VAPORIZER IN PROCESS INDUSTRY

Vaporizers are heat exchangers which are specially designed to supply latent heat of vaporization to the fluid. In some cases it can also preheat the fluid then this section of vaporizers will be called upon preheating zone and the other section in which latent heat is supplied; is known as vaporization zone but he whole assembly will be called upon a vaporizer. Vaporizers are called upon to fulfill the multitude of latent-heat services which are not a part of evaporative or distillation process. There are two principal types of tubular vaporizing equipment used in industry: Boilers and Vaporizing Exchangers . Boilers are directly fired tubular apparatus, which primarily convert fuel energy into latent heat of vaporization. Vaporizing Exchangers are unfired and convert latent or sensible heat of one fluid into the latent heat of vaporization of another. If a vaporizing exchanger is used for the evaporation of water or an aqueous solution, it is now fairly conventional to call...

DISTILLATION COLUMN IN CHEMICAL INDUSTRY

In process industries, it is often desired to separate the components of a liquid mixture. The easiest way is to carry out this separation is by distillation. This unit operation makes use of the difference in the boiling point or the relative volatilities of the components. Distillation is considered to be the preferred separation technique if the relative volatility difference between the two key components (that are required to be separated from each other) is greater than 1.2. Distillation is carried out by the use of ESA (energy as separating agent). The addition of heat to the system raises the temperature of the system and causes the more volatile component to go to the vapor state preferably as compared to the less volatile component. On the removal of heat, the condensation occurs and the less volatile component is preferentially condensed. As the addition and subsequent removal of heat continues, the vapor phase become rich in the more volatile component and the liquid ph...

COOLING TOWER IN CHEMICAL INDUSTRY

Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere They represent a relatively inexpensive and dependable means of removing low-grade heat from cooling water.
