Conference: RefComm 2021

Automated bottom unheading devices have become standard equipment in most coke drums and has made operation much safer that it used to be. However, the associated change from a central inlet feed to a single side inlet feed resulted in asymmetric flow patterns that appear to have caused adverse side effects such as increased tilting, blowouts, and cone damage. This presentation introduces a new patented design that combines the benefits of an automated unheading device with a centralized feed inlet that promotes symmetric flow patterns in coke beds.
