200Nm³/h 99.2% High-Purity VPSA Oxygen Generator for Petrochemical Industry
The petrochemical industry, involving processes such as catalytic cracking, hydrofining, and ethylene oxidation, has extremely strict requirements for oxygen supply—high purity to ensure reaction efficiency, stable output to avoid process interruption, and explosion-proof performance to adapt to flammable and explosive working conditions. The VPSA oxygen generator (Vacuum Pressure Swing Adsorption Oxygen Generator), as a high-end industrial oxygen generator, relies on pressure swing adsorption for oxygen production technology to separate air through high-performance molecular sieves, achieving continuous production of high-purity oxygen.
Compared with cryogenic oxygen production, it has the advantages of short start-up time, low energy consumption, and flexible adjustment of oxygen purity; compared with small PSA oxygen generators, it is more suitable for large-scale oxygen demand scenarios in petrochemical plants. This 200Nm³/h 99.2% high-purity VPSA oxygen generator is tailor-made for petrochemical processes, with explosion-proof, corrosion-resistant, and high-stability characteristics, becoming a core supporting equipment for efficient and safe production in the petrochemical industry.

Why VPSA Oxygen Generator Becomes the Core Equipment for Petrochemical High-Purity Oxygen Supply?
The petrochemical industry's oxygen demand has three characteristics: large scale (hundreds of Nm³/h), high purity (≥99%), and strict safety requirements. The VPSA oxygen generator perfectly solves these pain points. Compared with cryogenic oxygen production, it avoids the problems of long start-up time (cryogenic equipment takes 24-48 hours to start) and difficult adjustment of oxygen production, and can quickly respond to the load changes of petrochemical processes.
Compared with the PSA oxygen generator, the VPSA oxygen system adopts vacuum regeneration technology, which reduces energy consumption by 25%-35% under the same output, and the oxygen purity can stably reach 99.2%, which is difficult for ordinary PSA equipment to achieve. In addition, its modular design can be expanded according to the capacity expansion of petrochemical plants (for example, two 200Nm³/h units can be combined to form a 400Nm³/h system), which is more flexible than the fixed-capacity cryogenic oxygen production equipment. For petrochemical plants with high safety requirements, the integrated explosion-proof design of the VPSA oxygen generator eliminates the potential safety hazards of traditional oxygen supply methods.
PSA Technology for Oxygen Generation Upgrade: VPSA's Adaptability Design for Petrochemical Processes
The PSA technology for oxygen generation has been continuously upgraded in the petrochemical field, and the VPSA oxygen generator has formed three core adaptations:
- The air pretreatment system is upgraded to a four-stage purification (dust removal, deoiling, dehumidification, and sulfur removal) to prevent petrochemical waste gas from poisoning the molecular sieve, with purification efficiency reaching 99.9%
- The oxygen purity control adopts a dual-sensor monitoring system (zirconia sensor + gas chromatography), which can monitor the oxygen purity in real time with an error of ≤0.1%, ensuring the stability of the reaction process
- The safety interlock system is linked with the petrochemical plant's emergency shutdown system. When oxygen pressure is abnormal or gas concentration exceeds standards, the system automatically cuts off oxygen supply and issues an alarm to avoid explosion accidents
In addition, the equipment is equipped with an online ash cleaning system to adapt to the high-dust environment of the petrochemical production workshop and reduce manual maintenance workload.
Safety Guarantee of VPSA Oxygen System in Petrochemical Explosive Environments
The petrochemical workshop is a typical flammable and explosive environment, and the safety of the VPSA oxygen system is the top priority. This VPSA oxygen generator has built a three-level safety barrier:
- First level: Explosion-proof design of the whole machine, all electrical components adopt explosion-proof structures, and wiring terminals are sealed with explosion-proof glue to prevent sparks from leaking
- Second level: Oxygen leakage monitoring system with 10+ oxygen concentration sensors around the equipment. When leakage concentration exceeds 23%, the system starts the exhaust fan and cuts off the air inlet
- Third level: Emergency pressure relief device with pressure relief valve response time of ≤0.1 seconds, quickly releasing pressure when the system is overpressured
In addition, the equipment body is equipped with an anti-static grounding device, with surface resistance ≤10⁶ Ω, preventing static sparks from igniting flammable gases. These safety designs fully comply with the "Safety Regulations for Petrochemical Enterprises" and provide a solid guarantee for safe operation.
Conclusion
The 200Nm³/h 99.2% high-purity VPSA oxygen generator has become the core oxygen supply equipment for the petrochemical industry with its high purity, low energy consumption, explosion-proof and stable characteristics. It relies on advanced pressure swing adsorption oxygen plant technology to perfectly match the oxygen demand of petrochemical processes such as catalytic cracking and ethylene oxidation, and solves the pain points of traditional oxygen supply methods such as high cost, poor safety, and difficult adjustment.
For petrochemical enterprises, selecting such equipment not only improves production efficiency and product quality, but also reduces comprehensive operating costs and safety risks, which is of great significance for promoting the green and safe development of the petrochemical industry. With the continuous upgrading of PSA technology for oxygen generation, the VPSA oxygen generator will be more intelligent and efficient, making greater contributions to the high-quality development of the petrochemical industry.
