处理烃基重质残留物的方法
摘要：
处理烃基重质残留物(1)，特别是处理具有高沥青质含量的沥青残留物，的方法，其包括下面的操作：A)将待处理的重质残留物置于325－500℃的温度；B)在压力等于或者低于大约0.1bara和温度等于或者低于450℃的环境中，使待处理的重质残留物经历基本上绝热膨胀，来从该待处理的重质残留物中分离第一较低挥发性馏分(17)，该第一较低挥发性馏分在大气压时下沸点等于或者高于540℃，并且它的固体和/或无水残留物主要包含不溶于戊烷的沥青质和/或不溶于四氢呋喃的其他残留物。它允许更有效的冲洗，以及在极其简单的设备中启动所述方法，而无需离心分离。
摘要（英）：

A process for treating a hydrocarbon-based heavy residue (1), in particular bituminous residues with a high asphaltene content, comprises the following operations : A) bringing the heavy residue to be treated to a temperature within the range of 325-500 DEG C; B) subjecting the heavy residue to be treated to a substantially adiabatic expansion in an environment at a pressure equal to or lower than about 0.1 bara, and at a temperature equal to or lower than 450 DEG C, so as to separate, from the heavy residue to be treated, a first less volatile fraction (17) having a boiling point at atmospheric pressure equal to or higher than 540 DEG C and whose solid and/or anhydrous residue prevalently contains asphaltenes insoluble in pentane and/or other residues insoluble in tetrahydrofuran. It allows a more effective flushing, and also to actuate the process in an extremely simple plant and without centrifugations.
