First of all - awesome mod!
I was looking for a mod where you have to balance liquid byproducts, in this mod you have to balance several processes around the new gases like sour gas and also tar. I like the increased complexity in crude oil processing and it still fits the base game. It will also gives methane another purpose (I'm not there yet but it seems I will get a lot of methane from Cerys).
I am personally not the biggest fan of the possibility for the crafting (with liquid ingredients) to fail, especially for buildings like the foundry. I think that is probably intentional because it was probably designed with Srappy Industry in mind, where all crafting recipes have that possibility, but when you play this without Scrappy Industry it feels a bit inconsistent. So I am thinking a way to turn this feature on and off would be a nice addition. I still like that you have to work with the small amount of heavy oil you get from lubricant for example.
Since this feature also modifies all the crafting recipes from other mods (and I only recently got into modding) I'm not sure if I can change that for myself so easily.
Speaking of other mods, I have found a small incompatibility with AAI Industry. It alters the crafting recipes for oil processing so you don't get any sour gas or butane and without a consistent way to produce sour gas, sulfur processing is difficult.
And another suggestion: since sour gas usually contains significant amounts of hydrogen sulfide and the mod Castra adds hydrogen sulfide vents, I think a way to convert hydrogen sulfide into sour gas or vice versa would be very fitting. Looking into the crafting recipes, maybe even changing the hydrogen sulfide vents to sour gas vents (when both mods are installed) would work and not change the planet too much.
Keep up the great work, I also really enjoy your mod Crushing Industry!
