Jiangsu Tongyue Gas Systems Co., Ltd.,Professional manufacturer of PSA nitrogen generator
PSA is a new gas separation technology, which has been rapidly developed abroad since the late 1960s and early 1970s. Its principle is to separate the gas mixture by using the difference in the "adsorption" performance of molecular sieves for different gas molecules. As a raw material, a high-efficiency, high-selectivity solid adsorbent is used to selectively adsorb nitrogen and oxygen to separate nitrogen and oxygen in the air.
PSA nitrogen generator uses air as raw material, carbon molecular sieve as adsorbent, uses pressure swing adsorption principle, uses carbon molecular sieve to selectively adsorb oxygen and nitrogen to separate nitrogen and oxygen, commonly known as PSA nitrogen. This method is a new nitrogen production technology that developed rapidly in the 1970s. Compared with the traditional nitrogen production method, it has simple process flow, high degree of automation, fast gas production (15~30 minutes), low energy consumption, product purity can be adjusted in a larger range according to user needs, operation and maintenance are convenient, and operation With the characteristics of low cost and strong adaptability of the device, it is quite competitive in nitrogen production equipment below 1000Nm3/h, and is more and more popular with small and medium nitrogen users. PSA nitrogen production has become the first choice for small and medium nitrogen users. method.
With the rapid development of industry, nitrogen has been widely used in the fields of chemical industry, electronics, metallurgy, food, machinery and other fields. my country's demand for nitrogen is increasing at a rate of more than 8% every year. Nitrogen is chemically inactive, and it is very inert under ordinary conditions, and it is not easy to chemically react with other substances. Therefore, nitrogen is widely used as shielding gas and sealing gas in metallurgical industry, electronics industry, and chemical industry. Generally, the purity of shielding gas is 99.99%, and some require high purity nitrogen of 99.998% or more. Liquid nitrogen is a more convenient cold source, and it is more and more commonly used in the food industry, medical industry and animal husbandry for semen storage. In the production of synthetic ammonia in the chemical fertilizer industry, if the raw material gas of synthetic ammonia—hydrogen and nitrogen mixed gas is washed and refined with pure liquid nitrogen, the content of inert gas can be extremely small, and the content of sulfur monoxide and oxygen does not exceed 20 ppm.
Pure nitrogen cannot be drawn directly from nature, and air separation is mainly used. Air separation methods include: cryogenic method, pressure swing adsorption (PSA), membrane separation method.
