Ammonia evaporation efficiency in the ammonia evaporation tower
Thread Content
Recently, the ammonia evaporation process in the ammonia evaporation tower has not been effective; the temperatures at the bottom and top of the tower can rise, but the temperature in the separator does not increase – it stays around 80 degrees. Even when all water flow is stopped, the temperature remains at 80 degrees, and the wastewater at the bottom of the tower is in gaseous form. I’m not sure what to do now.
Is there an internal leak in the reducer? Check it first before making a judgment
I wondered about it too, but when the water is turned up high there’s no sign of leakage; I wondered if maybe the tray is blocked
After the tray gets clogged, the pressure at the bottom of the tower is high; therefore you need to check it again
The temperature at the bottom of the tower is currently 112 degrees; there is no pressure at that level. The temperature at the top of the tower has just reached 100 degrees, while the pressure there is around 50 KPa. Ammonia nitrogen levels have decreased now, but the steam flow rate is over 70%, with a steam pressure of around 0.3. Additionally, the temperature of the ammonia feed entering the tower is also above 98 degrees. I think this isn’t normal. The amount of ammonia water fed in is only 20 cubic meters per hour, and the temperature in the fractionator is also around 100 degrees
Can you confirm that all the instruments you are using are accurate?
The temperature at the bottom of the tower must not rise any further, otherwise the tar will turn into a solid inside the tower
The gauge at the bottom of the tower is definitely inaccurate. The pressure gauge at the bottom of the tower is usually above the liquid phase, while the temperature gauge is below the liquid phase. The pressure at the top of the tower is 50 ka, while there’s no pressure at the bottom of the tower; everything is being sucked in@@
1. The pressure gauge at the bottom of the tower needs to be calibrated. 2. There is a blockage, possibly in the concentrated ammonia pipeline or similar.
