Vapor–liquid equilibrium of hydrogen–hydrocarbon systems and its effects on hydroprocessing reactors
چکیده انگلیسی


• Literature review of VLE of H2–petroleum fractions for hydroprocessing was done.
• The state-of-art was established and then an analysis of data were provided.
• It was showed the importance of accounting VLE in hydroprocessing reactors.

An exhaustive review of the literature about the vapor–liquid equilibrium (VLE) of hydrogen–hydrocarbon (H2–HC) systems is reported in this work, including studies where reactor modeling is considered or not. Hydrocarbons can be pure compounds or petroleum fractions. Reported petroleum fractions are from gasoline to vacuum residue. The analyzed information was: type of device or cell used to obtain experimental data, model used to predict the VLE behavior, and different options to adjust the EOS by interaction parameters of H2–HC. Comparisons of the ranges of operating conditions (pressure and temperature) of VLE studies with or without reaction were done. The variations of the distribution coefficients of H2 on HC were compared with respect to the pressure. Several of the studies show a strategy used to characterize the oil fraction. It is recognized the importance to consider VLE in the reactor modeling, because it affects the calculation of conversion, depending on the properties of the feedstock and operating conditions. For future work it is recommended to obtain VLE data for H2–heavy petroleum fractions, to development appropriate experimental methods to determine the physical properties of pseudocomponents from heavy petroleum fraction, or mathematical techniques to overcome this deficiency. In addition, the use of analysis of phases’ stability in the VLE is suggested to be sure about the number of phases present in the system to obtain more reliable H2-pseudocomponents interaction parameters.
