Reduction of metal stresses in delayed coking drums |
摘要 |
The metal stresses in a delayed coke drum are reduced by externally cooling the coke drum near the junction of the drum shell and the supporting skirt thereof during the quench step. This reduces the metal stresses at the area around the welds of the drum skirt. |
