摘要: 中石油独山子1 000 kt/a乙烯装置自投产以来,稀释蒸汽过热器中压凝液线多次发生泄漏,通过利用化工计算对稀释蒸汽压力变动的偏差分析,发现造成稀释蒸汽过热器(E-3014)中压凝液线泄漏的原因是气液两相流和大流量超负荷冲蚀,提出了解决问题的优化建议和措施。

Abstract:

Since the 1,000 kt/a ethylene plant at PetroChina Dushanzi Petrochemical Company was started up, frequent leakage has been found in the medium pressure condensate line in DS superheater. This paper uses chemical calculation to analyze the deviation of DS pressure, finds out that the fundamental reasons for the frequent leakage of medium pressure condensate line in DS superheater E-3014 were the gas-liquid two-phase flow and the large flow overload erosion, and puts forward some optimization suggestions and effective measures.
