Description

.(54) СПОСОБ ИЗВЛЕЧЕНИЯ СЕРНОЙ КИСЛОТЫ. (54) METHOD FOR EXTRACTING SULFURIC ACID

сульфированного керосина в копичестве SOO МП/час .Извлечение сеоной кислоты ведут на t ступен х. При этом в рафйнате остаетс  О,О5 М серной киспоты.sulfonated kerosene in the amount of SOO MP / hour. The removal of seonic acid is carried out at t steps x. At the same time, O, O5 M sulfuric acid remains in the raffinate.

Поаученаый экстракт в копичестве 500 мл/час, содержащий 0,9 м серной кислоты, подают на реэксгракцию в последующий 12-ступенчатый смеситепь-отстойник. В реэкстрактор подают 2ОО мп/час воды. Полученный реэкстракт содержит 1М серной кнспоты.а оборотный экстрагент содержит 0,5 М серной киспоты.A scouted extract in the amount of 500 ml / hour, containing 0.9 m of sulfuric acid, is fed for re-extraction into a subsequent 12-stage mixing tank. In the extractor serves 2OO MP / hour of water. The resulting reextract contains 1M sulfuric concentrate. And the reverse extractant contains 0.5 M sulfuric acid.
