Air Separation:

1. Air Intake: Air is drawn in from the atmosphere using compressors.

2. Air Purification: The air undergoes purification to remove dust, particles, and contaminants.

3. Cooling and Compression: The purified air is cooled and compressed to liquefy it. This is achieved through multi-stage cooling and compression cycles.

4. Fractional Distillation: The liquefied air is then subjected to fractional distillation, a process that separates the different components of the air based on their boiling points.

5. Separation of Neon: During fractional distillation, neon, along with other gases like helium, oxygen, and nitrogen, is separated. Each gas has a specific boiling point, and they are collected and stored separately.

Purification of Neon:

1. Removal of Impurities: After separation, the crude neon gas undergoes purification to remove residual impurities such as water vapor, carbon dioxide, and other gases.

2. Chemical Treatment: Chemical processes are used to eliminate various impurities. In one method, neon gas is passed through a heated copper oxide bed, which reacts with and removes certain unwanted gases.

3. Cooling and Filtration: The neon gas is further cooled and filtered to remove any remaining impurities.

Storage and Packaging:

1. Compression: The purified neon gas is compressed under high pressure.

2. Storage: Compressed neon gas is stored in high-pressure cylinders or tanks.

3. Packaging: These cylinders or tanks are secured and carefully packaged for transportation and delivery to different industries or locations where neon is needed for various applications, such as lighting, signage, and advertising.

Overall, neon production involves complex processes of air separation, fractional distillation, purification, and storage to obtain pure and high-quality neon gas used in diverse industries.
