When buying liquid nitrogen from companies like Airproduct, and taking into account the costs of equipment and operation, what is the cost per Nm3 in terms of currency? ! Will it be much cheaper than bottled nitrogen?
The company enters into a lease agreement with its branch office; the manufacturer provides the liquid nitrogen tanks, while the company guarantees a minimum monthly usage level. When it’s cheap, the price is 500-600 per ton. The ideal amount to use per batch is 800 cubic meters, and the cost is a little over one yuan per standard cubic meter. It is said that demand from steel mills has increased nowadays, leading to higher prices for air separation gases; the price of liquid nitrogen could reach 1,000. Bottled nitrogen is available in bottles of 6 cubic feet each, at a price of around 30 yuan; for smaller quantities, the cost increases due to shipping and labor expenses
The original poster isn’t majoring in chemistry, right? How could nitrogen be more expensive than ammonia? Nitrogen is separated from the air, whereas ammonia needs to be synthesized chemically. The cost of ammonia is no less than 3,000 yuan per shipment.
The brother is really professional. Nitrogen isn’t cheap at all. What is the typical purity of liquid nitrogen? 99.99%?
With the correct method, there are virtually no problems at 99.999%, provided that the liquid nitrogen is thoroughly filled in before use and that the pipes used are clean and leak-free. The moisture standard is
It will definitely be much cheaper than bottled nitrogen.
These days, the purity of liquid nitrogen is above four 9s, and tank trucks are definitely cheaper than bottled versions.
The poster is only referring to liquid nitrogen, not highly pure nitrogen; therefore, the purity should not be that high. Currently, the price of liquid nitrogen is generally between 600 and 1,000 yuan per ton; the midpoint value of 800 yuan per ton can be used. One ton of liquid nitrogen equals 800 cubic liters, so one cubic liter of nitrogen costs around one yuan.
