SYSTEM AND PROCESS FOR THE RECOVERY OF OIL FROM PYROLYSIS OF MATERIAL CONTAINING HIDROCARBONS

摘要

A system and process for the recovery of oil from the pyrolysis of material containing hydrocarbons such as shredded vehicle tires. The system utilizes a pair of sequentially positioned packed towers to recover at least 95% of the oil contained in the pyrolysis gases. The first packed tower operates above the dew point of the water vapor in the pyrolysis gases to insure that no water is condensed and obtain a primary oil fraction having oil with a high flash point of about 60 DEG C or greater and a primary vapor fraction containing additional oils, fuel gases and water vapor. The primary vapor fraction is fed to the second packed tower which operates below the dew point of the water vapor to condense the water and oil having a low flash point of 34 DEG C or below, and provide a secondary vapor fraction containing valuable fuel gases.
