METHOD OF REGENERATION OF THE SATURATED SOLUTION OF THE ABSORBENT - TRIETHYLENEGLYCOL

摘要

FIELD: natural gas industry; chemical industry; methods of regeneration of the saturated solutions. ^ SUBSTANCE: the invention is pertaining to the natural gas industry and is intended for usage in the installations of the field preparation of the natural gas for pumping through the main pipeline. The saturated solution of the triethylenrglycol is fed into the regeneration installation. In the tubular furnace it is heated up to the temperature of 207215 with preservation of the single-phase state and provision of its recirculation through the furnace. No more than 30 % of the recycled solution the triethylenrglycol is fed to purification from the impurities and heated up in the furnace of the installation of purification from the impurities to the temperature of 207225. The triethylenrglycol solution purified from the impurities is directed into the installation of the natural gas drying. The invention increases the concentration of triethylenrglycol at its regeneration of above 99 % of the mass, reduces the corrosive effect of the absorbent on the regeneration equipment at preservation of the materials consumption for the installation. ^ EFFECT: the invention increases the concentration of triethyleneglycol at regeneration of above 99 % of the mass, reduces the corrosive effect of the absorbent on the regeneration equipment at preservation of the materials consumption for the installation. ^ 1 dwg, 1 tbl
