СПОСОБ РЕГЕНЕРАЦИИ НАСЫЩЕННОГО РАСТВОРА АБСОРБЕНТА - ДИЭТИЛЕНГЛИКОЛЯ

摘要

FIELD: natural gas industry; chemical industry; methods of regeneration of the saturated solution of the absorbent- diethyleneglycol. ^ SUBSTANCE: the invention is pertaining to natural gas industry and is intended for usage in the installations of the field preparation of the natural gas for transportation through the main pipeline. The saturated solution of diethyleneglycol is fed into the regeneration installation. In the tubular furnace it is heated up to the temperature of 165185 with preservation of its single-phase state and provision of its recirculation through the furnace. No more than 30 % of the regenerated solution of the diethyleneglycol is fed for purification of the impurities and heated up in the furnace of the installation of purification from the of impurities up to the temperature of 165210. The purified from the impurities solution of diethyleneglycol is directed into the installation of the gas drying. The invention increases the concentration of diethyleneglycol at regeneration above 99 mass %, reduces the corrosive effect of the absorbent on the regeneration equipment at preservation of the materials consumption for the installation. ^ EFFECT: the invention ensures the increase of the concentration of the diethyleneglycol at the regeneration process exceeding 99 mass percent, the decrease of the corrosive effect of the absorbent on the regeneration equipment, preservation of the materials consumption for the installation. ^ 1 dwg, 1 tbl
