Analysis of Efficiency of Natural Gas Absorption Process from Water Impurities

The composition of natural gas varies depending on the field, formation, or reservoir from which it is produced. Since the composition of natural gas is never constant, there are standard test methods that can be used to determine the composition of natural gas and thus prepare it for use. The impurities contained in the gas are led to the formation of hydrates causing the blockage of the pipelines. Determining the optimal technological parameters of the drying plant and recommending a good choice of drying and glycol regeneration process will improve the field gas preparation system. Absorption using triethylene glycol (TEG) is one of the most popular methods for the dehydration of natural gas. However, the thermodynamic parameters of the gas as well as the parameters of the TEG always remain conditions to be studied to ensure an optimization of the process of regeneration of the glycol. The available experimental data were selected and correlated using a thermodynamic model based on the Peng-Robinson equation of state. The results obtained show that the model provided is a valuable tool for the design of the natural gas dehydration process.
