The invention relates to the gas industry and can be used for field regeneration of a saturated solution of triethylene glycol, which is used as an absorbent for the extraction of water vapor from gas in installations for the complex treatment of natural gases.

The objective of the invention is to increase the rate of coagulation up to several hours, increasing the efficiency of purification of triethylene glycol from heavy hydrocarbons and reducing the cost of natural gas drying.

The technical result from the use of the proposed method is to obtain regenerated triethylene glycol with a very low content of both water and salt, which allows it to be used again in the technology of natural gas drying. In addition, the reliability of operation of process equipment is increased and operating costs are reduced by reducing the corrosion hazard, reducing production costs for gas production, preventing the recycling of triethylene glycol with improved ecological safety indicators from environmental impact.
