Abstract

The present invention aims to provide a transfer method and a transfer facility for an easily polymerizable substance that limits standing retention of the easily polymerizable substance in the feed pump, etc., and the generation and adherence of solid matter such as polymer or precipitate that accompanies such retention, in a facility in which respective feed pumps are disposed at the plurality of passages that branch off at the easily polymerizable substance inflow side and converge at the easily polymerizable substance outflow side. In this easily polymerizable substance transfer method, in the case where one feed pumpoperates and the other feed pumpis stopped, a portion of the easily polymerizable substance is fed to feed pumpand second passagein a direction that is opposite to the direction of flow of the easily polymerizable substance when feed pumpis activated. In this easily polymerizable substance transfer facility, a check valveprovided downstream to feed pumphas a hole in the valve plug that permits passage of the easily polymerizable substance.
