Does trace methanol in CO2 gas affect the conductivity of the desorbed waste liquid?
Thread Content
As the title suggests, low-temperature methanol is used for carbon removal; the CO2 gas contains trace amounts of methanol. Does this have an impact on the conductivity of the desorption waste fluid in urea production facilities, as well as on the analysis of NH3 content?
Looking forward to answers from professionals, hoping to win a prize
According to the information provided, Yinchuan Fertilizer Factory had formaldehyde in its process condensate, which affected the ammonia content and conductivity of the waste liquid sent out from the desorption tower. Someone from Haiyou in Yinchuan can provide more details on this; thank you!
The process condensate contains formaldehyde, which affects conductivity; there have been instances where formaldehyde entered closed discharge systems and ended up in the wastewater tank, causing the conductivity to rise
The effect of conductivity is minor; it mainly affects COD
