FIELD: process engineering.
SUBSTANCE: invention can be used at dissolved gas treatment plants to prepare gas for transport in oil-and-gas industry. In glycol reactivation, petroleum ether, 70-100°C-fraction, is fed in amount of 5-25 wt % per glycol into desorber to make an azeotropiser. Petroleum ether, 70-100°C-fraction, is fed in both desorber still and desorber top part for forced circulation.
EFFECT: increase in glycol concentration in reactivation to 99,8-99,9%, and in gas drying depth.
