Solid fuel from petroleum gas

Solid fuel from Petroleum gas is a recipe that converts Petroleum gas into Solid fuel using a Chemical plant and the appropriate recipe. Solid fuel can be produced from any of the three refinery products—Heavy oil, Light oil, and Petroleum gas—giving players flexibility in how they use excess petroleum products. The different feedstocks produce Solid fuel at different efficiencies; Light oil provides the best direct conversion rate among the three, while Heavy oil’s effective yield changes if it is first cracked into Light oil.

Practical notes and production considerations:

• Feedstock options: Heavy oil, Light oil, and Petroleum gas are all valid inputs for Solid fuel production. Use the feedstock that is most abundant or least valuable to your factory.
• Relative yields: Light oil offers the most favorable generation rate for Solid fuel (described as a 10:1 generation rate in available documentation). Heavy oil’s yield is affected if you use oil cracking to convert some Heavy oil into Light oil: Heavy oil’s conversion behavior changes from a 20:1 context to an effective 13:1 when cracking is applied. Specific numeric yields for Petroleum gas are not listed in the referenced sources; treat Petroleum gas as a viable but context-dependent feedstock.
• Energy value and use cases: Solid fuel provides significantly more heat per unit than raw coal (sources note it supplies more than three times the thermal energy of coal). Despite the higher energy density, using Solid fuel as a primary power source requires substantially more infrastructure than mining coal. Producing Solid fuel requires oil extraction and refining infrastructure, including Refineries and Chemical plants, and may involve oil cracking setups to balance product flows.
• When to prefer Solid fuel: Choose Solid fuel when your map has abundant petroleum resources and limited coal, or when you need to turn excess petroleum products into a compact, high-energy fuel or chemical feedstock. Avoid relying on Solid fuel as the main fuel source if coal is plentiful and oil is scarce, because a single burner-miner can supply coal cheaply while Solid fuel production consumes refinery and chemical production capacity.
• Factory design tips: Route lower-value petroleum products to Solid fuel production to avoid wasting resources. If you have excess Light oil, prioritize direct Solid fuel conversion for best efficiency. If your refinery output is Heavy oil-heavy, consider cracking to Light oil before making Solid fuel to improve overall yield, balancing the cost of additional chemical plants and the benefits from improved conversion rates.

Solid fuel from Petroleum gas is a useful sink for surplus petroleum products and a compact, high-energy fuel option when your factory’s resource distribution and infrastructure support oil-based processing.
