What are the calculation methods for multiple effect evaporators?

The calculations are done using material balances, heat balances, and the capacity equations q = UAAT for each effect. A convenient way to solve these equations is by trial and error. The basic steps to follow are given as follows for a triple – effect evaporators.

How to design a double effect evaporator?

The water or wastewater feed is pumped into the first effect and the partially concentrated solution is sent to the second effect. The heating steam is also sent through the first stage to the second one. This process is continuous and the ends on the last evaporation stage.

What is the process of a multiple effect evaporator?

In a multiple effect evaporator, water is boiled in a sequence of vessels, each of which is at a lower pressure than the last. As the boiling point of the water decreases with pressure, the vapor produced in one vessel can be used to heat the next vessel. Only the first vessel requires a source of external heat.

What is the investigation of multiple effect evaporator design?

A multiple effect evaporator is design to cut down the steam consumption by different operating strategies like feed, condensate and product flashing, vapor compression, vapor bleeding, feed and steam splitting and using an optimal feed flow sequence.
