Six cylinders of nitrogen (40 liters each, 12 MPa pressure, 99.99% purity) purchased from external suppliers are required for this purpose. Now I want to generate the nitrogen myself using a nitrogen generator – what size generator do I need? For the entire set of equipment (including air compression and purification systems, oxygen-nitrogen separation systems, etc.), that is, something which can be installed and used for introducing nitrogen right away, how much would it cost approximately? What are the operating costs?
Your dosage is too small; I don’t think it’s cost-effective.
Is the nitrogen generator produced on demand? Could it be produced in advance and stored for use later?
0.04*120*6/60=0.48 NM3/min; 2 NM3/min should be sufficient, and a storage tank can also be added
The price isn’t very high, but the flow rate is low; it’s better to use bottled gas in that case
A configuration using a low-temperature storage tank along with an air-temperature vaporizer can be used; the cost will definitely be lower than that of gas cylinders, but there will be an additional cost associated with renting the storage tank~~
Tens of thousands of yuan; please consult the manufacturer for specific details. There are many PSA manufacturers.
5 cubic meters; the nitrogen generator costs around 20,000 yuan.
The current liquid nitrogen market is in a poor state~~ Using liquid nitrogen can be a good option; generally, the pressure in medium-pressure storage tanks is below 2.5 MPa, so it’s necessary to determine whether this is suitable for your own manufacturing process~~
Using liquid nitrogen is the most convenient and cost-effective option.

What is the cost-performance ratio of the P860-3N nitrogen analyzer from Shanghai Changai Electronic Technology Co., Ltd. and the JY-160E nitrogen analyzer from Jiuyin Technology Development (Shanghai) Co., Ltd.? The instruction manual for the nitrogen generator I purchased specifies P860-3N, while the device that was sent uses JY-160E. I’m not sure why As a beginner, consult experienced practitioners first before getting in touch with the manufacturer, so as to avoid being deceived by them.
