Why use Multi Effect Evaporators?

Multi Effect Evaporators

The term “evaporator” refers to process equipment used to extract liquid by vaporization. A single liquid, a liquid mixture, solutions or slurries, or any combination of these may be used as the feed material. To create vaporization, heat is delivered through some type of heat transfer surface. Evaporation systems are intended to concentrate feedstock into a heavy solution or slurry to reduce its volume for subsequent processing, use, or disposal.

Single effect evaporators and multiple effect evaporators are the two most common types of evaporators in the market. The benefits of multiple effect evaporators include their suitability for large-scale and continuous operation. When compared to a single effect, it is extremely cost-effective. Multiple effects are employed to reduce the amount of energy required to evaporate unwanted water content.

What is a multiple-effect evaporator/ MEE Evaporator?

A multiple-effect evaporator is a device that efficiently uses steam heat to evaporate water. Water is boiled in a series of containers, each at a lower pressure than the last, in a multiple-effect evaporator.

It is made up of several stages or “effects.” The feed water is heated by steam in tubes at each stage, commonly by spraying saline water on them. Some of the water evaporates, and the resulting steam flows into the tubes of the following stage (effect), heating and evaporating even more water.

MEE Evaporators are commonly used for product concentration and are currently being utilized to collect water from wastewater that may be reused for industrial processes, lowering the industry’s overall freshwater consumption and leading to zero liquid discharge and sustainable development.

What is Mechanical Vapor Recompression (MVR) Evaporator?

Mechanical Vapor Recompression (MVR) is a proven energy-saving evaporative concentration method that decreases evaporation energy usage by 90% or more. MVR Evaporator employs condensate energy to produce pure liquid distillate and concentrated product/waste.

Why MVR evaporator?

Many industrial applications use vapor recompression, including those in the dairy, saline, and distillery sectors. Mechanical vapor recompression, in particular, is frequently used in industrial evaporators for solids concentration in distillation facilities. The goal is to transfer waste heat from a wasted vapor stream by increasing its pressure and reusing it to collect its usable energy.

To do this, the vapor produced by evaporator steam is compressed, causing its temperature and pressure to rise. As the pressure rises, so does the saturation temperature. This temperature rise results in a temperature differential between the exhaust vapor and the working fluid. The temperature difference allows heat to be transferred between the two fluid streams through a heat exchanger.

Energy Savings Using MVR Evaporation System

The major advantage of the MVR Evaporation System is that it saves a lot of energy. Unlike the alternative thermal vapor compression, mechanical vapor compression does not require an extra steam supply. Because there is no fluid mixing, all of the available vapor may be compressed for energy recovery.

This approach is appropriate for systems with a minimum temperature differential, such as many evaporation plants; in these situations, large heat transfer area heat exchangers can be used to maximize energy recovery.

Mechanical vapor recompression has a large energy-saving potential when compared to the energy required to create fresh steam. In reality, mechanical vapor recompression techniques are commonly used in multi-effect evaporators. Mechanical vapor recompression may be highly cost-effective even in multi effect evaporator systems where the vapor from the last effect is condensed in the first-effect heat exchanger.

Mechanical Vapor Recompression (MVR) evaporators are becoming more popular as energy costs rise. MVR evaporator technology has the potential to save a large amount of energy. CentPro evaporators are designed to operate with extremely little specific energy while producing clean condensate to reduce fresh water consumption.
