Need help with SPOM - can't get 3 kgs oxygen from 4 electrolyzers


Recommended Posts

Hi all, I need help to debug and understand a little problem with my SPOM - I have 2+2 electrolyzers around hydrogen shaft, and 6 pumps at the bottom. I observe constant overpressure message on my electrolyzers, while I have less than 500 g pressure of oxygen at the bottom layer. My atmo sensor for hydrogen is 100 g, and for oxygen is 300 g right now, otherwise I have breaks in oxygen flow. But with 300 g pressure - sure I have oxygen packet size from 600 g up to 1 kg. What am I doing wrong?

Maybe the only unorthodox thing is cooling pipes inside SPOM. I've used to use atmo sensor to control electrolyzers to say over 1.5 kg pressure to stop them, but right now I need max throughput so I decided I don't need one.

Any ideas?

Oh, I found 2 tiles with ~6kg of oxygen right on the top-right tile of 1st and 3rd electrolyzers (where flat hat is), probably that's the reason for overpressure. I have no idea how they stuck there, nor how to avoid them.

It looks like your oxygen zone is a bit tall, usually these designs have the O2 pumps right up against the airflow tiles. I think H2 sensors are usually 250 with O2 at 450.

For future reference, you're probably deleting gasses with this build even if you're still getting 3kg/s out.  The way electrolyzers produce is they alternate emitting hydrogen and oxygen in their upper left tile.  This means they're constantly emitting a different gas than is currently in the cell.  The game will try to merge the existing gas with an adjacent cell of the same element, but if it can't it will delete an equal amount of emitted and previously existing gas.  The solution to this is to keep the electrolyzers right below the 1 tile thick layer of hydrogen at the top of the build.

 

TLDR: You should move your electrolyzers up one tile.
