    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.

    Abstract translation: 本公开提供了包括在正常操作或蒸汽待机期间可能被清空的焦炭捕集器的过程,从而克服了如上所述的现有设计中的缺陷,本文公开的焦炭捕集器和工艺流程保护二次转移线交换器免受污染物 不限制加热器冷关闭之间的时间。 这些设计考虑了除焦选项的影响,例如当用焦炉除焦时与焦炭除焦鼓相比。 此外,流程和成本考虑在各种实施例中得到解决; 例如,分流阀相当昂贵,并且本文公开的工艺流程可提供分流阀的重新定位以促进焦炭捕集器操作,同时不向整个操作流程方案添加昂贵的阀。
