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

This article presents experimental results on the effect of azeotropic solvents and polyfunctional additives in the drying of natural gas with glycols. The addition of hydrocarbon azeotropic solvents to the glycol recovery system increases the TEG concentration and reduces the moisture content of the glycol. The addition of azeotropic solvents to the glycol recovery system increases the concentration of TEG and reduces the viscosity of the glycol. A regeneration scheme has been developed by adding 0.10-0.30 kg of petroleum ether per 1 kg of glycol to a desorber in an absorption drying apparatus for natural and satellite gases.
