[ 1 ] - مدلسازی ریاضی جداسازی دی اکسید کربن از مخلوط گازی نیتروژن و دی اکسید کربن توسط تماس دهنده غشایی الیاف توخالی پلی پروپیلن در حضور محلول آمین ها
در این مقاله مدلسازی ریاضی دفع دی اکسید کربن از مخلوط گازی نیتروژن و دی اکسید کربن در حضور آمین ها در یک تماس دهنده غشایی الیاف تو خالی پلی پروپیلن بررسی می شود. مدلسازی در هر دو جهت شعاعی و محوری بر مبنای حالت کاملاً مرطوب برای جریان غیرهمسوی گاز-مایع مورد بررسی قرار می گیرد. برای ارزیابی مدل، نتایج حاصل از این مدلسازی با داده‌های تجربی و نتایج حاصل از نرم افزار COMSOL با یکدیگر مقایسه می ش...
[ 2 ] - Sand Production Control in Sandstone Reservoirs Using a Modified Urea-formaldehyde Re
Several techniques have been used for sand production control in sandstone reservoirs.The main objective of this research is to present a suitable resin to be used as a consolidation agent in oil reservoirs. To achieve this purpose, urea-formaldehyde resin, phenol-formaldehyde resin, and modified urea-formaldehyde resin were selected to be studied. Core samples were made by the sand sample prov...
[ 3 ] - A Novel Study of Upgrading Catalytic Reforming Unit by Improving Catalyst Regeneration Process to Enhance Aromatic Compounds, Hydrogen Production, and Hydrogen Purity
Catalytic reforming is a chemical process utilized in petroleum refineries to convert naphtha, typically having low octane ratings, into high octane liquid products, called reformates, which are components of high octane gasoline. In this study, a mathematical model was developed for simulation of semi-regenerative catalytic reforming unit and the result of the proposed model was compared with ...
[ 4 ] - Conversion and Residence Time Calculation for Gas-solid Solid Reactions of the Cylindrical-shaped Particles with Con-stant Size Using the Shrinking Core Model
In this paper, a mathematical model is developed to calculate the conversion and the residence time reaction for plug flow and mixed flow in the reactors filled with cylin-drical particles using the shrinking core model. In this modeling, the size of the particles is un-chamged during the reaction. Also, the reaction rate is controlled by the gas layer resistance, the ash layer resistance, and ...
[ 5 ] - Mathematical Modeling of Carbon Dioxide Removal from the CO2/CH4 Gas Mixture Using Amines and Blend of Amines in Polypropylene: A Comparison between Hollow Fiber Membrane Contactor and Other Membranes
In this work, a mathematical model is established to describe the removal of CO2 from gaseous mixtures including CH4 and CO2 in a polypropylene hollow fiber membrane contactor in the presence of conventional absorbents such as monoethanolamine (MEA), methyldiethanolamine (MDEA), and a blend of them. Modeling was performed in axial and radial directions under the fully-wet condition for counterc...
[ 6 ] - Optimization of Semiregenerative Catalytic Naphtha Reforming Unit to Enhance Octane Number and Reformate Yield
Catalytic naphtha reforming is one of the most important processes in which, low quality naphtha is converted into high octane motor gasoline. In this study, a mathematical model was developed and was used for investigation the effect of temperature, pressure, hydrogen to hydrocarbon ratio on the octane number, the yield of product and the undesirable phenomena of coke deposition in a semiregen...

[ 8 ] - Nelder-Mead algorithm optimization and Galerkin’s method thermal performance analysis of circular porous fins with various profiles in fully wet conditions
The main objective of this research is to analyze optimization and the thermal performance of circular porous fins with four different profiles, rectangular, convex, triangular and concave under fully wet conditions. In this research, a linear model was used for the relationship between humidity and temperature. Also, modeling is assumed one-dimensional and the temperature changes only in the d...
