Product Description
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 generator**, 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 (such as the peak
oxygen demand during the start-up of ethylene units). 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: first, the air pretreatment
system is upgraded to a four-stage purification (dust removal,
deoiling, dehumidification, and sulfur removal) to prevent
petrochemical waste gas (such as sulfur dioxide, hydrogen sulfide)
from poisoning the molecular sieve, and the purification efficiency
reaches 99.9%; second, 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; third, the safety interlock system is linked with the
petrochemical plant's emergency shutdown system. When the oxygen
pressure is abnormal or the gas concentration exceeds the standard,
the system will automatically cut off the oxygen supply and issue
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: the first level is the explosion-proof design of
the whole machine, all electrical components (motors, sensors,
controllers) adopt explosion-proof structures, and the wiring
terminals are sealed with explosion-proof glue to prevent sparks
from leaking; the second level is the oxygen leakage monitoring
system, which is equipped with 10+ oxygen concentration sensors
around the equipment. When the leakage concentration exceeds 23%,
the system will start the exhaust fan and cut off the air inlet to
reduce the oxygen concentration; the third level is the emergency
pressure relief device, the pressure relief valve of the adsorption
tower has a response time of ≤0.1 seconds, which can quickly
release the pressure when the system is overpressured, avoiding
equipment explosion. In addition, the equipment body is equipped
with an anti-static grounding device, and the surface resistance is
≤10⁶ Ω, which prevents static sparks from igniting flammable gases.
These safety designs fully comply with the "Safety Regulations for
Petrochemical Enterprises" and provide a solid guarantee for the
safe operation of the equipment.
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.
