A simple mod to slightly tweak the late game of Industrial Revolution 2. I felt sulfuric acid production was too difficult, especially given the costs of acid-washing to get secondary ores, which are required in great quantities for both Yellow Science & gem production. Refining is also particularly a hassle because you cannot directly generate sulfuric gas, you always get byproducts of petroleum and lubricant.

The aim of this mod is as such:

• Enable refining to petroleum and/or sulfur gas without byproducts to deal with
• Reduce the vast quantity of sulfuric acid required for acid washing setups
• Make gem production less painful while still being a late-game task requiring a significant refining/washing setup

This mod does the following:

• Adds 1:1 lubricant -> petroleum and petroleum -> sulfur gas cracking recipes, unlocked by Advanced Oil Processing tech.
• Reduces the sulfuric acid cost (down to 20 from 60) and slightly increases the secondary ore output (up to 75% from 50% chance) of acid washing recipes
• Gem grinding now always produces 2x powder (up from 1-2 powder)
• Gem production now can produce 1-2 gems (up from 1 gem)
• For good measure, it also adds the Atomic Bomb recipe back to the appropriate tech. Atomic Spidertrons ahoy!

This mod does not itself include any IR content per the IR developer's wishes, it only modifies content set up by the IR mod. It is "balanced" to my personal tastes, feedback is welcome.

Note that if you add this mod to an existing game with Advanced Oil Processing already researched, you'll need to enable the lubricant-petroleum-cracking and petroleum-sulphur-cracking recipes through the console.
