Chemical Industry Liquid Oxygen Plant
Description
Technical Parameters
Chemical Industry Liquid Oxygen Plant Core Features
●Highly adaptable to chemical working conditions:
Constructed with corrosion-resistant materials such as 316L stainless steel, equipped with explosion-proof motors and instruments, it withstands the acid and alkali environments and flammable gas risks of chemical workshops, complying with chemical safety regulations.
●Stable oxygen production matching process:
Oxygen production capacity of 500~8000 L/h, purity fluctuation ≤±0.2%, supports linkage and adjustment with chemical production systems to meet dynamic oxygen demand during reactions.
●Significant energy saving and cost reduction:
High-efficiency packed distillation column + waste heat recovery system, unit energy consumption as low as 0.55 kWh/L O₂, saving 35%~50% annual cost compared to purchasing liquid oxygen.
●Convenient intelligent operation and maintenance:
The DCS system integrates chemical production data interaction functions, enabling remote monitoring and fault early warning; core components have a lifespan of 10~25 years, and operation and maintenance costs account for only 1.2%/year of the total equipment price.
Working principle of Chemical Industry Liquid Oxygen Plant
Air Pretreatment
Atmospheric air is compressed to 0.8~1.2 MPa by a compressor and then passes through a high-efficiency oil filter and adsorption dryer to remove oil, water, CO₂, and hydrocarbons (≤5 ppm) to prevent equipment corrosion or explosion.
Deep Cooling
Purified air enters a plate-fin heat exchanger, where it exchanges heat with refluxed cold nitrogen gas, lowering the temperature to -175~-180℃, close to the boiling point of liquid oxygen.
Distillation Separation
Cooled air enters a distillation column, where the boiling point difference between oxygen (-183℃) and nitrogen (-196℃) is utilized to achieve separation through multiple evaporation-condensation processes, producing high-purity liquid oxygen at the bottom of the column.
Liquid Oxygen Storage and Output
Liquid oxygen is temporarily stored in a vacuum-insulated storage tank and pressurized by a liquid oxygen pump or vaporized by a vaporizer, then delivered as needed to chemical reactors, incinerators, and other oxygen-consuming points, with quantity control linked to the production process.

FAQ
1. Is the equipment compatible with the acid and alkaline environment of our workshop? Does it have explosion-proof certification?
The main body of the equipment is made of 316L corrosion-resistant stainless steel. The motor and instruments are Ex d IIB T4 explosion-proof grade, ATEX certified, and can be directly installed in chemical explosion-proof areas, resistant to acid and alkaline vapor corrosion.
2. When linked with the chemical production system, how to avoid the impact of oxygen fluctuations on reaction stability?
The DCS system can access your chemical production PLC data, obtain real-time oxygen demand from the reactor, automatically adjust oxygen production, with a fluctuation response time ≤10 seconds. The storage tank has a 20% buffer capacity to ensure continuous oxygen supply.
3. Does the noise generated by the equipment meet the environmental standards for chemical plant areas?
It adopts a low-noise compressor + soundproof enclosure design, with operating noise ≤82 dB(A), complying with GB 12348-2008 "Emission Standard for Environmental Noise at the Boundary of Industrial Enterprises", and can be directly installed within the plant area.
4. After the equipment is put into operation, will professional personnel be required for operation and maintenance? Can you provide training for our employees?
Routine maintenance requires only basic operations. We provide three free on-site training sessions , along with a detailed maintenance manual and video tutorials. We also offer remote guidance to resolve over 90% of problems later.
5. How do you ensure uninterrupted chemical production in the event of a power outage or equipment failure?
We support connection to the chemical plant's backup power supply, and our storage tanks can provide 2-4 hours of emergency oxygen. In the event of a major failure, we provide temporary liquid oxygen supply services to ensure a smooth production transition.
