Sorry, my bad. There was an error in a program I wrote to get information from the website. I didn't even consider the "processed by" category and hence it was putting it in the wrong place. Sorry for the inconvenience.

On the steam wiki page: https://wiki.factorio.com/steam, there is an error in the far right information box.
Steam is listed as being produced by Oil refinery when in fact it is consumed by it. A very small error, but I would like to address it for correctness.
