ANALYSIS OF THE PROCESS OF DRYING NATURAL GAS WITH GLYCOLS USING AZEOTROPIC SOLVENTS AND MULTIFUNCTIONAL ADDITIVES

Abstract

Abstract: Currently, many gas fields have entered a phase of declining production, which complicates gas preparation in fields, especially in terms of ensuring the quality indicators of natural gas. In order to comply with regulatory requirements for the quality of natural gas supplied to main gas pipelines, it is necessary to improve the calculation, technological and measurement methods for studying the efficiency of gas drying technological equipment. To clarify the thermodynamic methods for calculating the moisture content and dew point temperature for aqueous phases (liquid water, ice and gas hydrate), additional experimental studies of the phase equilibrium in the “natural gas - water - hydrate” system are required. Therefore, the development and improvement of methods for determining the technological parameters of natural gas drying devices is a topical research topic [1]
