Abstract

In quench towers and process water treatment section of steam generators, fouling decreases the performance, heat transfer rate, steam generation rate and increases rate of steam make-up for furnaces. In this study, Effective parameters like temperature, water contaminants, dissolved solids (e.g. Si, Fe,), PH, inhibitors and controlling chemical rates and dissolved oxygen which should be monitored for reducing  these problems, are surveyed. Installation of dissolved oxygen monitor in dilution steam generator inlet stream is recommended as a result of this study. As this device provides the possibility of oxygen measurement, optimization of oxygen generating chemicals injection rates could be achieved. The recommended analyzer has not been available in olefin plants so far.
