摘要：

急冷水塔作为乙烷裂解制乙烯装置的核心设备，主要作用为进一步降低裂解气的温度至近常温，并实现水、重芳烃、重焦油的分离。急冷水塔填料压差持续上涨不仅造成裂解气压缩机能耗增加，且存在塔内件坍塌、塔内液泛造成压缩机联锁停机的风险，严重制约乙烯装置的长周期运行。文中针对急冷水塔填料结垢、压差上涨的问题，采用下层填料洗油在线冲洗的方法将压差由8.0 kPa降低至3.6 kPa，并分析填料结垢的原因，为急冷水塔防结垢提出合理化措施。

Abstract:

As the core equipment of ethylene plant, quench water tower is mainly used to further reduce the temperature of cracking gas to near ambient temperature and achieve the separation of water, heavy aromatic hydrocarbons, and heavy tar. The continuous increase in packing pressure difference in quench water tower not only increases the energy consumption of cracking gas compressor, but also poses risks of tower internal collapse and tower flooding, which can lead to compressor interlock shutdown, severely restricting the long-term operation of ethylene plant. This article focuses on the problems of packing scaling and increased pressure difference in quench water tower. Online flushing is adopted for the lower packing to reduce the pressure difference from 8.0 kPa to 3.6 kPa. Reasons for packing scaling are analyzed, and reasonable measures are proposed to prevent the scaling in quench water tower.

Key words: ethane cracking, quench water tower, structured packing; scaling
