Single effect evaporation: When a single evaporator is used,the vapor from the boiling liquid is condensed and discarded. This is called single effect evaporation. It is simple but utilizes steam ineffectively. To evaporate 1 kg of water from the solution we require 1-1.3 kg of steam.

Sep 05, 2015· Description of a single effect evaporator used in concentrating liquid foods.
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. For the same evaporation rate, a five-effect evaporator will require about 25% of the steam required for a single-effect evaporator. In actual practice, the steam economy can vary widely because of .
An early step in heat exchanger design is finding the heat transfer surface area needed for a specified heat transfer rate, estimated overall heat transfer coefficient, and calculated log mean temperature difference. The needed heat transfer surface area is calculated from the basic heat exchanger design equation: Q = U A (log mean temperature difference).

The typical evaporator is made up of three functional sections: the heat exchanger, the evaporating section, where the liquid boils and evaporates, and the separator in which the vapour leaves the liquid and passes off to the condenser or to other equipment. In many evaporators, all three sections are contained in a single vertical cylinder.

Heat Exchangers 73 individual thermal resistances of the system. Combining each of these resistances in series gives: 1 UA = 1 (ηohA)i 1 Skw 1 (ηohA)o (5.7) where η0 is the surface eﬃciency of inner and outer surfaces, h is the heat transfer coeﬃcients for the inner and outer surfaces, and S …
This rate of heat transfer is the same as that obtained with a single effect operating between the same ultimate temperature levels. Thus, multiple-effect evaporation using n effects increases the steam economy but decreases the heat flux per effect by a factor of about 1/n relative to single-effect operation under the same terminal conditions.
Evaporators - A Design Philosophy That Assures Optimum Performance. Every Samsco Evaporator is designed to continuously concentrate water-based chemicals under harsh, ever-changing conditions. This demands uncompromising attention to system design, materials of construction, component selection, and safe process control logic.

The key factor in determining the economy of an evaporator is the number of effects. The economy of a single effect evaporator is always less than 1.0. Multiple effect evaporators have higher economy but lower capacity than single effect. The thermal condition of the evaporator feed has an important impact on economy and performance.
