Evaporation generally occurs at low pressures; the lower boiling point of the solution facilitates an increase in the heat transfer temperature difference for evaporation； During pressure evaporation, the temperature of the resulting secondary vapor is high, and it can be used as heating vapor for the next stage.

Correct. Generally, evaporation occurs at low pressures; the lower boiling point of the solution facilitates an increase in the heat transfer temperature difference for evaporation； During pressure evaporation, the temperature of the resulting secondary vapor is high, and it can be used as heating vapor for the next stage.
