Investigation on the use of steam in urea hydrolysis towers
Thread Content
Dear sea friends, what process do you use for urea hydrolysis? What is the pressure of the steam used for hydrolysis? Saturated or superheated?
It doesn’t matter whether it’s superheated steam or saturated steam, right?
We use superheated steam, with a pressure of 2.2 MPA and a temperature of 310 degrees
2.5MPA 230 degrees is also considered superheated steam
The temperature corresponding to 2.2 MPA saturated steam is 222°C, which is a high degree of superheating.
It was reduced from 4.1 MPa to 2.2 MPa, and the temperature was also lowered from 382 degrees using cooling water. Both temperature and pressure are adjustable
We use exhaust gas from C02 compressor turbines; it is superheated steam with a pressure of 2.2 MPA and a temperature of around 310 degrees
