Experimental Investigation and Modelling of Asphaltene Precipitation during Gas Injection
(University of Tehran, 2020-12-01)
Due to the limited crude oil resources, the role of enhanced oil recovery (EOR) techniques in the production of the oil that has not been extracted during the primary and secondary oil production techniques is crucial. Gas ...
Estimation of Binary Infinite Dilute Diffusion Coefficient Using Artificial Neural Network
(University of Tehran, 2014-06-01)
In this study, the use of the three-layer feed forward neural network has been investigated for estimating of infinite dilute diffusion coefficient ( D<sub>12</sub> ) of supercritical fluid (SCF), liquid and gas binary ...
Performance of Surfactant-Type Polyoxometalate, [(C16H33)N(CH3)3]6 [PV3W9O40] in Oxidative Desulfurization of Gas Condensate and Straight Run Gasoil
(University of Tehran, 2023-06-01)
A novel hybrid surfactant-type polyoxometalate, [(C16H33)N(CH3)3]6 [PV3W9O40] was synthesized and characterized by FT-IR, SEM and EDX analyze. Oxidation of sulfur compounds in gas condensate with H2O2 as oxidant using ...
The Effect of Preparation Method on the Activity of Bimetallic Ni-Fe Catalyst in Dry Reforming of Methane
(University of Tehran, 2022-06-01)
This paper investigates the effects of Fe/Ni ratio (0.5-2) and polyvinyl alcohol to total metal ratio (PVA/ (Ni + Fe) =0.5-1.5) on the performance of bimetallic(Ni-Fe) catalyst in dry reforming of methane. The activity, ...
Using Artificial Neural Network for Estimation of Density and Viscosities of Biodiesel–Diesel Blends
(University of Tehran, 2015-12-01)
In recent years, biodiesel has been considered as a good alternative of diesel fuels. Density and viscosity are two important properties of these fuels. In this study, density and kinematic viscosity of biodiesel-diesel ...
