Objectives and Applications of Heat Transfer.

 

Objectives Of Heat Transfer:

  • Heat is a form of energy that can be used in many forms to perform industry scale operations.

  • Electricity and steam are two main sources of the energy that are used in industries.

  • Knowledge of heat transfer is essential in order to avoid heat loss.

  • Knowledge of heat transfer helps in designing efficient and economical plants.

Applications of Heat Transfer:

  • Heat transfer has numerous applications in the industry, the notable applications related to the pharmaceutical engineering are as follows,

  1. Crystallization:

    • It is an important process employed for the purification of pharmaceutical products.

    • Application of heat to a saturated solution of a substance brings supersaturation causing the crystallization of the substance.

  2. Distillation:

    • In this process the liquid mixture is boiled and the mixture components are separated in the form of vapours and collected separately.

    • For boiling the mixture, heat is used.

  3. Drying:

    • It simply means removal of moisture or a solvent, which can be achieved by application of heat.

  4. Evaporation:

    • In this pharmaceutical process heat is applied to a liquid to convert it into vapors which can be removed.

    • This process is used for concentrating the preparations particularly vegetable extracts

  5. Sterilization.

    • It is the complete removal of microbes from any given object or substance.

    • Dry as well as wet forms of heat are employed to achieve sterilization of pharmaceuticals.

Rate of Drying Curve.

  Definition Drying is defined as the removal of liquid from a product usually with application of heat. Rate of Drying Curve. Drying process can be divided into three periods Initial Adjustment Period. Constant drying rate period. First falling drying rate period. Second falling rate period. Initial Adjustment Period (A-B): Also called the “ Heating up” period . In this period the substance gets heat and increases in temperature. Drying has not yet started. Constant drying rate period (B-C): During this period the temperature of the solid and the rate of drying remain constant. The moisture evaporating from the surface is replaced by water diffusing from the interior of the solid at a rate equal t o the rate of evaporation.  The moisture content at the end of constant rate (point C) is referred to as the critical moisture content (CMC).  At CMC, dry spots start appearing and drying rate starts falling . First falling drying rate period (C-D): This period is also called ...

Heat Exchangers and Heat Interchangers.

  In pharmaceutical industries many types of equipments are used for transfer of heat, they can be classified as follows, Heat Exchangers. Heat Interchangers. Heat Exchangers: These devices are used for transferring heat from a fluid (Hot Gas or Steam) to another fluid (Liquid) through a metal wall. Heat Interchangers: These devices are used for transferring heat from a One liquid to another liquid or one gas to another gas through a metal wall. HEAT EXCHANGERS; The equipment used for heat transferring are known as heat exchangers. Some of the processes that involves heat transfer in pharmaceutical industries are: Preparation of starch paste (in steam jacketed kettle). Crystallization. Evaporation. Distillation.  Classification of heat exchangers On the basis of transfer of heat, heat exchangers are classified as: Direct transfer type:  The hot and cold fluids are separated by a metal wall through which the heat is transferred from hot fluid to cold fluid. E.g. shell and ...

Flash Distillation.

  Principle: When a hot mixture is allowed to enter from a high-pressure zone into a low pressure zone, the entire liquid mixture is suddenly vaporized. This process is known as flash vaporization .  During this process, the chamber is cooled.  The less volatile fraction is condensed and the more volatile component remains in the vapor phase .  This process requires time, hence liquid and vapor are kept in intimate contact until equilibrium is achieved. Flash distillation is also called equilibrium distillation because separation of two liquids takes place when liquid and vapor phases are at equilibrium. Equipment used for Flash Distillation: Construction: It consists of a pump, which is connected to a feed reservoir.  Pumps help in pumping the feed into the heating chamber.  The heating chamber is heat supplied by steam.  The other end of the pipe is directly introduced into the vapor-liquid separator through a reducing valve.  The vapor outlet...
