14. A method of flushing debris from a pressurized decoking valve body comprising the steps of:
-
opening a valve to allow entry of-fluid into a valve body to flush debris from the valve body with said fluid; allowing said fluid and any accumulated debris to drain from the valve body through an exit control valve; and allowing the fluid and accumulated debris to flow through the exit control valve into a condensate holding tank. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method of flushing debris from a pressurized de-coking valve body comprising the steps of shutting off a high pressure steam inlet valve;
-
opening a fluid inlet line shut off valve, allowing fluid to flow from the fluid inlet line into the valve body; flushing debris and residual materials from the valve body; allowing fluid flushed from the fluid inlet line through the valve body to drain through a condensation inlet line; allowing said fluid to flow from said condensation inlet line to a condensation holding tank; holding said fluid and debris for a period of time in said condensation holding tank; and allowing said fluid and debris in said condensation holding tank to flow into a coke pit.
