Temperature of the secondary steam in MVR low-temperature evaporation
Thread Content
Seeking help: I’m a complete beginner. What is the relationship between the temperature of the secondary steam in MVR low-temperature evaporation and the temperature of the liquid phase in the separation chamber? For example, in the case of a saturated NaCl solution, if the liquid phase temperature is 85°C and the boiling point elevation is 8°C, what should be the temperature of the gas phase at this time? :'(
①The secondary steam temperature is the saturated steam temperature corresponding to the pressure in the separator at that time; for example, if the separator pressure is 101 kp, then the temperature of the gas phase is 100℃； ②The liquid phase temperature refers to the temperature in the solvent that is usually higher than the evaporation temperature due to the presence of solutes; this increase in temperature is commonly known as boiling point elevation, that is, liquid phase temperature minus secondary steam temperature (at the compressor inlet)
