This is second type of Deoxo unit is with additional after cleaning using copper for endothermic reaction for removal of extra oxygen, the moisture and hydrogen contents and maintained upto 1PPM level. This Ultra pure nitrogen gas finds application in electronic, synthetic fiber and optical fiber industries. This De-Oxo unit needs two externally heated filled with copper as catalyst for the endothermic reaction : O2 + 2Cu----2CuO The loaded copper bed can be regenerated by adding hydrogen during the regeneration step. For this two step process (Deoxidization and regeneration), two reactors are necessary to achieve a continuously operating De-Oxo system. The nitrogen form the PSA system with the remaining oxygen passes one of the reactors without adding hydrogen. ON passing through the reactor, the oxygen is removed by reacting with the copper surface, The advantage of the Deoxo unit based on the copper is that the high purity nitrogen leaves the unit absolutely dry & without any remaining hydrogen.

Technology The compressed air is passed through a Twin Tower PSA module interconnected with automatic changeover valves. At the bottom of PSA towers, Activated Alumina is provided which has tendency of adsorbing moisture from compressed air. After passing through this bed of Activated Alumina air gets dried. Supply of dry compressed air from this layer of desiccant (activated alumina) will be continuous without any interruption. Dried compressed air will now come in contact with bed of carbon molecular sieves (CMS). Carbon Molecular Sieves are special grade of adsorbant which have the property of preferential adsorption of oxygen molecules. At a time one tower remains under nitrogen production cycle, whereas the other tower undergoes regeneration which is achieved through depressurization of the tower to atmospheric pressure. The two towers of PSA modules are inter-connected with automatic changeover valves through pneumatic signal given by solenoid valve which in turn get the electrical signal from the timer provided in the control panel. The changeover time cycle will be 1 + 1 minute. The outgoing nitrogen gas is sent to a surge vessel where the minimum nitrogen pressure will be maintained with the help of Back pressure Regulator. The product nitrogen will now be sent to the consumer point through a pressure reducing valves at required pressure. Salient Features: 1. The PSA type gas generator is fully automatic and the gas of proper specification is made available within short period after start-up. 2. This type of gas generator does not require any fuel. 3. Since the feed stock for this gas generator is air, there is no problem like soot formation or presence of Co2 etc. – the common problem in fuel combustion based gas generator. 4. The gas generator is very compact requiring very small floor area. 5. Depending on the pressure in the nitrogen storage tank, the gas generator keeps running with ON/OFF operation like compressed air installation. Therefore, the gas generator would work only to the extent of meeting your gas requirement as and when needed.

We are offering psa nitrogen plant. Molsieve is a leading manufacturer, supplier, and exporter dealing in premium quality nitrogen gas generation plant. Our world class nitrogen gas generation plant works on psa technology. Psa stands for pressure swing adsorption, which works on the air separation technology and separates nitrogen and oxygen molecules from rich compressed air. Here, the oxygen is adsorbed to its equilibrium value much faster than nitrogen as oxygen which is smaller in size diffuses much faster in carbon molecular sieves than nitrogen. Molsieve make psa nitrogen gas generation plants are of premium quality, durable and maintenance free. As our psa nitrogen gas genration plant are custom made, it can be adjusted to give the desired nitrogen purity for your process and application. We manufacture psa nitrogen gas generation plant with purity ranges of 98% to 99.9999% . Following are the psa nitrogen gas generation plant models to produce different nitrogen purities as per your requirement: model atlp and athp: this is the basic and simplest model of nitrogen gas generator, which produces commercial grade nitrogen upto 99.9 % purity. Still if further high nitrogen gas purity is needed then one has to add more quantity of carbon molecular sieves (cms) where purity of 99.999 % can also be achieved. Always higher the purity. Higher would be the investment and higher would be its running cost. These models are strictly recommended upto the purity of 99.9 % . Application : blanketing in process plant, chemical & petro-chemical industries. Storage against oxygen and moisture. Pressure transfer of sensitive chemicals. Packing against oxidation contamination in food, dairy, pharmaceutical. Fire control in coal mines. Poy / pfy process.
