摘要: 针对加氢裂化装置高压空冷器管束易发生由腐蚀引起的泄漏事故,以某石化公司高压空冷器为例,
初步探讨了流体力学因素与高压空冷器管束冲刷腐蚀的关系。用失重法定量的研究了壁面剪切应力和湍流强度对
腐蚀的加速效果,并找出管束冲蚀破坏严重的位置。根据试验数据与计算流体力学(CFD)软件模拟结果,对高压空
冷器管束冲刷腐蚀速率进行了预测

Abstract: For the leakage of high pressure air cooler tubes caused by corrosion, relationship between hydrodynamic factors and erosion-corrosion of high pressure air cooler tubes in the hydrocracking unit of a petrochemical corporation was discussed. Accelerating effect of hydrodynamic factors such as turbulence intensity and shear stress acting on inner wall of air cooler tubes on corrosion were quantitatively investigated by a weight loss test method. The position badly destroyed by erosion-corrosion was found. Erosion-corrosion rate of high pressure air cooler tubes was predicted according to experimental data and CFD simulation results. 
