Abstract: The method for the acrylonitrile or methacrylonitrile regenration produced from the reactor flow in the amoxidation of propylene or isobutylene includes admission of the reactor flow across an absorption, regeneration and desorption column. The maximum pressure in the regeneration column is increased mechanically by about 0.00018 to 0.035 mPa in order to improve the hydraulic capacity of the regenration and desorption column. 8 claims
