Improved operation of head fraction column in acrylonitrile production

Improved operation of head fraction column in acrylonitrile production

A process for the enhanced recovery and oepration of hydrogen cyanide (HCN)/ heads column obtained form the reactor effluent of an ammoxidation reaction of propane, propylene or isobutylene by reducing the polymer formation above the feed tray in the heads tower. 一种通过减少高于头馏分塔进料塔板处聚合物的形成，增强从丙烷、丙烯或异丁烯...

Zusammenfassung:A process for the enhanced recovery and oepration of hydrogen cyanide (HCN)/ heads column obtained form the reactor effluent of an ammoxidation reaction of propane, propylene or isobutylene by reducing the polymer formation above the feed tray in the heads tower. 一种通过减少高于头馏分塔进料塔板处聚合物的形成，增强从丙烷、丙烯或异丁烯氨氧化反应的反应器流出物得到的HCN/头馏分塔的回收和操作方法。
