Abstract:
1. A facility for collecting a component having higher melting point as compared with other constituent components in a gas, comprising: a collecting tower through which the gas passes, a treating liquid projecting means for projecting treating liquid having temperature controlled to not higher than the melting point of the high melting point component, to the gas in said collecting tower, an extracting means for extracting from inside of the collecting tower a slurry composed of the treating liquid and the high melting point component solidified by contact with the treating liquid, a separation tank in which the slurry extracted from inside of the collecting tower is stored, a melting means of melting the high melting point component solidified in the slurry, and wherein the high melting point component is recovered utilizing a difference in specific gravity of the melted high melting point component and the treating liquid.
