Under what conditions are the air circulation and nitrogen circulation applied in the internal compression process?
In terms of product extraction efficiency, the oxygen and argon extraction rates in the air circulation process are relatively lower. Regarding the energy consumption of the compressors, due to the use of nitrogen as the medium, the energy consumption of the compressors in the nitrogen circulation process is relatively higher. As for general equipment investment, the nitrogen circulation process requires more investment than the air circulation process. In terms of energy consumption, the overall energy consumption of the air circulation process is lower than that of the nitrogen circulation process~~
Thank you for the guidance from the moderator. I also want to know if the choice between air circulation and nitrogen circulation is related to the manufacturing process
Of course, it is related to the subsequent processing steps; the choice of the general process requires thorough evaluation, with factors such as investment, operation, and maintenance all needing to be taken into consideration. Typically, air circulation with a single pump or two pumps is used. In cases where there is a high demand for high-pressure nitrogen, a nitrogen circulation system can be chosen, which eliminates the need for an additional nitrogen compressor and thus saves on investment costs. Additionally, when the specifications and ranges of nitrogen products are quite varied, a nitrogen circulation system is also a viable option~~
It is mainly related to the subsequent production process; generally, more nitrogen is required and higher pressure levels are needed for direct liquefaction, with frequent use of nitrogen circulation
