Petroleum Gas

Petroleum gas is the least common Crude Oil refinery product and only gas product. It has a blue-ish color. It cannot be refined any further.

Obtention
It is mainly obtained via the Oil Refinery. 1,000mb of Crude Oil results in 100mb of petroleum gas.

It can also be obtained by cracking Natural Gas, Bitumen, and Kerosene.

Uses
It can be solidified, but that's a waste.

It is used in producing Overclocked Circuits, Kevlar-Ceramic Compound, Polymer, and Solid Fuel (Rocket Propellant), so value this gas.
