Thermal cracking of retort oil

The thermal cracking of retort oil vapors in an elongated reactor is improved by passing the effluent oil vapors and gases from a retort to a thermal cracking unit before the temperature of the retort effluent falls below 680 DEG F. This encourages the more desirable cracking reactions, increases th...

More Information
Summary:The thermal cracking of retort oil vapors in an elongated reactor is improved by passing the effluent oil vapors and gases from a retort to a thermal cracking unit before the temperature of the retort effluent falls below 680 DEG F. This encourages the more desirable cracking reactions, increases the thermal efficiency of the process, and avoids preheater coking.
