Treating Units in Oil Refinery Company

“…In this model, the reactants were divided into 10 false units. The primary components consisted of three main groups of paraffin's, naphthenes and aromatic compounds, and hydrogen and ethane and propane and butane were considered as separate components [21]. One year later, Mr. Krane presented another model that included the initial raw material consisting of 20 false elements and hydrocarbons 8 to 10 carbons in the form of 53 reactions.…”

“…In this research, a new process design for optimization was proposed by analyzing various reforming technologies. The basis of this scheme was the separation of benzene from the reaction mixture before entering the second reactor, which resulted in the benzene rate reduction in the final reformate product [21]. In the same year, HOU Weifeng et al provided a model containing 18 new kinetic equations for naphtha catalytic conversion process reaction by using Aspen Plus software as a functional module for process simulating and developing and expanding this model and optimizing it.…”

Enhanced BTX Production in Refineries with Sulfur Dioxide Oxidation by Thermal Integrated Model

“…In addition, Taskar et al developed a rigorous mathematical model for a semi‐regenerative naphtha reformer, while, Liang et al expressed a physical model to describe the catalytic reforming reactors with radial flows. The prediction of duration of the operating cycle between regenerations periods and the optimization of the conditions of treatments to increase the efficiency of industrial unit operation were accomplished by Kvartsov et al . Also, the pyrolysis performance of catalytic cracking of naphtha process and coke formation on active catalysts was investigated by Liu et al .…”
