Evaporator design. It takes a large amount of energy to boil off water from a solution. This energy is often supplied as steam. To reduce the amount of steam needed, the evaporator is normally designed as a multiple-effect evaporator. Two or more effects operate at progressively lower vacuums and thus with progressively lower boiling points. In such an arrangement, the vapour produced in the ...
