We are a leading company with skilled workforce and well equipped air separation manufacturing units to design and manufacture advanced and fully automatic air separation plant. The systems are popular all over the world in terms of reliability, functionality, performance and ease of use. With the capacity ranging from 50 m3/hr to 10,000 m3/hr, the systems offer both oxygen and nitrogen in liquid as well as gas form. The purity of oxygen is upto 99.7% and nitrogen upto 99.99% respectively.
One of the most appreciable achievements of our company is approval for CE certification. The certification clarifies that we are an organization, which manufactures and exports technologically advanced and high quality systems. Being quality conscious, we are approved organization for exporting our products and services to the USA and European countries. While manufacturing the systems, our quality controller team takes utmost care of quality, safety, health, money and environmental protection. We understand the requirement of our clients and thus provide safe and economical plants equipped with the latest technology.
Process Description of Air Separation Plants
COMPRESSION OF ATMOSPHERIC AIR : In the very first stage, atmospheric air is compressed at a very pressure of 5-7 bar (kg/cm2). Air can be compressed at such low pressure by advanced and trouble free rotary compressors.
PRE COOLING SYSTEM : The second stage of the process uses a low pressure refrigerant for pre-cooling the processed air to temperature around 12 deg C before it enters the purifier.
PURIFICATION OF AIR BY PURIFIER : The air enters a purifier consisting of twin Molecular Sieve driers, working alternatively. The Molecular Sieves remove the Carbon dioxide & moisture from the processed air before the air enters Air Separation Unit.
COOLING OF AIR BY EXPANDER : The air has to be cooled to sub zero temperatures for liquification & the cryogenic refrigeration & the cooling is provided by highly efficient expander, which cools the air to temperature almost below -165 to-170 deg C.
SEPARATION IF LIQUID AIR INTO OXYGEN AND NITROGEN BY AIR SEPARATION COLUMN : Oil free, moisture free and Carbon Dioxide free air enters into low pressure fin type HEAT EXCHANGER where the air is cooled below sub zero temperatures by air expansion process in the expander. Air gets liquefied when it enters the air separation column & gets separated into oxygen & nitrogen by the process of rectification.
COMPRESSION OF OXYGEN &FILLING OF IN CYLINDERS : The final product in the form compressed Oxygen/Nitrogen goes to the high pressure oxygen cylinders at 150 bar or upto higher as required. This can be done by liquid oxygen pump is same models. We can use oil & water free compressor.
