Lava recipe with calcite is kind of OP on nauvis, it's defeat the purpose to mine iron on nauvis. I suggest to remove or nerf the recipe to balance out the mod. I would choice to remove it, to match the way to use foundry on nauvis on vanilla space age.
For sulfuric that basically OP too, I would suggest lower a LOT what field give or make it finite resource. I would at least reduce the number of sulfuric well (visually it's lot and setup the field is long, vanilla space age have the same problem and I think it's a bit too much fields specially for infinite resource)
Also acid neutralization give a lot of power. It's may be good to remove it or nerf it like in https://mods.factorio.com/mod/Rocs-Hardcore-Demolishers that set temp value to 165 C. Thus that I'm not sure.
Here my though so far for this mod.
