摘要： A quench nozzle design introduces quench oil tangentially into the quench tube which cools the hot gaseous pyrolysis products coming out of the hot radiant tubes in a pyrolysis furnace (in ethylene manufacture). Besides cooling the hot gases, the quench oil introduced into the quench tube by this nozzle design keeps the wall of the quench tube wetted, which is necessary to prevent coke deposition on the quench tube. The nozzle has one quench oil entry, which eliminates the need for any restriction orifice required to evenly distribute quench oil flows that would otherwise be required with several nozzle entries. Also, the one-nozzle oil introduction has a larger diameter than that required where more than one nozzle is employed in this service. The replacement of multiple nozzles with a single larger diameter nozzle eliminates plugging problems caused by coke solids or, coke solid precursors, present in the quench oil.
摘要翻译：淬火喷嘴设计将淬火油切向地引入淬火管中，淬火管冷却热解炉（在乙烯制造中）从热辐射管出来的热气体热解产物。除了冷却热气体之外，通过这种喷嘴设计引入淬火管的骤冷油也可以使淬火管的壁湿润，这是防止焦化沉积在淬火管上所必需的。喷嘴具有一个骤冷油入口，这样就不需要均匀分配淬火油流所需的任何限制孔，否则这些流量将是多个喷嘴入口所必需的。此外，单喷嘴油引入具有比在该服务中使用多于一个喷嘴所需的直径更大的直径。使用单个较大直径的喷嘴替换多个喷嘴消除了存在于骤冷油中的焦炭固体或焦炭固体前体引起的堵塞问题。

摘要： A centrifugal vapor/liquid separator separates the vapor and liquid in a flash of hydrocarbon and steam mixture, such that only the vapor stream is fed and processed further downstream. The design of the separator ensures that all partially wetted surfaces in the separator, except at the vapor outlet pipe, are well-wetted and washed by the non-vaporized liquid portion of the feed or by injection of external liquid thus ensuring that no coke deposition occurs inside the separator. The flash temperature in the separator therefore can be increased beyond the typical limit thus achieving a deeper cut into the feed and recovering a larger fraction of the feed as vapor for further downstream processing.
摘要翻译：离心蒸汽/液体分离器将蒸气和液体分离成一系列烃和蒸气混合物，使得仅蒸汽流进一步下游进料和处理。分离器的设计确保除蒸气出口管外的分离器中的所有部分润湿的表面均被良好润湿并且被进料的非汽化液体部分或通过注射外部液体洗涤，从而确保没有焦炭沉积发生在分离器内。因此，分离器中的闪蒸温度可以增加超过典型的极限，从而实现对进料的更深的切割并且作为蒸气回收更大部分的进料以进一步下游加工。
