FIELD: physics.
SUBSTANCE: method involves absorbing the acrylonitrile vapours from a gas mixture in an absorber column cooled by a refrigeration machine with acrylonitrile, the flow rate of which is set so that the concentration of water vapour in the liquid in the absorber is less than its solubility in acrylonitrile.
EFFECT: effective capturing acrylonitrile vapours, reducing the power inputs and eliminating the restriction on the consumption of the gas mixture.
