Amirhossein Khalili-Garakani; Mostafa Jafari

Articles in Press, Accepted Manuscript, Available Online from 17 December 2020

http://dx.doi.org/10.22050/ijogst.2020.254534.1569

Abstract
  In Iran, power plants use liquid fuels such as heavy fuel oil (HFO) or mazut to prevent disruption in power generation. The high percentage of sulfur compounds in HFO and the lack of efforts to remove it, causing significant damage to the environment. The purpose of this research is performing a techno-economic ...  Read More

5. Boosting the Octane Number of Gasoline by Natural Gas Concentrated in Methane

Iqbal Iqbal Hossain

Articles in Press, Corrected Proof, Available Online from 19 December 2020

http://dx.doi.org/10.22050/ijogst.2020.211087.1530

Abstract
  Gasoline obtained from the fractionation of indigenous natural gas condensate has low octane number (78) and is therefore of limited uses. Lead-based octane boosting and catalytic reforming are not the viable methods for many fractionation plants. This study was therefore aimed to develop an inexpensive ...  Read More

6. Experimental Investigation Used of Albizia Julibrissin Extract as a Plant Surfactant on Oil Recovery

Seyed Reza Shadizadeh; Seyed Ramin Seyedi Abandankashi; Siyamak Moradi

Articles in Press, Accepted Manuscript, Available Online from 10 January 2021

http://dx.doi.org/10.22050/ijogst.2021.234857.1555

Abstract
  In recent years, the use of natural surfactants as surface active agents in chemical methods of oil recovery over chemical surfactants has been under consideration due to the absence of environmental problems. In this study, a new plant, Albizia julibressin (Albizia), was introduced as a natural surfactant. ...  Read More
