Is it better to connect two sets of low-pressure interalcohol units with the same capacity in series or in parallel? !

For the ammonia synthesis system, with two sets of low-pressure intercondenser units of identical design, is it better to operate them in series or in parallel? What are the advantages and disadvantages of each? What are the things to keep in mind when using it in series? I would be extremely grateful if an expert could give me some guidance! :handshake
Place them side by side; even if one has a problem, it can still maintain 50% of its capacity
From an economic perspective, parallel operation is better: 1. Methanol production is higher. 2. The system resistance is low, resulting in less work required from the compressor. 3. It contributes to the stable operation of the system. In terms of gas purity, a series configuration is preferable; after purification through two stages of series-connected alcohol treatment, the levels of CO and CO2 in the gas are much lower than those in a parallel system, which helps to protect the ammonia synthesis catalyst.
They should usually be connected in series for higher gas purification efficiency.
