ている。Therefore, alcohols contained in such gases,
Various methods have been proposed for recovering fluorocarbon-based solvents and the like. Specifically, for example, water is used as a liquid to adsorb the solvent and removed by a device such as a scrubber, or a gas containing the solvent is passed through a layer of activated carbon, the activated carbon is then regenerated by steam, and the steam is then removed by a condenser. There are known methods of liquefying the solvent and recovering the solvent as a liquid.

が生じる。However, in order to recover the solvent contained in the gas using water using the scrubber, a distillation process is required, which increases the cost and has a low recovery efficiency for water-insoluble solvents such as fluorocarbons. There are drawbacks. In addition, the method of recovering hydrophilic low-molecular-weight alcohols such as ethyl alcohol by passing through the activated carbon layer has the drawbacks that the adsorption efficiency for hydrophilic low-molecular-weight alcohols such as ethyl alcohol is low, the equipment is large, and the operating cost is high.

The current situation is that words have not been thought of at all.

Preferred examples include phenyl-modified silicones such as phenylmethyldiphenylpolysiloxane, tetramethyltetraphenyltrisiloxane, and pentaphenyltrimethyltrisiloxane; polyether-modified silicones such as phenylmethylsilicone, and particularly alcohol-based or fluorocarbon-based solvents. The above-mentioned phenyl-modified silicone, which has good compatibility with the silicone and has a high boiling point, can be preferably used. Furthermore, commercially available phenyl-modified silicones, polyether-modified silicones, etc. can also be used. The amount of the silicone oil to be used is not particularly limited, but in order to achieve low cost, for example, 0.00 parts by weight of the solvent to be adsorbed.
It is desirable to use it in a range of 0.01 to 10 parts by weight.

The gas containing the solvent may be brought into contact with the silicone oil using, for example, a known scrubber, packed column, wet wall, or the like. Next, the solvent adsorbed by the silicone oil in the contacting step is separated from the silicone oil by heat treatment, and can be easily recovered as a liquid. The heat treatment can be selected from various methods depending on the type of solvent, but it is preferably performed at a temperature 30 to 50° C. higher than the boiling point of the solvent in order to efficiently recover the solvent at low cost.

Further, although the above-mentioned specific silicone oil is very expensive for boat fishing, in the present invention, the solvent recovery efficiency is extremely good, and moreover, the solvent and silicone oil can be separated simply by heat treatment. Furthermore, since a distillation step is not required and the separated silicone oil can be reused, the solvent can be recovered at an extremely low cost compared to the conventional method. Therefore, for example, it is extremely useful for recovering alcohol and the like contained in the air in a warehouse for storing whiskey and the like.
