Problems in the urea evaporation process (aqueous solution)
Thread Content
1. What is the function of a steam trap in evaporation systems? 2. What is the purpose of installing a U-shaped bend between section 1 and section 2? 3. Is the function of a steam trap the same as that of an evaporative level tank?
1. The main function of a vaporizer-mounted hydrostatic separator is to cause the steam to condense, releasing the latent heat which is then absorbed by the urine, thereby saving as much steam as possible. 2. The main function of setting up the U-tube is to create a liquid seal between the first and second vapor phases, thereby maintaining their respective pressure levels. 3. The function of a steam trap should be the same as that of a level tank, but the level tank performs better than a steam trap.
