At present, the commonly used nitrogen supply methods are: bottled nitrogen transport, liquid nitrogen transport, pipeline transport, cryogenic separation, PSA pressure swing adsorption separation, VPSA vacuum analytical separation, membrane separation.

First, determine the process, first of all, we usually use bottled nitrogen standard bottle volume of about 40L, containing nitrogen and oxygen content of 6nm3, and frequently used users only 4.5-5nm3 actual amount, the rest is not played out, the reason is to let the user supply the manufacturer of gas lamps, each wash bottle, but there is also a certain relationship with the pressure to make, You first need to know the amount of gas you have in the cylinder all day, and then how many hours you use up the gas in the cylinder, if you use 10 bottles of gas, is light for 10 hours, that you have about 1 bottle per hour, the number of bottles in 5 weights. Therefore, the flow rate should be selected 5nm3 / hour,

Second, determine its purity, generally speaking, the gas in the cylinder will be pure, you only need to look at your own will, if there is no concept, you have a partner, or design institute, nitrogen machine manufacturer to consult the specific purity, which depends on the specific use of nitrogen relationship.

At present, several nitrogen methods have their own advantages, but PSA has the highest market share, followed by air separation equipment, and then vacuum pressure swing adsorption nitrogen, which depends on the specific amount and purity, and, if the amount is large, the purity is high (99.99% or more), such as 1000 cubic meters or more, you can choose cryostorage, if it is smaller than this, the purity is low (90% or more). It is recommended to choose PSA pressure swing adsorption nitrogen maker, if the initial degree is low and the flow rate is large, VPSA vacuum analysis can be selected, but the membrane separation is basically no longer used on the market.
