摘要
旨在探讨催化裂化装置中消白烟设施的结垢问题.通过对带有烟气消白烟设施的催化裂化装置的现场数据分析,详细阐述了结垢的成因、影响因素以及有效的解决策略.分析发现,烟气线速、消白烟设施的换热温度是影响结垢的关键因素.通过优化操作参数,可以显著降低结垢速率,提高装置运行的长周期和稳定性.
Abstract
The purpose of this study is to discuss the scaling problem of white smoke removal facilities in catalytic cracking units.Based on the analysis of the field data of the catalytic cracking unit with flue gas whitening facilities,the causes of scaling,influencing factors and effective solutions are described in detail.It is found that the flue gas line speed and the heat transfer temperature of the white smoke removal facility are the key factors affecting the scale formation.By optimizing operation parameters,the scaling rate can be significantly reduced,and the long cycle and stability of the device can be improved.
