The basis of vacuum evaporation - Environmental engineering

Evaporation is an operation that is controlled by the rate of heat transfer, and the evaporation rate depends on the following factors: 1. Temperature difference between the heating agent and the liquid to be evaporated. The boiling temperature of the liquid to be evaporated increases as it becomes more concentrated. However, as the process is .
