If your processes use evaporation, what is the desired concentration? How is it controlled? How

is its operation affected by changes in steam pressure or temperature of the heat source?

1.         How is the level in the evaporator controlled? Is it ensured that all of the steam tube area is

used?

Q174  If a salt solution is being evaporated, is it known whether there is a phase diagram? If so, what is

the impact of operating changes?

1.       What can affect the heat transfer coefficient inside the evaporator?
