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...
