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.

Transporting method and transporting facility for easily polimerizable material

A method for handling an easily polymerizable substance and a device for handling an easily polymerizable substance are provided that prevent polymerization of the easily polymerizable substance in a bypass line by renewing the easily polymerizable substance retained in the bypass line of a flow control valve or flow meter installed in a line through which flows liquid containing an easily polymerizable substance. The method for handling an easily polymerizable substance renews liquid containing an easily polymerizable substance retained in the bypass line by intermittently opening and closing a bypass shutoff valve. The method for handling an easily polymerizable substance allows a portion of a liquid containing an easily polymerizable substance flowing through a line to flow through a bypass line by opening a bypass shutoff valve during handling of a liquid containing an easily polymerizable substance. The flow volume of the liquid containing an easily polymerizable substance that flows through the flow control valve or flow meter is 80% or more of the total flow volume of liquid containing an easily polymerizable substance that flows through the line.
