Volume 8, Issue 3 , Summer 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

Volume 6, Issue 3 , Summer 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
