Vacuum-evaporated atmospheric leg and indirect condenser
Thread Content
In vacuum evaporation, the secondary steam generated in the final stage is condensed either by direct spraying using an atmospheric leg or through indirect condensation using an indirect condenser. Could any of you share the advantages and disadvantages of these two methods?
The atmospheric condenser provides direct cooling, facilitating vacuum creation and ensuring a high level of vacuum. Surface condensers provide indirect cooling, and it seems to require higher standards for vacuum pumps
