Distillation the Process of Water Purification




Water distillation has been used by people for thousands of years. The process of water distillation is used to purify water through distillation equipment. Water distillation is used to remove bacteria, viruses, microorganisms and other contaminants from water. The process of distillation uses the source of heat through distillation equipment to boil water and to generate vapors from water. With the help of a higher boiling point, the pure water molecules and contaminants get separated further. Here’s the brief process of distillation using the distillation equipment.

Water gets heated through distillation equipment till the time it starts getting evaporated. The temperature of the boiling water is then kept constant. The constant temperature then continues water vaporization but at the same time helps to prevent evaporating the drinking water contaminants. That means, water is getting boiled at the same temperature so that the evaporation of drinking water contaminants does not happen. The evaporated water is then collected in distillation equipment and transferred through a tube system to other distillation equipment. After that the distillation equipment which is used to provide heat is removed. The water vapors come back to its original liquid form.

The process of distillation removes most of the bacteria and viruses. This water we use for our day to day life.

Water is distilled to remove impurities such as salt from sea water. Because distillation is able to separate substances with the help of distillation equipment, this procedure is used in various processes including production of alcohol, separation of crude oil into petroleum products such as diesel and gasoline. The methods of distillation used in industries and laboratories are the variations of the basic process of distillation. The distillation equipment used for performing a small process and in sprawling oil refineries and warehouse sized craft liquor companies are almost the same. The main differences between them are their cost and the volume of their production.

The process of distillation is also widely used in industries for the manufacturing of various chemical and medical products such as medicines, vaccines, and intravenous injections.

Distillation and Distillation Equipment




In simple language, distillation is a method of separating the components of a liquid mixture by using the process of boiling and condensation. The equipment used in the process of distillation is known as distillation equipment. Distillation is considered a unit operation because it comes under the larger chemical process and it can only be done with the help of distillation equipment. Distillation equipment has various uses commercially. For example, water is distilled by distillation equipment to remove impurities such as salt from seawater. Distillation equipment is also used for fermentation solutions to produce alcohol and acids. Distillation equipment is a distillation machine which is used to recycle the solvent.

Distillation equipment is used for the distillation of the solvent which is done by outermost heating the solvent. The distillation equipment used for heating is filled with diathermia oil. The vapors produced by distillation equipment are further transferred to a condenser.  The solvent is collected for reuse. Distillation is one of the most reliable and cost-efficient methods for chemical separation. It is widely used in industrial processes. There are so many industries that use distillation equipment for the process. Some of them are general chemical production, petrochemicals, renewable fuels, pharmaceuticals, food processing, mining, agriculture and many more.

Distillation involves both heat and mass transfer. Although, there are other procedures also available in the market for the separation of chemical compounds distillation has proven the most reliable and economical procedure. The distillation equipment is designed on the basis of relative volatility and activity coefficients. Relative volatility is the measurement of the vapor pressures of the components. The activity coefficient is used for the calculations of the final deviation. The design of distillation equipment is a very important task to make the procedure successful. Qualified engineers are used for the designing of distillation equipment.

Some of the types of distillation process are simple distillation, short path distillation, molecular distillation, fractional distillation, thin-film distillation, and spinning band distillation.

EVAPORATORS AND ITS TYPES


What is an Evaporator??


An evaporator is a device used for the process of turning the form of a substance from liquid to gaseous form or vapor and the process is known as evaporation.

Types of Evaporators:-


Falling Film Evaporators:-


The falling film evaporator is a type of evaporator which is used for heat exchanger. It consists of a vertical shell and a tube heat exchanger. The concentrated liquid is fed at the top of the tube and then flows down to the surface tube as a thin film. As it gets heated further, the vapors get generated. It increases the heat transfer and the vapor and liquid get separated further.




Rising Film, LTV (Long Tube Vertical) Evaporators:-


The rising film evaporator is very similar to the falling film evaporator. It’s just the opposite of falling film. It also consists of a vertical shell and a tube heat exchanger and it is also used for heat exchanging. The concentrated liquid is fed at the bottom of the tube. As the heat increases further the vapors get generated and lift the liquid upward. As a result the vapor and liquid get separated further.




Forced Circulation Evaporators:-


Force circulation evaporator is a type of evaporator which is used to separate mixture which is not possible by normal evaporating unit. In normal circular evaporator the velocity of liquid flow is 0.3 to 1m/s but forced circular evaporator increases the velocity of liquid flow to 2 to 6m/s. It contains a circulation pump and because of this it is used for both heat exchanger and flash separation. It separates the mixture without using normal conventional boiling. It consists of a vertical shell and heat exchanger tube with a centrifugal pump.




Plate Evaporators:-


Plane evaporators consist of a plate and frame heat exchanger and are mainly used in food and beverage industry. Plate evaporator is a type of evaporator in which a thin film of liquid is passed and flows between the plates for the process of evaporation. It is typically used for fruit juices, fruit puree, syrup, coffee, milk.




Thermal Vapor Recompression(TVR):-


Thermal vapor recompression evaporator is a type of evaporator which is used as a thermo compressor to reduce the steam required for the process of evaporation. A vapor steam is compressed to a higher temperature and pressure by a steam jet pump.




Mechanical Vapor Recompression (MVR):-


Mechanical vapor recompression is a type of evaporator in which the water vapor is compressed which results in rise of temperature and pressure. The rise in temperature makes the temperature difference between the vapor and the fluid. The further heat transfer results in heat exchanger. The compressed vapor is again fed back to generate more steam. This is energy efficient and energy recovery process.
