(54) СПОСОБ ОЧИСТКИ ОБОРУДОВАНИЯ ОТ КАРБОНАТНЫХ ОТЛОЖЕНИЙ (57) Изобретение относитс к энергетике и позвол ет интенсифицировать процесс и утилизировать отходы. Очищаемую поверхность обрабатывают 515%-ным по основному веществу раствором гидроксихлорида алюмини , в который перед обработкой добавл ют отходы высококип щей фракции производства морфолина следующего состава мас.%: диэтиленгликоль 30-50, аминоiсодержащие смолы 40-70 в количестве 1000-2000 мг/л. 2 табл.(54) METHOD FOR CLEANING EQUIPMENT FROM CARBONATE DEPOSITS (57) The invention relates to energy and allows to intensify the process and dispose of waste. The surface to be cleaned is treated with a 515% basic substance aluminum hydroxychloride solution, to which, before processing, waste of the high boiling fraction of morpholine production of the following composition is added, wt%: diethylene glycol 30-50, amino-containing resins 40-70 in the amount of 1000-2000 mg / l . 2 tab.
Изобретение относитс к способам очистки оборудовани от карбонатных отложений и может быть использовано дл отмывки оборудовани в теплоэнергетике .The invention relates to methods for cleaning equipment from carbonate deposits and can be used for cleaning equipment in a power system.
Целью изобретени вл етс интенсификаци процесса и утилизаци отходов .The aim of the invention is to intensify the process and utilize the waste.
Карбонатные отложени из теплообменников нефтеперерабатывающего завода и теплопередающих устройств ГРЭС в проточных услови х при температуре 20 и 50 С подвергают воздействию основными хлоридами алюмини с концентрацией от 5 до 15% по основному веществу (по известному способу ), а также растворами основных хлоридов алюмини с добавкой отхода высококип щей фракции производства морфолина..Carbonate deposits from heat exchangers of an oil refinery and heat transfer devices of a state district power station under flow conditions at a temperature of 20 and 50 C are exposed to basic aluminum chlorides with a concentration of 5 to 15% of the basic substance (by a known method), as well as solutions of basic aluminum chlorides with added waste high-boiling fraction of morpholine production ..
Скорость растворени карбонатных отложений дана в табл. 1.The rate of dissolution of carbonate sediments is given in Table. one.

Образцы Ст. 3 подвергают коррозионному воздействию указанньми растворами при температурах 20 и 50°С.Samples Art. 3 is subjected to the corrosive effects of the indicated solutions at temperatures of 20 and 50 ° C.
Скорость коррозии испытываемых образцов представлена в табл. 2.The corrosion rate of the tested samples is presented in table. 2

Как видно из табл. 2, добавка отхода высококип щей фракции производства морфолина к раствору гидроксихлорида алки4ини ускор ет растворение отложений и уменьшает степень коррозии в три раза. Кроме того, применение ранее неиспользуемых отходов производства морфолина способбтвует охране окружающей среды.As can be seen from the table. 2, the addition of waste of the high-boiling fraction of morpholine production to the solution of alkyl 4-hydroxychloride accelerates the dissolution of deposits and reduces the degree of corrosion by three times. In addition, the use of previously unused morpholine production waste contributes to environmental protection.
