Asghar Gandomkar; Bijan Honarvar; Yousef Kazemzadeh; Zeinab Derikvand

Volume 5, Issue 4 , Autumn 2016, Pages 1-17

http://dx.doi.org/10.22050/ijogst.2016.41564

Abstract
  Core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating CO2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. The core samples were provided from a low permeability mixed wet oil reservoir at ...  Read More

3. The Effect of Temperature and Injection Rate during Water Flooding Using Carbonate Core Samples: An Experimental Approach

Yaser Ahmadi; Mehdi Hassanbeygi; Riyaz Kharrat

Volume 5, Issue 4 , Autumn 2016, Pages 18-24

http://dx.doi.org/10.22050/ijogst.2016.41569

Abstract
  In many reservoirs, after water flooding, a large volume of oil is still left behind. Hot water injection is the most basic type of thermal recovery which increase recovery by improved sweep efficiency and thermal expansion of crude.In the present work, the effects of injection rate and the temperature ...  Read More

4. A Novel Technique for Determination of the Onset of Alkane Induced Asphaltene Precipitation Using Accurate Density Measurements

Mahdi Kalantari Meybodi; Jamshid Moghadasi

Volume 5, Issue 4 , Autumn 2016, Pages 25-35

http://dx.doi.org/10.22050/ijogst.2016.41573

Abstract
  Onset of asphaltene precipitation is the key parameter in dealing with asphaltene problems because it is the starting point of the asphaltene separation from the solution. In this study, a new technique is provided based on the experimental observations for the determination of the onset of asphaltene ...  Read More

5. A Numerical Study of the Sour Gas Reforming in a Dielectric Barrier Discharge Reactor

Sajedeh Shahsavari; Alireza Ganjovi; Alireza Ahmadi; Fahimeh Shojaei

Volume 5, Issue 4 , Autumn 2016, Pages 36-52

http://dx.doi.org/10.22050/ijogst.2016.41575

Abstract
  In this paper, using a one-dimensional simulation model, the reforming process of sour gas, i.e. CH4, CO2, and H2S, to the various charged particles and syngas in a dielectric barrier discharge (DBD) reactor is studied. An electric field is applied across the reactor radius, and thus a non-thermal plasma ...  Read More

6. Modeling and Simulation of Kuhni Extraction Column Using a Rate-based Model

Amir Hosein Tahershamsi; Ahad Ghaemi; Mansour Shirvani

Volume 5, Issue 4 , Autumn 2016, Pages 53-67

http://dx.doi.org/10.22050/ijogst.2016.41600

Abstract
  In this study, liquid-liquid extraction process in a Kuhni extraction column was modeled and simulated. A non-equilibrium dynamic model was developed for modeling liquid-liquid extraction processes based on a rate-based model. The model equations are inclusive of partial and ordinary differential equations ...  Read More

7. Anti-corrosive Properties of CeO2 Conversion Coatings on Aluminum Alloy 2024 Prepared by Dip Immersion Method

Niloufar Bahramipanah; Iman Danaee; Maryam Kanani; Mohammad Hosein Maddahy

Volume 5, Issue 4 , Autumn 2016, Pages 68-76

http://dx.doi.org/10.22050/ijogst.2016.41601

Abstract
  As an alternative to chromate conversion coatings, rare-earth coatings especially cerium, because of the low toxicity, have attracted considerable attention. Using dip immersion method, cerium-based conversion coating was deposited on aluminum 2024. Corrosion resistance was studied in 3.5 wt.% NaCl solution ...  Read More
