Containerized Oxygen Generator
ETR can combine all parts of the oxygen generation system into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks and Oxygen Generator. Even the optional oxygen booster and cylinder filling station.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.

Assume that the amount of fertilizer recommended for this plot is 8.5 kg of pure nitrogen, 4.5 kg of phosphorus pentoxide, and 7.5 kg of potassium oxide. If single fertilizer is used, the following results can be obtained: urea 8.546% = 18.5 kg, superphosphate 4.512% = 37.5 kg, and potassium sulfate 7.550% = 15 kg.
If compound fertilizer is used, the amount should be calculated on the formula fertiliser with the least amount of fertilizer recommended, and then the other two kinds of fertilizers should be added. If the content of nitrogen, phosphorus and potassium marked on a compound fertilizer bag is 15:10:15, the compound fertilizer should be applied on the plot: 4.510%=45 kg. In this way, the phosphorus in the soil has already satisfied the nutrient that the crop needs, but nitrogen and potassium can't meet the demand for nutrient of crop and soil. Therefore, it is necessary to add a certain amount of urea and potassium sulfate to supplement. The calculation formula is: (Recommended amount of fertilizer - amount of compound fertilizer) The effective content of the selected chemical fertilizer = the number of additional fertilizer. The plot has been applied with 45 kg of compound fertilizer, which is equivalent to 455% of pure nitrogen in the soil = 6.75 kg, 4.5 kg of phosphorus pentoxide and 6.75 kg of potassium sulfate. According to the requirements of fertilization, 8.5 kg of pure nitrogen and 7.5 kg of potassium oxide on the formula fertilization table, additional application is required: urea (8.5-6.75) 46% = 3.8 kg, potassium sulfate (7.5-6.75) 50% = 1.5 kilogram.
Reasonable fertilizer amount calculation method
At present, all parts of the country are vigorously promoting soil testing and formula fertilization, and the recommended fertilization rates for the soil testing and formula fertilization tables sent by the agricultural technology department to farmers are the amounts of pure nitrogen, phosphorus pentoxide and potassium oxide. However, due to the different effective content of various fertilizers, they should be converted into the amount of selected fertilizers in the actual production process. In general, a relatively simple method is used to calculate the amount of fertilizer. The calculation method is as follows: The recommended amount of fertilizer is the effective content of the selected fertilizer = amount of fertilization.
