200Nm³/h Modular PSA Oxygen Plant for Coal Chemical Industry pressure swing adsorption oxygen generator

PSA Oxygen Generator (PSA Oxygen Plant) is the core oxygen supply equipment in the coal chemical industry. Based on Pressure Swing Adsorption (PSA) technology, it can efficiently separate oxygen from air, providing stable oxygen supply for processes such as oxidation reactions and coal gasification in the coal chemical industry.

It features core advantages including modular design, adjustable flow rate, stable operation, and strong adaptability. The single-module flow rate of 200Nm³/h can meet the production needs of small and medium-sized coal chemical enterprises. If capacity expansion is required, modules can be directly added without reconstructing the system.

As a mainstream type of pressure swing adsorption oxygen generator, the oxygen produced by this equipment with a purity of 93-95% can perfectly meet the requirements of coal chemical processes. Its characteristics of low energy consumption and low maintenance costs can significantly reduce the operating costs of coal chemical enterprises, making it an ideal oxygen supply choice for the coal chemical industry.

Core processes in the coal chemical industry (such as coal gasification, methanol synthesis, and coal-to-olefins) all require a large amount of oxygen to participate in oxidation reactions. The flow rate, purity, and stability of oxygen directly affect reaction efficiency, product quality, and safe production. Coal chemical enterprises vary greatly in production scale: small and medium-sized enterprises (with a daily coal processing capacity of 500-1000 tons) require an oxygen flow rate of 200-500Nm³/h, while large enterprises need more than 1000Nm³/h.

The modular design of the PSA Oxygen Generator perfectly meets the needs of enterprises of different scales: the single-module flow rate of 200Nm³/h is suitable for small and medium-sized enterprises. If the enterprise expands production later, 2-3 modules can be directly added to quickly increase the capacity to 400-600Nm³/h. Compared with traditional integrated oxygen generators, the expansion cost is reduced by more than 40%, and existing production is not affected. Its oxygen purity of 93-95% can meet the requirements of coal chemical oxidation reactions, with purity stability within ±1%, avoiding reaction imbalance and unqualified product quality caused by purity fluctuations.

In addition, raw coal and process gases in the coal chemical industry contain impurities such as sulfur and dust. The PSA Oxygen Generator adopts sulfur-resistant molecular sieves and an enhanced pretreatment system, which can prevent sulfur and dust from contaminating the molecular sieves, extending the service life of the molecular sieves to 3-5 years and reducing maintenance costs. Its energy consumption performance of 0.38kWh/Nm³ saves more than 25% of electricity costs compared with traditional oxygen generation equipment, significantly reducing PSA oxygen plant cost.

When purchasing PSA Oxygen Generator, coal chemical enterprises should focus on four core aspects: "adaptability, stability, expandability, and safety".

• Confirm the oxygen flow rate (whether the single-module 200Nm³/h matches)
• Verify purity requirements (whether 93-95% meets reaction requirements)
• Check pressure adaptation (whether it adapts to the process system pressure)

• Prioritize products with continuous operation time ≥7000 hours/year and failure shutdown rate ≤1.5%
• Require suppliers to provide cooperation cases in the coal chemical industry
• Confirm equipment supports modular parallel expansion without affecting existing production
• Select products with explosion-proof design and national safety certification

• Select suppliers that can provide on-site installation and commissioning
• Require operator training and regular maintenance services
• Ensure rapid spare parts supply availability
• Minimum warranty period ≥1 year (≥3 years for core components: molecular sieves, fans, valves)

With its advantages of modular design, high adaptability, and stable reliability, the PSA Oxygen Generator has become the mainstream oxygen supply equipment in the coal chemical industry. The single-module flow rate of 200Nm³/h accurately matches the needs of small and medium-sized coal chemical enterprises. Its PSA for oxygen production technology can provide flexible, economical, and safe oxygen supply support for coal chemical processes, helping coal chemical enterprises achieve stable production and cost control.
