Abstract

Изобретение относится к способу извлечения серной кислоты из смеси, включающей серную кислоту и углеводороды, в частности углеводы. В соответствии с настоящим изобретением смесь, включающую серную кислоту и углеводы, приводят в контакт с анионоселективной мембраной, получая в результате поток фильтрата, обогащенный серной кислотой, и поток, обедненный по серной кислоте.
