Sulfur to Plastics is going to be hard to explain though, Factorio not having an in-game encyclopedia...
I got to upgrading my Refinery in my DWM game, and so updated to 0.17.60 in the process :Tricorius wrote: ↑Sun Aug 11, 2019 6:24 am[...]
I build a basic one that just pumps out petroleum. All of my petroleum comes from this early refinery and I just give it more and more oil and burn through the inefficiencies (oil is plentiful so with enough oil—a couple speed moduled oil fields and production moduled basic oil—refineries provide plenty for a decent pre-megabase build...the inefficiency of the basic oil recipe really doesn’t matter when you flood it with an essentially-unlimited resource). In fact, I used to ship crude by rail in my old games, now I refine on site and ship petroleum by rail. (I didn’t check the math, but I believe this means I transport 40% less fluid by letting the refineries void or compress or whatever they do to the unusable portion of the crude.)
The second one (after unlocking advanced oil—which is now necessary to “beeline” if you want to continue expanding your science, let alone construction bots) simply handles everything else and only functions when it needs to. (I don’t even crack down to petroleum anymore.)
