摘要： A process for the production of alkylaromatic hydrocarbons uses a working fluid to reduce the costs of separating an unreacted aromatic feed substrate from aromatic hydrocarbon products. Unreacted aromatic substrate is combined with a light hydrocarbon, such as propane, to form a combined effluent stream. The combined effluent stream enters a flash separator where unreacted aromatic substrate is lifted overhead with the light hydrocarbon while heavier aromatic products are recovered below. The aromatic substrate and light hydrocarbon are easily separated in a simple separation zone. Lifting the aromatic substrate with the working fluid reduces the volume of aromatic substrate that remains with the aromatic product so that the more energy intensive separation of the aromatic substrate and aromatic product is performed on a reduced volume of material.
摘要翻译：用于生产烷基芳族烃的方法使用工作流体来降低将未反应的芳族原料基质与芳烃产物分离的成本。将未反应的芳族底物与轻质烃如丙烷混合以形成组合的流出物流。合并的流出物流进入快速分离器，其中未反应的芳族底物用轻质烃提升塔顶，而较重的芳族产物在下面被回收。芳香族基质和轻质烃容易在简单的分离区域分离。用工作流体提升芳香族底物可降低与芳香族产物残留的芳香底物的体积，从而在减少体积的材料上进行芳香族底物和芳香族产物的能量密度分离越多。
