KDN type high purity nitrogen air separation equipment

Cryogenic nitrogen production can not only produce nitrogen but also liquid nitrogen, which satisfies the technological requirements that require liquid nitrogen, and can be stored in a liquid nitrogen storage tank. When there is an intermittent nitrogen load or air separation equipment minor repairs, the liquid nitrogen in the storage tank After entering the vaporizer and being heated, it is fed into the product nitrogen pipeline to satisfy the nitrogen demand of the process equipment. The operation cycle of cryogenic nitrogen production (referring to the interval between two large heatings) is generally more than one year. Therefore, cryogenic nitrogen production is generally not considered for standby. Cryogenic nitrogen production can produce nitrogen with a purity of ≧99.999%. Nitrogen purity is limited by (de dan qi _dan qi chun du shou dao) nitrogen load, the number of trays, tray efficiency and oxygen purity in the liquid air, and the adjustment range is very small. Therefore, for a set of cryogenic nitrogen production equipment, the product purity is basically certain, which is inconvenient to adjust.

The automatic compact liquid nitrogen supply station produces nitrogen from the air, which is liquefied into liquid nitrogen by the nitrogen liquefier and stored in the liquid nitrogen storage tank. The compact structure enables the continuous and convenient supply of liquid nitrogen, and can be used as a small amount of liquid nitrogen supply source in the region. Nitrogen liquefier adopts mixed working medium throttling refrigerators or four-trilling refrigerators as cold sources. The company's series of nitrogen liquefier products can provide customers with more choices, and build small nitrogen liquefaction stations for major laboratories to timely solve the use needs of liquid nitrogen.

Description of all-liquid air separation process Liquid air separation equipment usually refers to air separation equipment that directly produces liquid oxygen and liquid nitrogen products. This type of air separation equipment generally does not produce or produces a small amount of gas products. In order to obtain a large amount of liquid oxygen and liquid nitrogen products, there are roughly two methods at present: one is to first produce gaseous products, and then use liquefaction equipment to liquefy the gaseous products as needed. This method has relatively high energy consumption; the other is The method is to directly use liquid air equipment to produce liquid oxygen and liquid nitrogen products. Compared with the former, this method has lower energy consumption. From the organization of the process, the liquid air separation equipment can be regarded as the conventional gaseous product air separation equipment and liquefaction equipment. The combination of the two, so its process is relatively complicated. In order to reduce the medium consumption of the liquid air separation equipment products, a technical comparison of multiple schemes should be carried out in the organization of the process flow according to the demand conditions put forward by the user.

Oxygen and nitrogen air separation equipment is a set of air separation equipment that simultaneously extracts oxygen and nitrogen from the air. It is a new type of process with a turbo expander. The purified air entering the tower exchanges heat with the reflux gas in the main heat exchanger, is gradually cooled into saturated air, with a small amount of liquefaction, and then enters the lower tower for rectification. Distillation is the process of obtaining pure oxygen and pure nitrogen by partial evaporation and partial condensation in a fractionating tower with different boiling points of oxygen and nitrogen. The role of the lower fractionation tower is to produce liquid air and liquid nitrogen. The function of the main condensing evaporator is to evaporate liquid oxygen and condense gas nitrogen at different pressures under low pressure, and the function of the upper fractionation tower is to obtain product oxygen and nitrogen.
