Cryogenic Oxygen Gas Plant

self-cleaning air filters：This filter can be applied to a wide range of air humidity levels. Its cleaning structure adopts a pulse jet type, which ensures reliable operation, low maintenance costs, high filtration efficiency, low resistance loss and low power consumption.

raw air compressors: It is divided into centrifugal compressors and screw compressors, with constant pressure control. It is equipped with measures such as anti-surge operation, automatic pressure control, and impeller vibration alarm interlock.

air pre-cooling units: It adopts imported compressors, which are safe and reliable. It adopts a wraparound refrigerant, which will not leak. By adopting high-quality refrigeration components, the equipment can operate continuously throughout the year and has a long service life. Advanced energy regulators are adopted to ensure that the compressor has no concerns about frequent start-up and shutdown.
It is equipped with a complete alarm interlock protection device to prevent moisture from entering the molecular sieve, making it safer and more reliable.

air purification systems: The design of the molecular sieve purifier adopts a "double-bed" structure, which not only reduces the regeneration temperature and energy consumption but also extends the service life of the molecular sieve. It is equipped with an airflow uniform distribution device, which has a long service life, saves investment and reduces energy consumption.

fractionating column cold box systems:A grounding system for the main cold has been set up to prevent the generation of static electricity. It is equipped with a unique main cooling explosion-proof structure to prevent the accumulation of hydrocarbons on the fins. Select the flow rate of gases containing such substances reasonably, especially that of pressurized oxygen and liquid oxygen, to ensure safety.

turbine expanders: Advanced design and processing software is applied to design and process performance and flow channels, making the efficiency reach the optimal design value and the aerodynamic performance and flow field distribution more reasonable;While ensuring the high efficiency of the expander and the booster, guarantee the matching between the two and the adaptability to variable working conditions;The impeller adopts a three-dimensional flow design and is processed by an advanced CNC milling machine to ensure the processing accuracy of the impeller;Adjustable nozzles are used to adjust the cooling capacity.

instrumentation and electrical control systems: The control mode combining the central control room and the cabinet beside the machine is adopted to effectively monitor the complete set of air separation equipment. The DCS(PLC) instrument control system is adopted to complete the display, alarm and control of the main process parameters. Design and manufacture safely and reliably in accordance with the national and industry standards and norms of China. Beside each unit, a cabinet is set up to enable local operation.
