Abstract
本发明涉及一种用于控制进入转化工艺的入口温度Ti的方法，所述方法包括以下步骤：提供用于转化工艺的进料；在第一温度控制步骤中，在废热锅炉中调节进料的温度；在第二温度控制步骤中，以获得进入转化工艺的期望的入口温度的量和/或温度向所述废热锅炉下游的进料中注入水流。
Description
废热锅炉(WHB)的尺寸对许多工艺设备的成本以及维护都有显著影响。
在本发明的第一方面中，提供了一种方法和设备，其允许使用具有比通常工艺设备中所采用的体积更小的体积的WHB。
在本发明的第二方面中，提供了一种方法和设备，其中可以降低对于处理工艺冷凝物的容量要求。
这些和其他优点通过用于控制进入转化器的入口温度(Ti)的方法来提供，所述方法包括以下步骤：
-提供用于转化工艺的进料；
-在第一温度控制步骤中，在废热锅炉中通过间接热交换来调节进料的温度；
-在第二温度控制步骤中，向废热锅炉下游的进料中注入水流。
由于以两个步骤控制进料的温度，所以与其中仅使用废热锅炉来将进料的温度降低至期望的入口温度的已知工艺相比，对于第一温度控制步骤中的废热锅炉的要求是不同的。当在第二温度控制步骤中进一步调节温度时，废热锅炉可以被设计成具有更高的出口温度，这具有使锅炉中的传热面积减小的优点。
如果水流是来自其中实施了该方法的设备的一个或多个工艺的锅炉给水和/或工艺冷凝物，则可以使用设备中现有的水源。此外，当使用工艺冷凝物时，由于在第二温度控制步骤中引入了工艺冷凝物，因此可以显著减少需要送至废水处理的来自下游工艺的工艺冷凝物的量。
在许多有利的实施方案中，转化是高温变换转化。
进料可以例如是来自二级重整器或自热重整器(ATR)或例如管状重整器的流出物。
本发明的方法可以例如应用于氨设备、甲醇设备或包括重整器的另一种类型的化学设备。
通过在第二温度控制步骤中引入到进料中之前将水流的温度调节到适于冷却进料流的温度，可以通过在第二温度控制步骤中所添加的水的量和/或通过所添加的水的温度来调节第二温度控制步骤中进料的温度。
例如，所添加的水的温度为0-200℃。
优选地，在位于转换步骤上游的废热锅炉下游测量用于转化工艺的进料的温度，以确保使进料达到所期望的入口温度。如果进料的温度不同于优选的入口温度，则可以调节在第二温度控制步骤中添加至进料中的水的量和/或温度，以实现期望的入口温度。
优选地，第一温度控制步骤之后的进料的温度高于期望的入口温度Ti，由此第二温度控制步骤可以用于微调进料的温度，以实现期望的入口温度。此外，当第一温度控制步骤之后的进料温度高于期望的入口温度Ti时，不需要用于提高进料温度的步骤。
设备的负载条件以及由此的转化步骤中的条件可能影响给定的反应器/转化器的最佳入口温度。这意味着，用于各种实施方案中的转化工艺的进料的入口温度Ti可以基于设备负载条件来调节。
由于通过在第二温度控制步骤中添加水来提高进料流的蒸汽/碳(S/C)比例，本发明的方法可以有利地应用于在第二温度控制点上游的需要或受益于降低的S/C因子的设备或工艺。
本发明另外提供了一种设备，其包括重整器、第一温度控制点、第二温度控制点、诸如高温转化器的反应器/转化器、一个或多个温度测量装置，其中第一温度控制点包括废热锅炉且第二温度控制点包括用于将水添加至用于转化器的进料流的装置。优选地，该设备被布置以用于本文所述的方法。设备中的进料流可以是来自二级重整器、或者例如ATR或管状重整器的流出物。
图1示出了示例性的设备部分1并且阐述了根据本发明的方法。
该设备包含进料流2，其经过第一温度控制步骤3和第二温度控制步骤4，然后进料至转化步骤5。在本实施例中，进料流是来自二级重整器6的流出物，并且转化5是高温转化。
可以通过阀8来控制水7向第二温度控制步骤中的注入。阀6可以接收例如来自TIC9的一个或多个温度传感器/受其控制。
在第一温度控制步骤3中，废热锅炉(WHB)可以例如是120B WHB，其中在第二温度控制步骤中，WHB温度控制至少部分地被经由注入水进行的温度控制所交换。
在本实施例中，来自重整步骤的流出物(进料)的温度为约1050℃。在第一温度控制点之后，温度为大约425℃，并且在第二温度控制点之后，进料达到期望的入口温度Ti＝360℃。
来自转化步骤的流出物可以例如被送至第二锅炉并用于任意的进一步处理。
