Multiple-effect evaporator Wikipedia

A multiple-effect evaporator, as defined in chemical engineering, is an apparatus for efficiently using the heat from steamto evaporate water. In a multiple-effect evaporator, water is boiled in a sequence of vessels, each held at a lower pressure than the last. Because the boiling temperature of water decreases as pressure decreases, the vapor boiled off in one vessel can be used to heat the next, and only the first vessel (at the highest pressure) requires an external source of heat. While in theory, evaporators may b

Multiple-Effect vacuum evaporators Condorchem Envitech

A multi-effect vacuum evaporator consists of a set of interconnected evaporators where the first effect is the first evaporator, and so on. Using a multiple effect evaporator, the operation is based on the steam produced in one effect being used as the heat source for the following effect.

Multiple Effect Evaporators Rosenblad

Multiple-Effect Evaporators. Multiple-effect evaporators maximize steam economy as vapor generated from one effect is used to drive another. This type of multiple-effect system is perfect for continuous feed applications, as fluids are progressively reduced in each effect

Multiple-effect evaporation plants

In case of multiple-effect evaporation plants, the exhaust vapors from the product are used to heat the downstream-arranged evaporation effect so that the steam consumption will be reduced accordingly. Considering the heat balance of a single-effect evaporator the heat content (enthalpy) of the evaporated vapor is approximately equal to the

DE-9: Lesson 5. BASIC CONCEPTS OF MULTIPLE EFFECT

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.

How do multiple effect evaporators work?

Jan 27, 2020 A multiple-effect evaporator uses the water vapor from one effect as the heating medium for the next effect, which operates at a lower boiling point. The latent heat in water vapor can also be reused by thermally or mechanically compressing the vapor to
