Fractional distillation of liquid air is a process used to separate the gases found in air. Through the use of low temperatures and high pressures, this process allows oxygen, nitrogen, argon, and other gases to be separated from each other. This process is used in industries such as steel making, chemical production, and even healthcare. It is also used in cryogenic applications such as liquid nitrogen production. The fractional distillation of liquid air can be a very cost-effective way to produce any one of these gases.Fractional distillation of liquid air is a process that involves cooling air until it liquefies and then distilling it into fractions of oxygen, nitrogen, and other components. The process involves boiling the air at high temperatures in a fractionating column and collecting the fractions as they condense. Fractional distillation of liquid air is used to separate oxygen for industrial use and the production of nitrogen fertilizer.
Composition of Liquid Air
Liquid air is a mixture of substances, primarily nitrogen, oxygen, argon and carbon dioxide. It is composed of the same atmospheric gases as regular air, but in a much more concentrated form. The composition of liquid air varies slightly from region to region, depending on the local atmospheric composition. The ratio of nitrogen to oxygen in liquid air is about 79:21. Other gases present in small amounts include carbon monoxide, sulfur dioxide, water vapor and trace amounts of other gases. The amount of each component depends on the source from which it was collected and the method used for collecting it.
The most common method for producing liquid air involves cooling down ambient air until it liquefies. During this process, the oxygen and nitrogen molecules form small droplets that condense together forming a single liquid droplet. This droplet contains all the components present in the original atmospheric air sample but in a much higher concentration than before liquefaction. As each component has different boiling points and freezing points, these components separate when cooled down further to become more concentrated.

How Does Fractional Distillation Work?
Fractional distillation is a process used to separate mixtures of liquids through the application of heat. It works by heating the mixture until all of the components within it reach their boiling points. The vapors that come off are then collected and cooled, which causes them to condense back into liquid form. The different components of the mixture will condense at different temperatures, allowing them to be separated. This process is repeated multiple times, if needed, until the desired fractions are obtained.
The key to fractional distillation is that different components within a mixture have different boiling points. This means that when heated, each component in the mixture will vaporize at its own temperature, and can then be collected separately. To ensure that all of the components have reached their boiling point, fractional distillation usually involves a fractionating column between the source of heat and the collection flask or tank. This is a tube with many plates or trays inside it; as the vapors rise up through it they cool down slightly due to increased surface area exposed to air, causing them to condense and drip down onto lower
Step 1: Obtain Liquid Air
The first step in fractional distillation of liquid air is to obtain liquid air. Liquid air is a mixture of nitrogen, oxygen, argon, and other gases produced by cooling gaseous air to a temperature below its boiling point. This can be done using a cryogenic distillation process or other methods. Once the liquid air has been obtained, it can be used for fractional distillation.
Step 2: Set Up Apparatus
The next step in the fractional distillation process is to set up the apparatus. This involves connecting a collection vessel and condenser to the still head of the apparatus. The still head controls the flow rate of liquid air into and out of the still. It also allows for pressure control and temperature regulation during the distillation process.
Step 3: Heat Liquid Air
Once the apparatus is set up, the next step is to heat the liquid air until it reaches its boiling point. This can be done using an external heating source such as a Bunsen burner or an electric
Fractional Distillation of Gases
Fractional distillation is a process used to separate components of a gas mixture by exploiting differences in their boiling points. The components with lower boiling points will vaporize first, and the higher boiling points last. The vaporized components are collected and separated into individual fractions based on their respective boiling points, allowing for accurate and precise fractionation of the original mixture. By using fractional distillation, it is possible to obtain pure gases from complex mixtures. This is useful in many industrial processes such as air separation, fuel refining, and air purification. Fractional distillation can also be used to obtain valuable chemicals from natural gas or petroleum products.
The process of fractional distillation involves heating the mixture until its components evaporate into a vapor phase. The vapor is then passed through a condenser which cools it back into a liquid phase and separates the different fractions based on their respective boiling points. Each fraction can then be collected separately and either stored or used for further processing.
The gases obtained through fractional distillation can vary depending on the original mixture,
Applications of Fractional Distillation of Liquid Air
Fractional distillation of liquid air is an important process that is used in many industries. It is a process that separates the components of air, such as nitrogen, oxygen and argon, into their desired fractions. The process involves cooling the air to extremely low temperatures, which liquefies it and makes it easier to separate the gases. This process has many applications in various industries including medical, industrial, agricultural and more.
One of the main applications of fractional distillation of liquid air is in medical uses. Oxygen is an essential element for human life and fractional distillation allows for large amounts of oxygen to be extracted from the atmosphere. This oxygen can then be used in hospitals and clinics to help patients with respiratory illnesses or other conditions where they need extra oxygen to survive.
In industry, fractional distillation of liquid air is also useful. Argon can be extracted from air during this process and used for welding purposes. Argon gas helps protect welders from getting burned by shielding them from sparks as they weld metal parts together

Limitations of Fractional Distillation Process
Fractional distillation is an effective and efficient process for separating mixtures of liquids with different boiling points. However, this process has several limitations that need to be considered before deciding whether it is the most suitable method for a given application.
The main limitation of fractional distillation is that it can only be used to separate mixtures of liquids with boiling points that are relatively close together. It cannot be used to separate mixtures of liquids with larger differences in their boiling points, as the temperatures used in fractional distillation are not high enough to vaporise them.
Another limitation of fractional distillation is that it can only be used for relatively simple mixtures, as complex mixtures will not separate properly using this method. This is because the components of complex mixtures tend to have similar boiling points, making it difficult to separate them using a single distillation process.
Finally, fractional distillation requires a large amount of energy and resources in order to operate efficiently. In addition, the process can be time consuming and labour
