advantages of nh3 Liquefaction System

2020-11-7Results showed that NH3 volatilization and NO3 − leaching are the main hot spots of NF for different crops. For the composition of WF, blue and green WF contributed largely to the total WF of wheat and maize, respectively, and the proportion of gray WF for maize could be decreased by 30% with the reduction in fertilizer amount.

  • Ammonia in refrigeration technology: Benefits and risks

    2021-3-6Ammonia refrigeration system: Strict regulations for machine rooms. Ammonia as a natural refrigerant should not be underestimated, which is why the set-up locations for NH3 chillers must comply with precise regulations. The ground must be sealed, and the room must be gas-tight. Only authorised personnel have access to the set-up location.

    2018-3-1In summary, the Linde cycle would be a good option for direct liquefaction of oxygen. The total efficiency of the system is around 8% (3.3 kW for liquefaction of 2.2 kg/h oxygen – requiring about 250 W). Advantages include a higher temperature of refrigeration and possible system flexibility.Cited by: 5
