<p><P>PROBLEM TO BE SOLVED: To make it possible to detect the liquid level in a pyrolysis tank by a simple means in pyrolyzing a plastic solution in the pyrolysis tank. <P>SOLUTION: The liquid level in a pyrolysis tank 2 during pyrolysis is detected by making communication between the pyrolysis tank 2 and an auxiliary tank 8 through a passageway 7, continuously feeding a plastic solution into the pyrolysis tank 2 through the auxiliary tank 8, pyrolyzing the plastic, and detecting the liquid level in the auxiliary tank 8. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
