Description In the process of natural gas dehydration with the help of diethylene glycol the absorbent obtained after drying is a solution of sodium chloride in the ternary solvent diethylene glycol - water – methanol, because methanol is widely used as a gas hydrate inhibitor and droplets of the gas brine mix with the absorbent. For calculation of the technological mode of operation for gas dehydration systems information on the solubility of sodium chloride in the ternary solvent diethylene glycol – water – methanol is necessary. Sodium chloride solubility in two-component solvent diethylene glycol - methanol and three-component solvent diethylene glycol – water – methanol at the temperature 25С has been studied. In the system investigated, the only liquid phase is formed. The salt solubility increases with the increase in diethylene glycol and methanol content in the three-component solvent. The data obtained can be used in the design of plants for diethylene glycol regeneration from moisture in the conditions of methanol inhibition, as well as in their operation effectiveness analysis.
Изучена растворимость хлорида натрия в двухкомпонентном растворителе диэтиленгликоль – метанол и трехкомпонентном растворителе диэтиленгликоль – вода – метанол при температуре 250С. Растворимость соли падает с увеличением концентрации диэтиленгликоля и метанола в трехкомпонентном растворителе.
