    • The invention is directed to a process wherein a feedstock or stream comprising steam cracker tar is passed to a vacuum pipestill. A deasphalted cut of tar is obtained as an overhead (or sidestream) and a heavy tar asphaltenic product is obtained as bottoms. In preferred embodiments, at least a portion of the bottoms product is sent to a partial oxidation unit (POX) wherein syn gas may be obtained as a product, and/or at least a portion of the bottoms product is used to produce a light product stream in a coker unit, such as coker naphtha and/or or coker gas oil. In another preferred embodiment at least a portion of the overheads product is added to refinery fuel oil pools and in yet another preferred embodiment at least a portion of the overheads product is mixed with locally combusted materials to lower soot make. Two or more of the aforementioned preferred embodiments may be combined.
    • 本发明涉及一种方法,其中将包含蒸汽裂解焦油的原料或料流送入真空管道。 作为塔顶(或侧流)获得焦油的脱沥青馏分,并且作为底部获得重质焦油沥青产物。 在优选的实施方案中,将底部产物的至少一部分送至部分氧化单元(POX),其中可以获得产物的合成气,和/或至少部分底部产物用于生产轻质产物 在焦化装置中,例如焦化石脑油和/或焦化瓦斯油。 在另一个优选的实施方案中,将至少一部分塔顶馏出产物加入到炼油厂燃料油池中,在另一个优选的实施方案中,塔顶产物的至少一部分与局部燃烧的材料混合以降低烟灰。 上述优选实施例中的两个或更多个可以组合。
