摘要
裂解过程中产生的表面活性组分和加入的化学添加剂能导致油水界面张力降低,使得从工艺水中分离裂解汽油变得更难。工艺水中裂解汽油含量过高会导致工艺水汽提和稀释蒸汽发生系统结垢加剧,裂解汽油损失,污水处理费用上升,停车时间延长和运行成本增高。文中详细介绍了高效液/液聚结器在Naphtachimie装置4a多的使用情况。该技术分离效果显著,每年可节约操作费用约30万美元。
High concentration py - gas in process water will lead to severe fouling of stripper and DSS resulting in the loss of py - gas, increasing of waste water treatment cost and operation cost. The paper introduces the application of high efficient liquid - liquid coalescer. Improved separation efficiency has achieved significant operation savings about 300 thousand dollars per year.
