Energy-Efficient PSA Nitrogen Generator
The commonly used methods for nitrogen production include: nitrogen production by cryogenic air separation, nitrogen generator by pressure swing adsorption, nitrogen generator by membrane separation, nitrogen production by cryogenic air separation is a traditional nitrogen production method, it has a history of several decades. The cryogenic air separation equipment for nitrogen production is complex and covers an area that is large, the cost is high and the equipment has a one-time investment, high operating costs, slow gas production (12 to 24 hours), high installation requirements and long cycle times. Comprehensive equipment, installation and infrastructure, etc, below 3,500 Nm3/h, the same scale of investment in PSA nitrogen plants is 20% to 50% lower than that of cryogenic air separation plants. The cryogenic air separation nitrogen plant is more suitable for large-scale industrial nitrogen production, on the other hand, medium and small-scale nitrogen production use pressure swing adsorption nitrogen are more advantageous.
(1) Convenient and quick production of nitrogen: Advanced technology, unique airflow distributor, more uniform air distribution, efficient use of carbon molecular sieves, qualified nitrogen can be provided in about 20 minutes.
(2)Easy to use: The equipment has a compact structure and is completely outfitted. It requires no infrastructure investment and a small investment. It requires only a power supply to connect to the site to produce nitrogen gas.
(3) More economical than other nitrogen supply methods: The PSA process is a simple nitrogen production method. With air as raw material, the energy consumption is only the energy consumed by the air compressor, which has low operating costs, low energy consumption, and high efficiency. advantage.
(4) Mechatronics design realizes automatic operation: the imported PLC controls the fully automatic operation, and the nitrogen flow pressure and pressure are adjustable and displayed continuously to achieve unattended operation.
(5) Wide range of applications: protective gas for metal heat treatment process, gas for chemical industry production, nitrogen filling and purification of various types of storage tanks and pipelines, gas for production of rubber and plastic products, oxygen-free fresh packaging for food industry, and purification of beverage industry And covering gas, nitrogen filling and oxygen-removal of nitrogen-filled packaging and containers in the pharmaceutical industry, protection of electronic components in the electronics industry, and protection of gases in semiconductor production processes. Purity, flow and pressure are stable and adjustable to meet the needs of different customers.
