evaporative duty

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。
