To provide e.g. a method of removing high-melting-point additives, with respect to methods and equipment for removal of high-melting-point compounds and methods and equipment for recovery of solvents.
The reducing agent removal line 51 has a heat exchanger 100, an air supply line 101 and a cleaning solution supply line 102. The cleaning solution supply line 102 supplies a cleaning solution 321 to the first passage chamber 111. The air supplying line 101 supplies, to the first passage chamber 111, the mixed air 402 consisting of a dried air 301 containing a high-melting-point additive and an additive containing air 401 containing a low-melting-point additive. The contact of the mixed air 402 with the heat exchanger element 114 causes a mixture containing the high-melting-point additive to precipitate from the mixed air 402. Because the melting point MP1 of the high-melting-point additive in the mixed air 402 can be adjusted to be lower than the temperature of the cleaning solution by adjusting the mixing ratio M, the cleaning solution 321 dissolves the precipitation when the precipitated mixture comes in contact with the cleaning solution 321, resulting in cleaning waste water 320. The reducing agent removal line 51 can remove the high-melting-point additive easily from the dried air 301.
