Abstract

Способ получения чистого триэтаноламина (ТЭА) посредством непрерывного разделения смеси этаноламина, содержащей ТЭА и диэтаноламин (ДЭА), дистилляцией, причём в одной дистилляционной колонне (ДЭА-колонне) отгоняют ДЭА, а полученный поток из куба, содержащий ТЭА, подают в смежную колонну (ТЭА-колонну), в которой чистый ТЭА извлекают в виде потока бокового дистиллята, причём время нахождения этаноламиновой смеси в кубе ДЭА-колонны составляет <20 мин.
