Title:
易重合性物質取扱方法および易重合性物質取扱装置
Document Type and Number:
Japanese Patent JP4481010
Kind Code:
B2
Abstract:
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.
