    Recently we have problem in bottom head deheading.
    When we removed the bottom head, some tar-like material came out and solidified in the atmosphere.
     
    When we check the skin temperature of the coke drum during coking cycle,we find the temperature is only at 370C.
     
    We have heard that some coker raise heater COT for the last four hours of coking cycle.
     
    Could this practice solve our problem?
