Current issues in reciprocating cycle machines

If the hydrogen-to-nitrogen ratio in the circulating gas is high, how will the current of the circulator change? The technician said it would decrease, but with a high hydrogen-to-nitrogen ratio, the synthesis reaction will deteriorate – won’t the compressor’s power increase then? Seeking help from experts
The high hydrogen-to-nitrogen ratio mentioned by your supervisor is not high enough to cause deterioration in the reactions in the synthesis tower; it might be around 3.2 or 3.1. Compared to a hydrogen-to-nitrogen ratio of 2.8, a higher hydrogen content in the recycle gas results in a lower density of the total gas. As a result, less power is required by the compressor to compress the same amount of gas, and therefore the electricity consumption decreases. This situation is also reflected in hydrogen-nitrogen machines: machines with a high hydrogen-to-nitrogen ratio produce a higher-pitched sound, while those with a low hydrogen-to-nitrogen ratio have a lower-pitched sound and exhibit a slightly higher current level.
