The corrosion failure of dilution steam generator in ethylene cracker was mainly caused by the electro-chemical corrosion from process water with dissolved CO_2,H_2S and Cl~-.
乙烯装置稀释蒸汽发生器腐蚀失效的主要原因是酸性介质CO_2,H_2S和Cl~-溶于工艺水后产生电化学腐蚀所致。
After modification,the problems of pH control stability and equipment corrosion were solved and the system has been operated stably,but the insufficient dilution steam generation and overhigh MP steam make-up brought a negative impact on further reducing the energy consumption of ethylene plant.
通过改造,虽解决了pH值稳定控制及设备腐蚀问题,目前系统总体运行稳定,但稀释蒸汽发生量不足、中压蒸汽补入量大,影响装置进一步降低能耗。
