  • Use and efficiency of a liquid nitrogen fertilizer on ...

    01-02-1990  The applicability and efficiency of a commercial liquid nitrogen fertilizer (containing 39% N, half urea and half ammonium nitrate) on grassland was investigated in comparison with granulated ammonium nitrate (27% N). The liquid nitrogen fertilizer was applied on continuously grazed paddocks without any repercussions for animal health.

  • Nitrogen: How to increase the efficiency of freezing

    Pressurised liquid nitrogen, with a temperature of -196°C, is sprayed onto the product at high velocity to freeze it immediately. This way, the CWI can extract heat faster. Increasing the nitrogen’s speed is effective: It permeates the food items’ thermal resistance and creates an ice crust around them – locking in natural flavours, nutrients, and moisture.

  • Nitrogen: Increasing the efficiency of food

    As the volume of one kilogramme liquid N 2 is eight times smaller than that of gaseous N 2, it rapidly expands once it hits the hot fluid, supporting the blending process. Once the chilled mixture reaches the cooling kettle, an agitator ensures a smooth heat distribution in the sauce.

  • Nitrogen Use Efficiency and Gaseous Nitrogen

    The nitrogen use efficiency (ANR) varied from 30 to 55% (Table 3). ANR and NFRV were significantly higher at 80% than at 50% water holding capacity (Table 3 ). The lowest ANRs were obtained for incorporated pig slurry (30–39%) and surface-applied MC (33–38%), while the highest ANRs were obtained for liquid NH 4 NO 3 (45–53%) and acidified MC (43–55%).

    performed using nitrogen (typically a flow of 7-15 L/min is required). The required flow can be provided in a number of ways including the use of an in-house generator, the use of pressurized tanks or the evaporation of liquid nitrogen. In recent years, many laboratories have found that the use of an in-house generator is the method of choice to

  • What's the energy density of liquid nitrogen? -

    Their 50 - 80% are cycle efficiency based on "Available enthalpy for cold cycle ~300kJ/kg", so less than half of the energy density they give. Calculating with 1750 kJ/kg to produce the kg liquid air, we're at 17% (close to the "Egyptian" 20% efficiency for producing liquid air), of which they recover 0.5 - 0.8.
