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.
Air separation plant is industrial machinery that is used in the generation of oxygen for use in industries. There are numerous air separation plant manufacturers offering the machinery but you must be careful as not all of them provide high quality air separation units. It is advised that you look for acclaimed suppliers that are renowned for offering quality machinery. Most of them use only the latest cryogenic distillation technology, which is based on the process cycle of Linde & Claude, developed in 1930 but has since been greatly improved upon. We are top leading manufacturing company of various industrial gases. The company makes nitrogen plant, air separation plant and oxygen plant manufacturer.Reputed air separation plants not only use the state of the art technology but also offer them at the most competitive prices. The technology used in the fabricating and manufacturing is same as used by the leading European and the US industrial gas plant manufacturers and suppliers. Every air separation unit is known to perform smoothly, require low power and low upkeep expenses besides delivering high yield. Their entire focus is on delivering industrial gas plants that satisfy the needs of the customers. Even their engineers keep in mind the requirements and expectations of customers while building the machinery. The air separation plant cost is kept to the minimum while ensuring that the clients get the full value of the money they spend.
An air separation plant offers oxygen as well as nitrogen both as liquids and gases. The purity of oxygen and nitrogen generated in the air separation unit is 99.7% and 99.9% respectively. It needs no arguing that air separation plant manufacturers place high premium on the quality of air separation plants. For maintaining quality, every component is put through rigorous testing and quality control processes. Most of the air separation plant manufacturers comply with the highest standards of manufactured and are given ISO 9001:2008 and CE certifications. A CE mark on machinery is guarantee of its high quality. The CE is necessary for manufacturers wanting to sell their machinery in the US market.
Air separation plant generates oxygen by tapping air from the atmosphere, which is then run through cleanup system for cleaning impurities. Then, the air is cooled to cryogenic temperature after which is directed into high pressure distillation column where oxygen is deposited at the top of the column and nitrogen at the bottom. The gases are collected and sent into low pressure column where they are distilled until they meet the industrial specifications.
