Monomers recovery. The latex created in polymerization reactors is flashed at atmospheric strain after which under vacuum. Residual butadiene vapors are compressed after which cooled for condensation. The con-densed stream is directed to the decanter for h2o removal. Recovered butadiene is recycled to some butadiene plant, in which butenes are separated, so the recovered butadiene is usually reused in the NBR latex plant.
