Sour Gas
Sour Gas is an intermediary oil product, that can occasionally be found in the Oil Biome when there is a heat leakage from Volcanic Biome.
Production
Sour gas is produced when 
Petroleum or 
Naphtha is heated to 541.85 °C (vaporization point + 3 °C).
Usage
The only thing that can be done with Sour Gas is to cool it. When cooled to -163.5 °C; 67% of its mass becomes 
Methane and 33% becomes 
Sulfur. If Methane is reheated it becomes 
Natural Gas. Due to the extreme nature of the cooling required, Thermo Aquatuners will require at least 
Super Coolant, so it may be better to ignore Sour Gas until then.
The other options are either: the Anti Entropy Thermo-Nullifier, which still might take some time to reach the target temperature and has to be securely heat-isolated. Or thermo regulators running 
Hydrogen as coolant, though this requires an efficient heat exchanger in order to come out with more power than was required to sufficiently cool the sour gas.
Tips
- Sour Gas serves as the transition route from Petroleum to Natural Gas.
- If Sour Gas at sufficiently low pressure is cooled, 100% of its mass condenses into Methane. The exact pressure necessary for this seems to be around 5 grams or less per tile.
Liquid Oxygen and 
Liquid Hydrogen can theoretically serve as alternatives for Super Coolant.
