Liquefaction of oxygen

This Presentation gives the details about the liquefaction process of oxygen.

1. LIQUEFACTION OF OXYGEN Presented by, Amar m. Borkute

2. Introduction In 1877 Louis Paul Cailletet in France and Raoul Pictet in Switzerland liquefied oxygen in the form of a mist. The liquefaction of the first of the so-called permanent gases heralded the birth of low-temperature research and is often described in the literature as having started a ‘race’ for attaining progressively lower temperatures. Cailletet's liquefaction of oxygen has often been described as starting a ‘race’ for attaining progressively lower temperatures, pursued mainly in laboratories in Cracow, London and Leiden . Usage of Liquid Oxygen Liquid oxygen is a common cryogenic liquid oxidizer propellant for spacecraft rocket applications. It was used in the very first rocket applications like the V2 missile (under the name A- Stoff  and  Sauerstoff ) and Redstone, R-7 Semyorka , Atlas boosters, and the ascent stages of the Apollo Saturn rockets. Liquid oxygen also had extensive use in making  oxyliquit explosives.

3. Current Manufacturing Process Cryogenic Oxygen Plant Plant Modules Warm end (W/E) container Compressor Air receiver Chiller (Heat exchanger) Pre-filter Air purification unit (APU) Coldbox Main heat exchanger Boiler Distillation column Expansion brake turbine Storage Liquid oxygen tank

4. Innovation Proposal The current commercial process is very expensive and restricted process, there is no small scale liquid oxygen generator which will produce liquid oxygen in small proportion. A home made process can be made to liquefy oxygen using Liquid nitrogen which is inspired by the experiment done by CodyDon on the similar topic named Oxygen Liquefier. This is a fairly simple process which can yield fairly pure liquid oxygen. The setup consist of a Container which can accommodate liquid oxygen, copper coil is inserted in the container which will be dipped in the liquid nitrogen completely. The inlet of the coil is connected to a source producing oxygen gas. Once the gas goes through the coil liquid oxygen is obtained at the outlet. The oxygen gas generator can be built pretty easily. T his pure oxygen gas obtained can give a very pure yield of liquid oxygen .

5. Advantages It will be cheap. Faster production of oxygen. Very useful is low scale oxygen requirement. Oxygen can be liquefied at home. Very high purity of liquid oxygen can be obtained. Disadvantages Low production of Oxygen. Leakage and storage problem.

6. Liquid Oxygen is One of the most important gas which has a wide range of application The commercial manufacturing process is pretty expensive the plant itself is very expensive and the product is not available for common usage The homemade method yields very high oxygen since its eliminated the possibility of any other contaminant Liquid oxygen can by synthesized at fairly low price and home made experiment can be done pretty easily. At large scale the same method can be used with the appropriate magnified model the yield will be very pure. This liquid can also be very well used in cryogenic rocket (Considering the fact that there is again a race to moon has started this time between NASA and SPACE X). CONCLUSION
