Air consists of nitrogen (78%), oxygen (21%) and the inert gas argon (0.9%). The remaining 0.1 % is made of mainly carbon dioxide and the inert gases like krypton, xenon, helium and neon. Now of the gas present in the atmosphere are used in industries. For example, nitrogen is extensively used in the industries and is known as the largest industrially consumed industrial gas. And, oxygen is called the 2nd largest industrially consumed gas. However, the question remains how oxygen and nitrogen are separated from the atmospheric for use in industrial applications.
Separation of Gases from Air
Fractional distillation is used for separating the gases such as oxygen and nitrogen. Carbon dioxide is cooled to -79 C and is removed. Oxygen is liquefied at -183 C and nitrogen is liquefied at -196 C. The mixture of oxygen and nitrogen is moved to the bottom of a fractionating column. As liquid nitrogen boils first, rises to the top of the column and is dispatched off for storage. On the other hand, oxygen settles at the bottom of the column. It is also moved into cryogenic storage.
For industrial applications, oxygen plants, nitrogen plants and air separation plants are available in the market. Industries now like to have on-site air separation plants for meeting their requirements of oxygen and nitrogen. In the fabricating of the plant machinery, only the best quality raw materials are used. Cryogenic distillation technology is used in the making of the machinery that can help generate oxygen with purity up to 99.7% and nitrogen with purity up to 99.99%.Functioning of the plant machinery is based on the process cycle of Linde & Claude, which is developed in 1930s and has since been updated many times. Standard air separation plants are given ISO 9001:2008 and CE certifications.
Cryogenic oxygen plant is an industrial system that is used for producing oxygen for industrial and medical applications. Oxygen plant manufacturers manufacture, fabricate and supply oxygen generation plants. The acclaimed manufacturers use advanced technology in the fabricating of the machinery. Raw materials used in the manufacturing of oxygen plants are also of top quality. The plants are available in different sizes and capacities ranging from 20m3/hour to 5000m3/hour. The different sizes and capacities are offered to meet the varied requirements of customers.
While purchasing a cryogenic oxygen plant, you would rather search for a reputed oxygen plant manufacturer trusted for offering excellent oxygen plant machinery. As an oxygen generation plant costs a lot, it goes without saying that you cannot just buy the machinery from any oxygen plant supplier. There are so many suppliers in the market but you cannot just buy the oxygen equipment from the first oxygen plant exporter you find online. However, finding a reputed supplier on the internet requires using your commonsense intelligently. Things get complicated when you so many companies claiming to sell high quality machinery. Gleaning the best ones is the challenge.
However, it is not a very difficult task if you use your intelligence to good effect. You can formulate devise a criteria depending upon factors such as technology, design, quality, price and after sales service to decide whether the manufacturers produce high quality machinery or not. It is better if you have got sound knowledge of oxygen generation plant machinery. The important factor is technology used in the industry. Sound knowledge of the machinery helps you to identify quality machinery from the bad one. High quality cryogenic oxygen plants are fabricated using the latest cryogenic distillation technology. Technology is the most important factor in the making of an oxygen plant as it decides the efficiency and costing of the machinery.
Other factors are also equally important and cannot be ignored. Design is equally important as a solid design of the oxygen plant machinery has a great bearing upon the performance and durability of the machinery. Acclaimed oxygen plant manufacturers pay a great deal of attention to the designing of the machinery. Apart from designing and technology, quality is one factor that you must enquire about. Oxygen generation plant machinery must be ISO 9001:2008 and CE certified. A CE mark on a machine is a guarantee of its high quality.
