Multiple Effect Evaporator - Swenson TechnologyThe driving force is the pressure drop from the first to the last effect. For the same overall pressure differential and process conditions, the evaporator with more effects will require less steam. The evaporation in each effect will be approximately 0.7 to 0.9 pounds for each pound of steam condensed in the first-effect heat exchanger.

Evaporator problem can affect the functioning of an HVAC system. Experts on JustAnswer have answered a wide variety of questions on evaporator problems.
RMP Lecture Notes - Christian Brothers UniversityIn a single-effect evaporator, steam provides energy for vaporization and the vapor product is condensed and removed from the system. In a double-effect evaporator, the vapor product off the first effect is used to provide energy for a second vaporization unit. Triple- effect evaporator problems are familiar to generations of engineering ...
Solved: A Double-effect Evaporator (two Evaporators In Ser ...A double-effect evaporator (two evaporators in series) is used to produce fresh water from seawater. containing 3.5 wt% dissolved salts. A flowchart for the process is shown here. Seawater enters the first effect at 300K at a rate of 5000 kg/h, and saturated steam at 4.00 bar. absolute is fed into a tube bundle in the first effect.
COMPARISION OF SINGLE AND MULTIPLE EFFECT EVAPORATOR - BloggerThe single effect evaporator uses rather more than 1 kg of steam to evaporate 1 kg of water. The latent heat of the vapor leaving in single effect evaporator is not used but is discarded. Much of this latent heat, however, can be recovered and reused by employing a multiple - effect evaporator, that is, vapor from one effect serves as heating ...

RMP Lecture Notes - Christian Brothers UniversityTypically, multiple effect evaporator calculations require an iterative solution procedure because so many of the required properties, etc., depend on unknown intermediate temperatures. Fortunately, the overall approach is basically the same for the majority of problems, requiring only minor adjustments to compensate for problem quirks.

Evaporator Handbook - APV Hemisancontrast, the falling film evaporator does not have a driving force limitation—permitting a greater number of evaporator effects to be used within the same overall operating limits. For example, if steam is available at 220°F (104°C), then the last effect boiling temperature is 120°F (49°C); the total available ΔT is equal to 100°F (55°C).
