Reasons for the high silicate content in urea condensate in the carbon dioxide gas method
Thread Content
Could that expert explain the reason for the high level of silicate in the steam condensate produced during the production of urea using the carbon dioxide method?
It’s probably because the silica content in the steam is too high. It could be a problem with the boiler or the pipelines, or it might be due to other substances leaking in. Alternatively, the quality of the water used to feed the boiler that generates steam may not be good enough. Once this exceeds the limit, it becomes quite troublesome. Actions to take: Increase boiler blowdown, eliminate leakage points, replenish qualified deionized water for drainage replacement, and check the quality of the condensate.
It is also possible that the steam condenser in the urea zone is leaking, allowing circulating water to enter
Are there any other phenomena? What about sodium ions?
The sodium ion level is also high; we have checked several devices and already removed the flash steam
