I have suggested before that with BOP being HO + PG, Sulfur being initially on HO. AOP would add Sulfur from LO and PG liquification making LO from PG.V453000 wrote: ↑Wed Aug 07, 2019 8:06 am The "there are too many things on petroleum gas" point is really dangerous to change - if for example we would put sulfur into heavy oil, it could very easily happen that your refinery would deadlock because you only want to produce batteries/acid, say for mining uranium and laser turrets. Even with AOP and proper automated cracking system, the only solution would be to store your petroleum gas/light oil products somewhere - introducing the same problem as BOP used to have, without a possible proper solution. This can happen right now, too, in a case when you would want to produce a lot/only lubricant, or a lot/only rocket fuel. However both of those cases are quite unlikely and generally don't happen too often, or for too long period of time, as the amount of petroleum gas is pretty much always high.
I'm sorry if I'm missing something, I probably missed/lost some things among the off-topic etc.
This would solve all possible deadlocks letting you convert all products to both LO (meaning Sulfur, Rocket fuel), and to PG for plastic.
This would make everything quite consistent while still adding something to solve at the BOP stage.
