| Abstract: | The composition of vent gas and the effect of the impurity on oxidation reaction in ethylene oxide plant wasdiscussed in this article. The author analyzed the requirement for the spcification of recovering ethylene from vent gas, discussed the development and application of different recovering processes including pressure swing adsorption, membrane separation and adsorption process in China and abroad, and pointed out that with simple process and fine adaptability the pressure swing absorption technology was of good outlook in ethylene recovering processes. |
