PSA Oxygen Generator

Oxygen production：1~300Nm³/h(Standard State). Oxygen purity：93%±3%(National standard oxygen content). Oxygen pressure：0.01~0.6Mpa(Gauge pressure is stable and adjustable). Oxygen dew point：-40℃~-70℃(Atmospheric Dew Point).

· Metal Fabrication & Welding:Oxygen is a must for oxy-fuel cutting, welding, and brazing. Pick the right purity, and you’ll notice better flame temperature and faster cutting in steel shops and manufacturing plants.

·‍‌‍‍‌ Water & Wastewater Treatment: Oxygen injection is the key factor that makes biotreatments very effective, also it accelerates the oxidative processes, and it is very helpful in aerobic digestion; all these are valid whether we are talking about city or industrial wastewater plants.

· Glass Manufacturing: Oxygen addition to glass melting furnaces improves the combustion efficiency, reduces NOx emissions, enhances melting quality, and is capable of cutting the fuel consumption by 20-40% (these figures represent the typical usage of these types of generators in the industry).

· Pulp & Paper Industry: Employing oxygen in delignification and bleaching stages reduces the use of chemicals, lessens pollution, and improves paper quality in pulp mills.

· Chemical & Petrochemical Production: The device is basically required in oxidation reactions, catalyst regeneration, and combustion intensification in a plant producing ethylene, methanol, and other chemicals.

· Aquaculture & Fish Farming: Oxygen apparatus can maintain the dissolved oxygen level in fish tanks, hatcheries, as well as in the transport of fingerlings. The takeaway is that if a reasonable fish density is kept, the fish will remain healthier.

How to Pick the Right Purity & Flow Rate

Knowing the right oxygen purity and flow is very important not only for a smooth process but also for saving money. Our technical team has a simple method to help you make a choice:

Oxygen Purity Tips:

· 90-93% Purity: Is suitable for combustion reinforcement, wastewater treatment, and aquaculture. Moderate oxygen enrichment provides you with real advantages without incurring too high a cost.

· 93-95% Purity: It is enough for the majority of metal cutting/welding, glass manufacturing, and chemical processes on the basic level. It is a good balance between performance and operating costs.

· 95-99% Purity: It is a requirement for welding that is highly specialized, some chemical oxidation processes, and advanced wastewater treatments – where oxygen plays an extreme role to obtain the final result.

· 99%+ Purity: It is a necessity for processes related to pharmaceuticals, high-accuracy laser cutting, and specialized laboratory processes. Just to let you know: typically going beyond 99% purity requires additional purification stages and both the initial and the running costs are higher.

Flow Rate Calculation:

·‍‌‍‍‌‍‌‍‍‌ Before anything else, add up all the oxygen consumptions that are done at the same time, and then, for a future growth, put a 15-20% safety margin—this is your maximum demand.

· You should also take into account fixed, daily and occasional, short periods of high demand while making a decision on the equipment size.

· Figure out whether a single large generator will be able to do the job better or if it is good to have a few smaller, modular units—this largely depends on how the oxygen requirements in your plant ‍‌‍‍‌‍‌‍‍‌change.

· Do not forget about altitude: for every 1,000 feet above sea level, the capacity of oxygen generation is reduced by approximately 3% (this is according to common technical specifications).

Installation & Site Prep:

· The ventilation of the generator room should be such that it keeps the oxygen levels below 23.5% (this is in accordance with safety standards).

· Install oxygen sensors in closed areas where the generator is operating.

· Use air that is clean, dry, and oil-free, and properly filtered (0.01-micron coalescing filters are suggested for optimum results).

· The temperature of the room should be kept from 40°F (4°C) to 115°F (46°C) if the adsorption is to be continuous and ‍‌‍‍‌‍‌‍‍‌stable.

· Leave at least 3 feet/1 meter of space around the equipment—this is standard for maintenance.

Maintenance Needs:

· Replace inlet air filters every 2,000-4,000 operating hours—depends on how clean the air is at your site.

· Check and replace molecular sieve material every 5-10 years, based on how you’re using the equipment.

· Inspect valve assemblies every 6-12 months to make sure they’re working properly.

· Oxygen‍‌‍‍‌‍‌‍‍‌ purity sensors should be calibrated one time every year in order to maintain accurate readings.

·It is very good for you to keep proper maintenance records: note down the purity readings, the flow rates, and the time when you changed the parts.

Saving Energy:

· Put‍‌‍‍‌‍‌‍‍‌ variable frequency drives (VFDs) on compressors so the power matches the amount of oxygen you ‍‌‍‍‌‍‌‍‍‌require.

· If your plant requires thermal energy, why not installing heat recovery systems?

· Install automated controls that enable the equipment to idle or shut down when the demand is low.

· Frequently measure the system's efficiency as compared to your baseline figures.

Following Regulations:

· Conform to OSHA 29 CFR 1910.104 (rules for the storage and handling of oxygen) strictly.

· In case of medical-related uses, refer to NFPA 99 (Healthcare Facilities) guidelines.

· Comply with the local building codes when setting up the oxygen ‍‌‍‍‌‍‌‍‍‌generator.

· Keep all necessary documents for insurance and regulatory inspections.
