Abstract

In this work we present a model for predicting hydrate formation condition to separate carbon dioxide (CO2) from different gas mixtures such as fuel gas (H2+CO2), flue gas (N2+CO2), and biogas gas (CH4+CO2) in the presence of different promoters such as tetra-n-butylammonium bromide (TBAB), tetra-n-butylammonium chloride (TBAC), tetra-n-butylammonium fluoride (TBAF), tetra-n-butyl ammonium nitrate (TBANO3), and tetra-n-butylphosphonium bromide (TBPB). The proposed method was optimized by genetic algorithm. In the proposed model, hydrate formation pressure is a function of temperature and a new variable in term of Z, which used to cover different concentrations of studied systems. The study shows experimental data and predicted values are in acceptable agreement.
