Multiple effect evaporation

Multiple effect evaporation

Multiple effect evaporator is used for steam economy. 5.2 Multiple-Effect Evaporation . In any evaporation operation, the major process cost is the steam consumed. Therefore, methods of reducing steam consumption (or of increasing economy, defined as mass of vapour produced per unit mass of steam consumed) are very important. The most common of .  · M ultiple - effect evaporator. The 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 the heating medium for the ...

The multiple effect evaporation processes can optimise the energy efficiency of facilities through the recycling of vapour. Functioning. The vapour supplied during the first effect produces the vapour at a lower pressure. These vapours are then used in a second effect as a vapour heating steam. The number of effects vary and can go right up to 8. For engineering students.

Hence, the steam economy, which is kg vapor evaporated/kg steam used, is increased. This also holds approximately for more than three effects. However, the increased steam economy of a multiple-effect evaporator is gained at the expense of the original first cost of these evaporators. Evaporation 7 • If the vapor from one evaporator is fed into the steam chest of a second evaporator and the vapor from the second is sent to the condenser, the operation becomes double effect. • The heat in the original steam is reused in the second effect and the evaporation economy increased. • Also useful one the feed temp is very low ...

2) Evaporator Economy: Economy of the evaporator is another important parameter which decides the performance of evaporator. It may be defined as the amount of steam used and is expressed in terms of pounds of vapor produced per pound of steam supplied to the evaporator train.

Evaporator

called a single effect evaporator system and if more than one evaporator is used for the concentration of any solution, it is called a multiple effect evaporator system. In a multiple effect evaporator the vapour from one evaporator is fed into the steam chest of the other evaporator. A Falling Film Evaporator (FFE) is a vertical shell and tube heat exchanger with a vapor- liquid separator mounted at the bottom. The liquid to be concentrated is fed at the top of the heated tubes and distributed in such a way that it flows down on the inside surface of the tubes as a thin film.

Multiple effect Evaporator Working Principle. Multiple effect evaporator is the combination of several sets single effect evaporator. The characteristic is to heat the next effect evaporator by used steam produced from the front effect, so as to reduce energy consumption. Usually there is double effect evaporator, three effect evaporator or ... Evaporator used in Food Industries.

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. economy of multiple effect evaporator calculations 2017. Multiple Effect Evaporator - Swenson Technology 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.

The multiple-effect configuration combines two or more evaporator bodies to conserve steam, which is condensed in the first-effect heat exchanger only. Water evaporated in the first-effect vapor body is condensed in the second-effect heat exchanger, which provides energy for evaporation in the second-effect … Steam economy increases steadily in multiple-effect evaporators as the number of effects increases. Adding a thermocompressor to a three-effect system can approximately double the economy, but that pales in comparison to the potential steam economy of an evaporator with MVR — which is 5–10 times that of the three-effect evaporator.
