Volume 10, Issue 3 , July 2021, , Pages 1-19

http://dx.doi.org/10.22050/ijogst.2021.133532

Abstract
  This study investigated the effect of ethylene-vinyl acetate (EVA) as an inhibitor on wax appearance temperature (WAT) of crude oil in the Iranian oil field using the differential scanning calorimetry (DSC) method. The effect of EVA on the morphology of crude oil wax crystals was examined by a system ...  Read More

The Selection of Amine Solvent in Gas Treating Process Considering Physical and Process Criteria Using Multiple Criteria Decision-making Techniques: A Case Study of Ilam Gas Treating Company

Masoud Seidi; Mohsen Khezeli; Behrouz Bayati; Esmaeil Najafi

Volume 8, Issue 3 , July 2019, , Pages 73-88

http://dx.doi.org/10.22050/ijogst.2017.93209.1396

Abstract
  In the current work, a framework is presented for amine solvent selection in gas treating process. Since the appropriate decision making in this field affects the capital and operational costs, multi attribute decision making (MADM) techniques were used to rank alternatives. The determination of criteria ...  Read More

A Molecular Simulation of Natural Gas Dehydration by 3A Zeolite Nanostructure

behrouz Bayati; Mahmoud Rahmati

Volume 6, Issue 3 , July 2017, , Pages 68-78

http://dx.doi.org/10.22050/ijogst.2018.57856

Abstract
  The adsorption and separation properties of 3A zeolite are investigated by using Grand Canonical Monte Carlo (GCMC) simulation. To obtain the adsorption isotherms of water, methyl mercaptan, and methane on 3A zeolite, COMPASS Force Filed is used. The adsorption isotherms of the pure components and the ...  Read More
