Abstract

Описан способ для временного хранения неочищенного акрилонитрила в резервуаре неочищенного акрилонитрила. Способ включает подачу неочищенного акрилонитрила в резервуар для неочищенного акрилонитрила, подачу кислоты в неочищенный акрилонитрил в резервуаре для неочищенного акрилонитрила в количестве, эффективном для поддержания рН ниже целевого рН, и поддержание температуры неочищенного акрилонитрила в резервуаре для неочищенного акрилонитрила ниже целевой температуры.A method is described for the temporary storage of crude acrylonitrile in a tank of crude acrylonitrile. The method includes supplying the crude acrylonitrile to the tank for the crude acrylonitrile, supplying the acid to the crude acrylonitrile in the tank for the crude acrylonitrile in an amount effective to maintain the pH below the target pH, and maintaining the temperature of the crude acrylonitrile in the tank for the crude acrylonitrile.
