<p><P>PROBLEM TO BE SOLVED: To provide a liquefaction apparatus with little adherence of an impurity component, wherein the apparatus can be easily cleaned, and to provide a liquefaction method. <P>SOLUTION: A liquefaction apparatus 40 includes: a heating bath 41 into which a plastic 48 is put; a heat source 41c for heating the plastic 48 in the heating bath 41; a cooling separating bath 42 provided above the heating bath 41; a steam pipe 47 for guiding steam generated in the heating bath 41 to the cooling separating bath 42; and a separator liquid tank 43. The cooling separating bath 42 cools steam generated from the plastic 48 to change the steam into a liquid and separates the liquid into an oil 55 and a deposit 56 by using a difference in specific weight. The separator liquid tank 43 stores a separator liquid 57 having a specific weight between the oil 55 and the deposit 56, and supplies the separator liquid 57 to the cooling separating bath 42. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
