Abstract
The present disclosure provides for processes including a coke catcher that may be emptied during normal operation or steam standby, thereby overcoming the deficiencies in the prior design as discussed above, the coke catchers and process flows disclosed herein protecting the secondary transfer line exchanger from foulant while not limiting the time between heater cold shutdowns. The designs consider the impact of decoking options, such as when decoking to a firebox as opposed to a decoking drum. Further, flow and cost considerations are addressed in various embodiments; for example, decoke valves are fairly expensive, and process flows disclosed herein may provide for relocation of the decoke valve to facilitate coke catcher operations while not adding an expensive valve to the overall operating flow scheme.
