In high-end industrial scenarios such as chemical industry, petrochemicals, pharmaceuticals, food processing, and new energy energy storage raw material storage, the tank nitrogen blanketing protection process has strict and mandatory requirements for nitrogen purity and cleanliness. The core purpose of tank inert protection is to isolate materials in the tank from air contact by continuously inputting high-purity inert nitrogen, eliminating potential safety hazards such as oxidative deterioration, water vapor erosion, and explosion caused by the accumulation of combustible gases. Ordinary nitrogen compressors can only complete gas compression and transportation operations. The nitrogen produced is often mixed with moisture, oil mist and dust impurities, which will not only pollute high-precision materials in the tank, but also cause corrosion of the tank inner wall, pipeline blockage and failure of the blanketing system. As a professional industrial gas equipment supplier, our self-developed and self-produced nitrogen compressor purification system is tailor-made for tank blanketing working conditions. It integrates multi-stage purification, filtration, drying and oil removal technologies, completely solves the problem of excessive impurities in compressed nitrogen, and provides stable, high-purity and clean inert protective gas sources for various industrial storage tanks.

　　Tank blanketing scenarios have highly exclusive requirements for nitrogen purification, which is also a key shortboard of industrial safety production. The gas produced by conventional compressed nitrogen making equipment generally contains impurities such as liquid oil, suspended dust and saturated water vapor. Long-term delivery of such low-purity nitrogen into storage tanks will adhere to the material surface, resulting in reduced purity and quality deterioration. Especially for high-value-added materials such as fine chemical reagents, pharmaceutical intermediates and edible oils, it will cause irreversible quality loss. At the same time, oil and water-containing nitrogen will form scaling and corrosion inside the tank inner wall and pipelines, shorten the service life of equipment, and cause failures of precision components such as pressure sensors and pressure regulating valves, resulting in imbalance of the slight positive pressure environment in the tank and major risks such as air backflow and safety protection failure. Abandoning the traditional simple filtration design, our nitrogen compressor purification system adopts an integrated purification structure to comprehensively purify compressed nitrogen from the source, perfectly adapting to the regular blanketing protection needs of various fixed-roof tanks, atmospheric storage tanks and explosion-proof storage tanks.

　　The complete system adopts a multi-stage progressive purification process to build a full-dimensional gas purification system and ensure long-term high purity and cleanliness of nitrogen. The front end of the system is equipped with a high-precision primary filtration module to intercept large-particle dust and solid impurities in the air and avoid internal wear of the compressor caused by particulate matter. The middle end is equipped with high-efficiency oil removal filter elements and precision oil-water separators to specifically remove liquid oil and suspended oil mist generated during compression, with an oil removal rate of over 99.9%. The rear end is matched with low-temperature freeze drying and adsorption drying modules to deeply remove saturated water vapor in the gas, control the dew point temperature of nitrogen within the industry standard range, and completely eliminate residual water vapor. The nitrogen purified through multi-stage treatment is oil-free, water-free and impurity-free with stable standard purity, which fully meets the clean gas source standards for tank inert protection and adapts to the strict production specifications of pharmaceutical, food and fine chemical industries.

　　Compared with traditional single compression equipment, this special purification system has core advantages of high adaptability, high stability and low operation and maintenance cost. Linked with the nitrogen compressor, the system intelligently matches the gas consumption fluctuation caused by the breathing effect of storage tanks, and can automatically adjust the purification power according to the real-time gas consumption demand of the tank farm. It not only ensures the cleanliness of the gas source, but also effectively reduces equipment energy consumption, achieving remarkable energy-saving effects in long-term operation. The core purification filter elements of the equipment are made of imported high-end filter materials with corrosion resistance and wear resistance, adapting to 24-hour uninterrupted continuous industrial operation. The filter elements have long service life and stable replacement cycle, which greatly reduces the later operation and maintenance costs and shutdown losses of enterprises. Meanwhile, the whole machine is equipped with an intelligent monitoring module, which can monitor core parameters such as nitrogen purity, water content and oil content in real time with visualized data display. It will automatically alarm in case of abnormal parameters, ensuring the all-weather stable operation of the tank blanketing system and eliminating protection blind spots.
