Crystallization temperature at various points of carbon dioxide stripping
Thread Content
1. Crystallization temperature of the liquid from the high-pressure washer 2. Crystallization temperature of the liquid from the low-pressure methamine condenser 3. Crystallization temperature of the liquid from the hydrolysis reflux condenser 4. Crystallization temperature of the liquid in the evaporation U-tube
It’s an approximate value; I can’t remember the exact one. Under normal operating conditions: 1. The crystallization temperature of the liquid exiting the high-pressure washer is 120°C. 2. The crystallization temperature of the liquid exiting the low-pressure methamine condenser is 55°C. 3. The crystallization temperature in the hydrolysis reflux condenser is 45°C. 4. The crystallization temperature in the evaporation U-tube is 123°C℃
It seems that the first and fourth ones aren’t that high

The design temperature of our factory is 105 68 50 119
