Process for recovering ethylene and vinyl-based comonomer
2016
The present invention relates to a method for recovering ethylene and vinyl-based comonomers which can increase a recovery rate of unreacted monomers remaining after polymerization of ethylene and vinyl-based comonomers; and can increase process efficiency by cost reduction. More specifically, the method for recovering ethylene and vinyl-based comonomers comprises the following steps: a step for polymerizing ethylene and vinyl-based comonomers at a pressure higher than 1500 bar; a step for reducing the pressure of products comprising ethylene and vinyl-based comonomers of the polymerizing step to 0.1-5 bar; a step for adding ethylene to the products of the polymerizing step under the pressure of 0.1-5 bar; and a step for separating the ethylene and vinyl-based comonomers from the products of the polymerizing step to which the ethylene is added.
