Help: Method for preparing oxygen-enriched gas for combustion
Thread Content
Oxygen-enriched combustion is being considered as a solution to a problem in an oil refinery. The requirements for oxygen-enriched air are as follows: 1. Oxygen content: 40-45% ； 2. Pressure: 2kPa ； 3. Flow rate: 10,000 nm3/hr; 4. Continuous operation. Could that expert provide some guidance? Can the oxygen emitted during nitrogen production in air compressor stations be recycled to meet the requirements? What is the approximate investment for an oxygen generation unit alone? What is the power consumption? Thank you! :handshake

The requirements for oxygen-enriched air are as follows: 1. Oxygen content: 40-45% ； 2. Pressure: 2kPa ； 3. Oxygen flow rate: 10,000 nm3/hr; the cost of an oxygen generation unit with an oxygen flow rate of 10,000 nm3/hr is approximately 45.5 million yuan. This device can operate continuously throughout the year; under normal conditions, it only requires maintenance for one week per year.
The following are merely personal opinions: For 1000 Nm3/h at 40-45% oxygen concentration, the VPSA method is suitable for production, but it is not necessary to use solely VPSA equipment. Because your concentration is not high. Air distribution can be considered. First, the VPSA unit produces oxygen at a high concentration. Mix it with air again. In this way, the oxygen in the air is utilized effectively. The scale of the VPSA equipment is over 3,000 units. The cost is probably around 20 million or so~~ It depends on the specifications; I’m not sure if it can help you. . Feel free to contact me if you have any questions~~
Our company holds technical patents in this area for oxygen-enriching equipment. As well as the recovery and utilization of exhaust gases from nitrogen generators. Chengdu Power Source: 13880503749 – Feel free to ask questions
What was said on the 3rd floor makes quite sense; it’s also possible to use nitrogen production and oxygen enrichment to supply a mixture of oxygen with high purity.
