Design & Analysis of Multiple effect Evaporator for Sugar Industry

A number of process industries, including pulp and paper, sugar, desalination, pharmaceuticals, dairy and food processing, etc., have evaporators as one of their most energy-intensive components. If the heat from the vapour is not used, a single effect evaporator might be energy inefficient. Using multiple-effect evaporators solves this problem. Because Vapour bleeding is implemented, Robert type evaporators are typically regarded as the preferred evaporator design in the cane sugar industry. The three-effect evaporator system model that will be created for this project has three effects. The model includes vapour bleeding as a way to cut back on the amount of steam used in the evaporator. Using waste heat while lowering steam consumption and heating power are the goals of multiple effect arrangements. This is accomplished by employing the vapour produced in the first stage as the second stage's heat source and the third stage's heat source. Condensate, feed and product flashing, vapour compression, and other energy-saving techniques are also available. Vapour bleeding improves the process's steam economy, but at the increased expense of the necessary heat exchangers. Along with designing this evaporator, we will analyse data to identify various stresses and develop a support system to minimise the evaporator's weight. .
