Description

提高石油焦的干磨效率的方法
本发明涉及一种提高石油焦的干磨效率的方法，包括将添加剂添加至石油焦中并将石油焦连同添加剂一起干磨。
石油焦炭(石油焦)是来自炼油厂焦化装置单元或其它裂化工艺的含碳固体。其是来自炼油厂的副产物并且主要由碳构成。燃料级的石油焦还包含高水平的硫。多年来对对石油焦有相当多的关注，因为其通常比煤便宜并且具有非常高的热值。存在三种类型的石油焦，其取决于生产工艺而被生产。存在延迟、流化和灵活焦化，延迟焦化构成超过总产量的90％。所有这三种类型的石油焦具有比煤更高的热值并包含更少的挥发性物质和灰分。
石油焦的主要用途是作为水泥生产、发电和钢铁生产的能量来源。在水泥工业中对于有效利用石油焦作为燃料有许多限制。这些限制之一是石油焦的硬度，其硬度大于煤并因此增加了研磨系统的能量消耗。由于其低含量的挥发性物质，石油焦具有差的点燃和燃尽特性。因此，必须将石油焦研磨至比常规燃料高得多的细度以使其可用作水泥窑或煅烧炉中的燃料。然而，石油焦难以研磨，这主要是由于其高碳含量，该高碳含量具有润滑作用，使得石油焦显示出更小的通过研磨系统中的摩擦和磨损而粉碎的趋势。
与在水泥窑或煅烧炉中燃烧石油焦相关的进一步问题是其高硫含量。由于石油焦燃烧所需的高水平的过量空气，SO2排放相对高。在熔渣工艺的过程中，SO2被吸收到水泥熟料中作为硫酸盐。由于高硫含量，在水泥窑中燃烧石油焦期间还可出现操作问题，例如窑入口处和预热器以及预分解炉旋风分离器中的堵塞。
US4162044公开了一种使用研磨助剂在液体介质中研磨煤或矿石以增加研磨效率的方法，所述研磨助剂包括来源于聚丙烯酸的阴离子聚合电解质。
US4136830公开了一种研磨煤或包含有价金属的矿石的方法，包括在液体介质中并采用研磨助剂进行所述研磨，以增加研磨效率，所述研磨助剂包括苯乙烯与马来酸酐的共聚物或共聚物的盐。
因此，本发明的一个目的是提高石油焦的干磨效率。特别地，本发明目的在于减少将石油焦研磨至给定细度的能量消耗和/或采用相同的能量消耗而提高研磨细度。
为了解决此目标，本发明的方法包括将添加剂添加至石油焦中并将石油焦连同添加剂一起干磨，其中至少一种有机添加剂和至少一种无机添加剂的组合被用作所述添加剂。因此，本发明使用有机研磨助剂和无机添加剂的组合和协同效应。有机研磨助剂用于防止在研磨过程期间或之后经研磨的石油焦颗粒再附聚。大多数有机研磨助剂，例如链烷醇胺，由极性有机化合物组成，所述极性有机化合物排列其偶极，以使新形成的颗粒表面上的电荷饱和，减少再附聚。
优选地，至少一种有机添加剂选自链烷醇胺如三丙醇胺、多元醇如二乙二醇、聚酰胺、聚酯、聚醚、聚羧酸酯、聚羧酸醚、聚氧化烯烷基碳酸钠、胺的盐、多元醇的盐及其组合。
优选地，至少一种无机添加剂选自石灰岩、白云质石灰岩、粉煤灰、炉渣、粘土、红土、铝土、铁矿石、砂岩及其组合。无机添加剂为研磨方法提供了磨损效应，从而提高研磨效率。
在本发明的一个特别优选实施方案中，无机添加剂包括石灰岩。石灰岩具有结合石油焦在燃烧期间(火焰原位)的硫含量的效果，使得防止SO2被吸收入水泥熟料中。
优选地，无机添加剂包含选自石灰岩、白云质石灰岩及其组合的第一组分，以及选自石灰岩、粉煤灰、炉渣、粘土、红土、铝土、铁矿石、砂岩及其组合的第二组分。
优选地，将添加剂以石油焦的0.51-10wt-％的量添加至石油焦中。因此，添加的有机和无机添加剂的总重量是0.51-10wt-％。
添加的添加剂的最大部分由无机添加剂组成。优选地，将一种或多种无机添加剂以石油焦的0.5％-9.99wt-％，特别地6-8wt-％的量添加至石油焦中。
优选将一种或多种有机添加剂以石油焦的0.01％-0.1wt-％的量添加至石油焦中。
本发明可用于研磨单独的石油焦或研磨与煤组合的石油焦。
原则上，任何类型的磨机设计可用于本发明的上下文中用于研磨方法。最优选地，可使用立式辊磨机，其有利于石油焦研磨，因为其能在较低的能量需求下将石油焦研磨至更细的尺寸。然而，也可使用球磨机和E-磨机系统。
