Abstract:
Described herein are methods and mechanisms for laterally dispensing fluid to a coke drum in a predictable and maintainable manner that alleviates thermal stress. In one embodiment, the methods and mechanisms utilize a split piping system to dispense fluid through two or more inlets into a spool that is connected to a coke drum and a coke drum bottom deheader valve. A combination of block valves and clean out ports provides a more effective means to clean the lines and allows fluid to be laterally dispensed in a controllable and predictable manner. The fluid is preferably introduced to the spool in opposing directions toward a central vertical axis of the spool at equal but opposing angles ranging from minus thirty (−30) to thirty (30) degrees relative to a horizontal line laterally bisecting the spool. Alternatively, however, fluid can be introduced to the spool tangentially.
