Summary0002345: New oil refinery from buildcraft (BC8 / 7.99+)
In buildcraft was changed oil processing system (in BC8 version). Now oil refineries processing to gas and some liquid fuel. On screen some results of oil processing.

So, semifluid generator can take only "raw oil" (not processing), but in config contains lines:
semiFluidOil = 1.0
semiFluidFuel = 1.0
semiFluidBiomass = 1.0
semiFluidBioethanol = 1.0
semiFluidBiogas = 1.0

This lines actual to old version of buildcraft, in new - no one take new fluids.
Please add support for new fluids, thanks!

Found link to system new scheme
fluids have temperature

BuildCraft is still in alpha and so hasn't really worked out the final fuel values for all the different oil variants. When it stabilises a bit more in beta this will definitely be something that will be looked into.

Thanks for answering. But buildcraft with new oil system version of 7.99.0 started at 10-04-2017 (april of 2017 year). Alpha goes so 1 approximately year. So maybe you can add support this request and add to configure values of the oils?

Currently liquids have 3 temperatures: Cold, Hot, Searing. In BC8, only the cold temperature can be used in engines. This forces players to use Heat Exchanger to cool down the liquid. Each cooling/warm has a energy cost in MJ. My suggestion is that we leave the details of balancing between these to BC8 team, and focus only on the cold version of the liquid, that has a direct conversion to MJ in BC8, via their engines. This allow us to look at the values of MJ for the different fluids to set the correct conversion to EU.

The current conversion ratio of a bucket of OIL to EU (the natural occurring oil in BC8 and below) can be our reference point: I will call it EU_PER_OIL, whose unit is [EU/B], B of bucket (this should be somewhere in the IC2 source code).

Taking the reference point of OIL (called crudeOil in BC8), the conversion to EU can be made: for a given fluid X, the EU/B is given by


We only need the values of MJ_PER_X, unit [MJ/B], of each fluid X in BC8. Attached (1) I present their current values and a script to get them. Using the equation above,
we get that the energy (EU/B) that the semifluid generator should generate from each fluid should be given by:

BCEnergyFluids.fuelGaseous = EU_PER_OIL*1/2
BCEnergyFluids.fuelLight = EU_PER_OIL*2
BCEnergyFluids.fuelDense = EU_PER_OIL*4
BCEnergyFluids.fuelMixedLight = EU_PER_OIL*8/10
BCEnergyFluids.fuelMixedHeavy = EU_PER_OIL*8/5
BCEnergyFluids.oilDense = EU_PER_OIL*4
BCEnergyFluids.oilDistilled = EU_PER_OIL
BCEnergyFluids.oilHeavy = EU_PER_OIL*8/3
BCEnergyFluids.crudeOil = EU_PER_OIL



I attached a small Python 3 script that reads the values from the source code of BuildCraft 8.x and prints their MJ/B, so that we can update them as needed.
The current values (cross-validated by an independent calculation [here]( are:

Total power (MJ/B) of each of the BuildCraft fluids:
BCEnergyFluids.fuelGaseous = 15.000
BCEnergyFluids.fuelLight = 60.000
BCEnergyFluids.fuelDense = 120.000
BCEnergyFluids.fuelMixedLight = 24.000
BCEnergyFluids.fuelMixedHeavy = 48.000
BCEnergyFluids.oilDense = 120.000
BCEnergyFluids.oilDistilled = 30.000
BCEnergyFluids.oilHeavy = 80.000
BCEnergyFluids.crudeOil = 30.000 (2,456 bytes)
