New numerical model for solubility of light alkanes in triethylene glycol

摘要

A new numerical model, which covers the full range of dehydration-plant operating conditions and wide range of experimental data results, estimates the amount of CH_4, C_2H_6 and C_3H_8 absorbed per volume of triethylene glycol (TEG) circulated vs. the partial pressure of light alkanes and the absorber temperature. This article shows that the proposed numerical approach is more accurate than routine equation of states in predicting the solubility of light hydrocarbons in TEG This article also provides comparisons between the results of the proposed model with experimental data and an equation of state results.
