Abstract

Процесс очистки водного раствора серной кислоты, включающий охлаждение водного раствора серной кислоты до температуры замерзания или близкой к ней величины для образования суспензии из твердой фазы и жидкой фазы. Суспензия имеет фракцию с высоким содержанием кислоты и фракцию с низким содержанием кислоты. Фракция с высоким содержанием кислоты отделяется от фракции с низким содержанием кислоты.Отчет о международном поиске был опубликован 1999.04.15.
