To control power consumption and the cost of equipment by dispensing with a vacuum pump and a condenser of the heart of operation.
An apparatus for recovering a volatile substance in a high-viscosity polymerization fluid comprises a flash drum 1 whose inside can be pressure-reduced, a shell and tube heat exchanger 2 which is installed on the upper part of the flash drum and has a number of tubes 5 where a fluid to be heated flows or a plate heat exchanger, a jet condenser 9 for introducing a volatile substance B volatilized and separated from a high-viscosity polymer fluid P in the flash drum, a pot 12 for recovering a condensed fluid C condensed in the jet condenser, a condensed fluid circulation channel 31 for supplying the condensed fluid in the pot to the jet condenser as a working fluid, a circulating pump 32 provided in the condensed fluid circulation channel, and a cooler 33 provided on the downstream side of the circulating pump.
