Abstract
Methods and compositions are provided which decrease the risk and spillage associated with discharging coke from a coking vessel. The risk to workers is decreased by eliminating the need for workers to be near the coking vessel while the head is being removed. The spillage is decreased by modifying the effective diameter of the coke chute inlet in a manner which allows it to catch any materials discharged from the coking vessel both during and after the opening of the bottom head. The process can enhance drum draining and further eliminate the need for process piping to facilitate the draining of water from the coking vessel.
