OMEGA AIR: O-GEN - Oxygen generators OXYGEN DEMAND PATTERNS Where the consumption rate as a function of time is essentially constant, a PSA oxygen system is an excellent fit for a steady flow pattern. The PSA unit size can easily be matched to the measured or estimated consumption rate. Furthermore, oxygen production will be most economical if the unit operates continuously near or at its full capacity. Oxygen behaves differently to air, compressed air, nitrogen and other inert gases. Even a small increase in the oxygen level in the air – to just 24 % can create a dangerous situation. It becomes easier to start fire, which will burn hotter and more fiercely than in air. Oxygen is also very reactive. Pure oxygen can react violently with common materials such as oil and grease. Materials such as textiles and rubber will burn vigorously in oxygen. A PSA system is not a good fit for processes with periodic flow pattern, where flow is characterized by peaks and valleys as a function of time. An onsite generator with such variable consumption, particularly if it is sized for a peak flow, will operate at partial capacity or idle for a significant amount of time. This will results in high operating costs and operational inefficiency. However, if the duration of the valleys is short, a PSA combined with a large product buffer tank may be sufficient. A PSA system can be sized to handle most of the oxygen requirements, supplemented with liquid oxygen during peak-demand periods. Oxygen flow Operating press.: up to 13 barg PDP: +3°C / -40°C (lower on request) Capacity: Up to 35 m3/min (higher on request) Oxygen, is present in the air with concentration around 21%. Oxygen is at atmospheric conditions always present in gas phase with no odour, colour or taste. It is a highly reactive substance, reacting with almost all elements, except inert gases. This is why it is used in a variety of applications: aquaculture, feed gas for ozone generators, glass blowing, leaching, NOx reduction for fuel burners, oxygen lancing, welding and health care. CUSTOM MADE CONTAINER NITROGEN AND OXYGEN STATIONS Operating press.: PDP: Capacity: on request on request on request PRESSURE SWING ADSORPTION The first step in the PSA process is compressed air passing through a combination of dryers, filters and an activated carbon tower with the purpose of removing dust, entrained oil and water. The purified air is then directed to one of two adsorption vessels that are packed with 5% of activated alumina (AA) and 95% of molecular sieves (MS). The remaining impurities such as carbon dioxide and residual moisture are adsorbed by the activated alumina (AA) at the entrance of the adsorbent bed. When the MS is at high pressure, it selectively adsorbs nitrogen, allowing oxygen to pass through it at the desired purity level. While one vessel is at high pressure to produce oxygen, the second vessel is depressurized to remove the adsorbed nitrogen, which is then vented to the atmosphere. GENERATING OXYGEN GAS Oxygen gas can be produced by either separation of gaseous air using adsorption (PSA) or fractional distillation of liquefied air using cryogenic methods. OXYGEN USE BY PURITY PSA can produce oxygen at various ranges of purities. Typically purity of the oxygen produced by PSA is from 90% to 95% of the oxygen. The lower the purity, the lower is the cost of oxygen production. Field of use The automatic switching between adsorption and desorption between the two beds enables the continuous production of oxygen. By adjusting the size of the air compressor and adsorption vessels containing the MS, a large range of flow and purity combinations can be met. PSAs can economically produce oxygen gas at flowrates from less than one cubic meter per hour to greater than a few hundred cubic meter per hour at purities ranging from 90% to 95%.

Robust SIEMENS PLC assures reliable and stable operation and offers variety of settings. The controller is equipped with LCD display which provides all the necessary information about the operation. High quality zirconia oxygen sensor is available as an option. Molecular sieve material is fixed in the column to prevent fast aging and inconveniently dusting. Added activated alumina at the entrance of adsorbent bed protect molecular sieve from unexpected liquid intake. High efficiency inlet and outlet filters Standard versions of O-GEN generators are equipped with high efficiency filters. Super fine coalescing filters at the inlet prevents contamination of the adsorbent material while a dust filter at the outlet intercepts the dust generated by the process.
