The performance of multiple effect evaporators is measured in terms of its capacity and economy. The capacity of the evaporator is defined as the number of kilograms of water vaporized per hour. Its economy is the number of kilograms of water vaporized from all the effects per kilogram of steam used. For a single effect … Read more

As we know, an evaporator is a heat exchanger where in liquid is boiled to produce vapour and simultaneously it generates a low-pressure steam. This steam is further used as the heating medium for another following evaporator. Thus the second evaporator is a low-pressure boiler. The utilization of steam in first evaporator is called as … Read more

A climbing film vertical long tube evaporator is a type of evaporator that is essentially a shell and tube heat exchanger. Thus, it is also known as a rising film evaporator. This evaporator is superior to the falling film evaporator as the upstream film movement causes some particles to remain in the feed stream. The … Read more

A horizontal tube evaporator is frequently found to be the most adaptable choice for simple evaporation wherein liquids are not viscous and do not deposit scale or salt on the surface. Principle of Horizontal Tube Evaporator The principle mechanism involved in this type of evaporator is that steam is passed through tubes arranged horizontally. Heating … Read more

The evaporating pan is also called a steam jacketed kettle. In this type of evaporator, the movement of the liquid to be evaporated is due to the convection currents set-up by the heating process. It is a type of natural circulation evaporator. It consists of a hemispherical pan surrounded by a steam jacket. The hemispherical … Read more

The Difference Between evaporation and other heat processes like Vaporization, Distillation, Drying, and Sublimation… Difference between Vaporization and Evaporation Vaporization (Boiling) Evaporation (i) It is a process in which a substancechanges its state from the liquid stateto the gaseous state with boiling. (i) It is a process in which a substancechanges its state from the … Read more

The main factors that have an effect on evaporation are as follows: Surface area: If the surface area of evaporating solution is increased, then the amount of liquid that is exposed to air is larger. More molecules can escape with a wider surface area. For example, if we spread out clothes to dry it speeds … Read more

Definition: Evaporation is a surface phenomenon, wherein mass transfer takes place from the surface. It is the process of vaporization of a liquid. In this process, the liquid state of a substance is changing to a gaseous state due to an increase in temperature and/or pressure. It is a fundamental part of the water cycle … Read more

The plate type exchangers have a specialized design well suited for transferring heat between medium- and low-pressure fluids. Welded, semi-welded, and brazed heat exchangers are used for heat exchange between high-pressure fluids or where a more compact product is required. In these exchangers, the media can be heated, cooled or condensed, in a closed space. … Read more
