Abstract

Устройство содержит колонну, содержащую верхнюю, среднюю и нижнюю секции. Средняя секция сконструирована для приема первого потока, содержащего акрилонитрил, HCN, ацетонитрил и воду. Колонна сконструирована для дистилляции первого потока и получения из первого потока второго потока, причем второй поток содержит воду, по существу, не содержит ацетонитрил. Колонна сконструирована для получения третьего потока в верхней секции колонны, причем третий поток содержит акрилонитрил, HCN и часть воды из первого потока. Колонна содержит зону концентрирования неочищенного ацетонитрила, определенную перегородкой и внутренней поверхностью стенки колонны. Колонна сконструирована для получения в верхнем объеме зоны потока, содержащего воду и ацетонитрил и, по существу, не содержащего акрилонитрил и HCN.
