Calculated according to the nitrogen production project 50Nm3/h， nitrogen purity 99.99% use requirements

1、The running cost of bottle nitrogen

   Generally， the price of 99.99% purity nitrogen in the market is 40 RMB/bottle， and the standard volume of a bottle of nitrogen under 12Mpa pressure is 40 liters， which is actually only about 5M3 per bottle， so the price is about 8 RMB per cubic meter of common nitrogen. This kind of gas consumption is only applicable to users with very small gas consumption.

2、The operating cost of liquid nitrogen

    The price of 99.99% liquid nitrogen in the market is 1350 yuan/ton， and one ton of liquid nitrogen can be vaporized to get 840 cubic meters of gaseous nitrogen， and the price per cubic meter of nitrogen is about 1.588 yuan. (Excluding the cost of liquid nitrogen storage tank， vaporizer， annual maintenance and labor)

Cost of using liquid nitrogen: 50Nm3/h×1.6 RMB=80RMB/hour

Annual use cost: 80×8000 hours/year=640，000 yuan/year

3、Operating cost of on-site nitrogen production (calculated on the basis of 50Nm3/h of your nitrogen production project)

The running cost of the system is mainly composed of the following aspects.

    1、Consumption of electric energy

    2、Labor

    3、Equipment maintenance cost

    4、Depreciation of equipment

 Electricity consumption is mainly from the following aspects.

 Air compressor: The rated power of the air compressor is 37kw， because the unloading of the air compressor and the appropriate amount of compressed air are taken into account when the system is selected， so the actual power consumption of the air compressor is about 80% of the rated power， that is: about 30kw.

Freeze dryer: The rated power of the freeze dryer is 1.5kw.

Nitrogen generator: The raw material of nitrogen generator is compressed air， and the nitrogen generator itself basically does not consume electricity， and its main power is for instrumentation， and the rated power is about 0.6kw.

Comprehensive above， the power of the whole nitrogen system is 32kw.

Assuming that the electricity cost is 0.7 yuan/kwh， then the electricity consumption is 32×0.7=22 yuan per hour.

The converted electricity consumption per cubic meter of finished nitrogen: 22÷50=0.44 yuan

Use cost: 50Nm3/h×0.44RMB=22RMB/hour (electricity cost)

Annual use cost: 22×8000 hours/year=176，000 yuan/year (electricity cost)

Labor cost: Because the equipment does not need to be manned， only regular and irregular inspections are required， so the set of gas production equipment in the calculation of operating costs， labor costs can be calculated in accordance with 50 yuan per day.

Equipment maintenance and upkeep costs.

The maintenance and upkeep costs of the whole machine are mainly reflected in

Air compressor

Air filter element: replaced every 4000 hours Unit price: 800 yuan/only

Oil and gas filter cartridge: replaced every 8，000 hours Unit price: 800 yuan/only

Oil filter cartridge: replaced every 2000 hours Unit price: 800 yuan/only

Lubricating oil: replaced every 2000 hours Unit price: 800 yuan / time

Compressed air filter C， T， A three-stage filtration   

    Every 4000 hours to replace: 1800 / 3   

Nitrogen machine: oxygen analyzer probe: every two years to replace the unit price: 580 yuan / only

Nitrogen press: the whole equipment does not need to replace parts only the stability of the components must be checked frequently.

Depreciation cost of equipment: the depreciation period of equipment ten years

4， nitrogen machine PD4N-50Nm3 / h complete set of total investment of 360，000 yuan (including screw air compressor system)

  1， the cost of using liquid nitrogen.

  The cost of using liquid nitrogen: 50Nm3/h×1. 6 yuan/cube=80 yuan/hour

  Annual use cost: 80×8000 hours/year=640，000 yuan/year

2. Cost of nitrogen production system.

   Electricity + labor + equipment maintenance + depreciation of equipment

   Annual usage cost: 110，000 yuan/year (electricity) + 18，000 yuan/year (labor) + 5580 yuan/year (maintenance) + 36，000 yuan/year (depreciation) = 169，580，000 yuan/year usage cost

3、The annual cost of using nitrogen in cylinders.

   The cost of using liquid nitrogen: 50Nm3/h×8 yuan/cube=400 yuan/hour

   Annual use cost: 400 × 8000 hours / year = 3.2 million yuan / year

4. Annual cost of using cylinder nitrogen: 3.2 million yuan/year

   Annual use of liquid nitrogen fee: 640，000 yuan/year

   Annual use of nitrogen machine cost: 169，580，000 yuan/year

Advantages of owning a field nitrogen generator (nitrogen generator):

Before using the nitrogen generation system on site, many enterprises in the industry have no choice but to buy nitrogen elsewhere. However, the use of on-site nitrogen generator can eliminate all the troubles related to bulk purchase of nitrogen. Our nitrogen generator is an option with the greatest benefit: the average cost of producing nitrogen by ourselves is one-third to one-half lower than the relevant cost of purchasing nitrogen. Using the on-site nitrogen generator system, there is no need to pay the freight when purchasing nitrogen. Our nitrogen generator system usually allows you to recover the cost within 18 months.

In addition to economy, the nitrogen generator system of the on-site nitrogen generator also provides:

Reliability - the nitrogen generator system, that is, the on-site nitrogen generator system, uses the surrounding air to generate nitrogen. Therefore, our customers never have to worry about the shortage of nitrogen. Reduce stress - improve safety through storage. Simple - we make it easy for people without relevant equipment experience. The visual touch screen control can control the stability of gas purity. At the same time, it can operate self diagnosis, visual operation diagram and maintenance plan reminder on the screen. Flexibility - our equipment is small and can be transported under various conditions, so as long as there is air and electricity, the equipment can operate stably anywhere. Fully automatic - once a downstream request is detected, production begins.

Why use XITE nitrogen generator?   Our nitrogen generator system provides reliable on-site nitrogen supply for various industries, which is famous in China and Southeast Asia. Our on-site nitrogen system can produce nitrogen with purity up to 99.999%. For our nitrogen generator, it can meet the nitrogen production in any place and any complex environment.
