Abstract

An accurate prediction of the absorption and desorption of benzene, toluene, ethylbenzene, and xylenes (BTEX) is important for the estimation of BTEX emissions from glycol units in natural gas processing plants. This work presents an approach to accurately model the solubilities of BTEX in triethylene glycol (TEG). The absorption of gases studied in this work into TEG is physical in nature, and therefore, is treated as a physisorption behavior in modeling. The Huang-Radosz version of statistical associating fluid theory (SAFT-HR) equation of state (EoS) was utilized to estimate the solubilities of BTEX in TEG. A new set of SAFT parameters for TEG, as well as a new set of binary interaction parameters between TEG and other components were obtained by fitting experimental vapor pressure and liquid density of TEG and available experimental binary VLE data, respectively. Using these parameters, solubility of multicomponent gases in TEG are accurately predicted. To have an estimation on the relative accuracy of SAFT-HR EoS, the results from Perturbed-Chain SAFT (PC-SAFT) and Peng-Robinson (PR) EoS are also reported. The overall average of root-mean-square deviations (RMSD) for the binary and ternary systems studied in this work, using SAFT-HR, PC-SAFT and PR EoS, were found to be 0. 12, 0. 20 and 1. 56, respectively.
