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

Iqbal Iqbal Hossain; Manos Roy; Abir Debnath

Volume 10, Issue 1 , Winter 2021, , Pages 80-88

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

http://dx.doi.org/10.22050/ijogst.2016.38530

Abstract
  In this paper, exergy and exergoeconomic analysis is performed on the recently proposed process forthe coproduction of liquefied natural gas (LNG) and natural gas liquids (NGL) based on the mixedfluid cascade (MFC) refrigeration systems, as one of the most important and popular natural gasliquefaction ...  Read More

3. A Decision Support System (DSS) to Select the Premier Fuel to Develop in the Value Chain of Natural Gas

Ahmad Mousaei; Mohammad Ali Hatefi

Volume 4, Issue 3 , Summer 2015, , Pages 60-76

http://dx.doi.org/10.22050/ijogst.2015.10376

Abstract
  A value chain is a series of events that takes a raw material and with each step adds value to it. Global interest in the application of natural gas (NG) in production and transportation has grown dramatically, representing a long-term, low-cost, domestic, and secure alternative to petroleum-based fuels. ...  Read More

4. Measurement of Mass Transfer Coefficients of Natural Gas Mixture during Gas Hydrate Formation

Vahid Mohebbi; Reza Mosayebi Behbahani

Volume 4, Issue 1 , Winter 2015, , Pages 66-80

http://dx.doi.org/10.22050/ijogst.2015.8616

Abstract
  In this study, mass transfer coefficients (MTC’s) of natural gas components during hydrate formation are reported. This work is based on the assumption that the transport of gas molecules from gas phase to aqueous phase is dominant among other resistances. Several experiments were conducted on ...  Read More
