Liquid Naphtha

Liquid Naphtha is a high-temperature refined state of Plastic. It is not made through a normal crafting recipe; instead, it is produced by phase transition when Plastic is heated to 162.85°C or higher. If the temperature rises above 541.85°C, it changes into Sour Gas instead, so controlling heat is essential when working with it.

The most common way to obtain it is to heat Plastic in a hot environment until it melts into Liquid Naphtha. If Petroleum is preheated and fed into a Polymer Press, and the Plastic inside the building has already reached the transformation threshold, the Polymer Press will drop Liquid Naphtha instead of Plastic when it finishes its cycle. This makes the building useful as an accidental or controlled source of the material when its internal temperature is high enough.

For small amounts, the simplest method is to build Plastic Tempshift Plates in a hot area. They absorb heat quickly and can transform into Liquid Naphtha with minimal setup. This is the easiest option when only a little is needed for testing, transport, or a one-off conversion.

For larger-scale production, a fully automated setup can be built using a Liquid Tepidizer. Plastic is transported into Crude Oil, and the Liquid Tepidizer heats the Crude Oil so that it in turn heats the Plastic until the phase change occurs. Because Liquid Naphtha is lighter than Crude Oil, it can then be separated from the oil layer. This method is especially useful when Plastic is being converted into Natural Gas in situations where Petroleum is scarce.

Liquid Naphtha can also be used to generate more Liquid Naphtha once a small supply already exists. It may be fed into a Metal Refinery as coolant, then recovered through the heat exchange from the hot coolant output. One method is to place a Plastic Tile in the refinery’s coolant loop and replace the local Liquid Pipe with a Radiant Liquid Pipe, while keeping the area insulated from the surrounding environment. The hot Liquid Naphtha cools down there, transfers heat into the Plastic Tile, melts it, and produces more Liquid Naphtha.

Another method is to place a steel Liquid Tepidizer and a Liquid Pump next to a Plastic Tile, then insulate the whole setup from the outside. Running the Liquid Tepidizer for a while heats the Plastic Tile until it melts into Liquid Naphtha, which can then be pumped out. This approach is straightforward, though Plastic’s low thermal conductivity means it takes a long time to heat through.

• Liquid Naphtha is produced only by heat-induced transformation.
• Plastic converts to Liquid Naphtha at 162.85°C.
• Above 541.85°C, it transforms into Sour Gas instead.
• It can be obtained from overheated Plastic inside a Polymer Press.
• Small amounts are easiest to make with Plastic Tempshift Plates in a hot zone.
• Large-scale production is best done with a controlled heating setup using a Liquid Tepidizer.
• Existing Liquid Naphtha can be reused to melt Plastic and create more of itself.
• Heating Plastic takes time because of its low thermal conductivity.
