How it works

NEWTEK's PSA oxygen generator uses advanced pressure swing adsorption technology. Under pressurized conditions, impurities such as nitrogen and carbon dioxide in the air are selectively adsorbed by the adsorbent, while oxygen can pass smoothly and be enriched into high-purity oxygen. When the adsorbent reaches saturation, the adsorbent is desorbed by reducing pressure to release the adsorbed impurities and restore the adsorption capacity for the next round of adsorption. This periodic process of pressurized adsorption and decompressed desorption achieves continuous and stable oxygen production, and can efficiently provide the required oxygen for chemical plants.

Stability guarantee

In terms of stability, we have optimized the design from multiple dimensions. The equipment uses high-quality imported adsorbents, which have the characteristics of large adsorption capacity, high adsorption selectivity, good mechanical strength, stable chemical properties, etc., and can withstand long-term frequent adsorption and desorption cycles, and are not easy to pulverize and age. The control system uses advanced PLC automatic control technology, which can monitor the operating parameters of the equipment in real time, such as pressure, flow, purity, etc., and automatically adjust the switch and adsorption time of each valve according to the preset program. In addition, the equipment is also equipped with multiple safety protection devices, such as overpressure protection, overcurrent protection, fault alarm, etc., so that timely measures can be taken in case of abnormal conditions.

Q: In the complex and changeable working conditions of chemical plants, how can your PSA oxygen production equipment ensure that it can still stably produce oxygen that meets the purity requirements under different temperature and humidity conditions? Especially in extreme weather conditions with high temperature and humidity in summer and low temperature and dryness in winter, how will the performance of the equipment be affected, and what are the countermeasures?

Our PSA oxygen generator has designed multiple protection mechanisms for complex working conditions. The equipment is equipped with an efficient pretreatment system that can deeply dry the incoming air under different humidity conditions to ensure that the humidity of the air entering the adsorption tower is maintained within an appropriate range. In terms of temperature, the oxygen generator is equipped with an intelligent temperature control system. When the temperature is high in summer, the cooling device automatically starts to ensure that the key components of the equipment operate within the normal operating temperature range; when the temperature is low in winter, the heating element maintains the necessary temperature of the equipment to prevent the adsorption performance from decreasing due to low temperature. Through precise pressure and flow control, combined with intelligent optimization of adsorption time, oxygen with purity that meets the standard can be stably produced regardless of the weather.

Q: For chemical plants with continuous production, the maintenance cycle of equipment is crucial. What is the normal maintenance cycle of the core components of this oxygen production equipment, such as the adsorbent in the adsorption tower, various valves and control systems? During the maintenance process, is it necessary to shut down for a long time? How much impact will this have on our production continuity? Is there a maintenance plan to reduce downtime?

We use the latest developed adsorbents with a normal service life of 8-10 years. During this period, it is recommended to conduct a comprehensive performance test every 1-2 years. The maintenance cycle of various valves is about half a year, and the sealing and opening and closing flexibility need to be checked regularly. The control system is relatively stable, and only software upgrades and hardware inspections are required on a daily basis, and in-depth maintenance is required once every 1-2 years. During maintenance, we adopt a modular design concept, and key components can be replaced online to minimize downtime. For maintenance operations that must be shut down, we will formulate a detailed maintenance plan in advance, cooperate with the production arrangements of the chemical plant, and complete it during production intervals to minimize the impact on production continuity.

Q: Chemical plants are flammable and explosive high-risk places. Oxygen production equipment involves the production and storage of oxygen during operation, and safety risks cannot be ignored. What measures have your equipment taken in terms of safety protection? For example, how to prevent explosion accidents caused by static electricity, sparks, etc., and what specific mechanisms are there for oxygen leak detection and emergency treatment?

Safety is the top priority in our equipment design. The equipment adopts a full metal grounding design to eliminate static electricity hazards; electrical components are all explosion-proof to prevent sparks. In terms of oxygen leak detection, it is equipped with a high-precision oxygen concentration sensor to monitor the oxygen concentration in the environment around the equipment in real time. Once an oxygen leak is detected, the system immediately activates an audible and visual alarm, and automatically closes the relevant valves to cut off the gas source. At the same time, a strong ventilation device is installed to quickly dilute the leaked oxygen to prevent the formation of a dangerous environment.

Q: With the expansion of the production scale of chemical plants or the improvement of production processes, higher requirements may be placed on the production capacity and purity of oxygen production equipment in the future. How flexible is this PSA oxygen production equipment in terms of later upgrades and renovations? Can capacity increase and purity optimization be achieved by adding modules, replacing some components, etc. without replacing the entire set of equipment on a large scale?

This PSA oxygen generator has excellent upgrade flexibility. In terms of capacity improvement, the oxygen production capacity can be linearly increased by adding adsorption tower modules and connecting them in parallel to the existing system. In terms of purity optimization, high-performance adsorbents can be replaced, and the control system software can be upgraded to optimize the adsorption and desorption processes to meet the demand for higher purity oxygen. This modular and scalable design minimizes the cost of subsequent upgrades and can adapt to future developments and changes in chemical plants without the need to replace the entire set of equipment on a large scale.
