Coal to Rocket Fuel using Coal Liquefaction, Over-unity Gain!

Post by patrick12222010 » Fri May 17, 2019 12:55 am

I found a blueprint by Pieter van Ginkel, https://factorioprints.com/view/-L-maGtV6rlDNTQ1zQHq
I modified it a bit for 0.17. Here it is:

UPDATE!

Now, I created something a lot bigger. Behold:

Now, for the computations

Still there are people who would want to push coal liquefaction to its limits. See this below post. There is a major discussion also to convert to rocket fuel or not.

So going by kirk's calculation 4.62 rocket fuels means that we first have 33 solid fuel. I'll deal with that math later because it's same with both, but the assembling into rocket fuel means:
Energy cost of 66.2 MW + 8 beacons = 70.04 MW.
How much energy is in rocket fuels: 4.62 * 100 MJ = 462 MJ
33 solid fuels each make 12 MJ so they total 396 MJ.
Difference between rocket fuels and solid fuels is 462 MJ - 396 MJ = 66 MJ.
Now, i'm not perfect with math and physics equations, but we can match MW and MJ right? If it costs over 70 MW to convert it to rocket fuel, the gain of 66 MJ is exceeded. Therefore solid fuel would have been 4.04 MJ more efficient. That's very tiny amount though, about equal to 1 piece of coal. So if you like rocket fuel, sure it still seems worthy investment i guess at least because it's more compressed.

So how much does it cost to produce 33 solid fuels?
20 MW + 1.3 MW + 8.7 MW + 4 MW + (8+8+10+8=34) beacons
= 34 MW + 16.32 MW = 50.32 MW
So reduce the 50.32 MW from (462-70.04) or 396 to get total gain of each fuel.
Rocket fuel: 341.64 MJ (over-unity: 2.84)
Solid fuel: 345.68 MJ (over-unity: 6.87)


Edit: Oops, if you have 18 assemblers and each are affected by 8 beacons, that doesn't mean there are total 8 beacons... More like 38 or 40 maybe? That's going to swing it heavily in favor of solid fuel. mistakes

What do you mean by heavily favor to solid fuel?

I only counted energy cost of 8 beacons, but it appears there are 42. The speed bonus of the all 42 was already count by kirkmcdonald, so that is 34 additional beacons, which means +16.32 MW. We'll replace all number 70.04 MW with 86.36 MW.

Without counting beacons power consumption, the gain of making power with rocket fuel is still 66 MJ.
But with beacons that is now 66 MJ - 86.36 MJ = -20.36 MJ , which is how much less 4.62 rocket fuels make compared to 33 solid fuel.

And i didn't even count beacons used in oil processing in making solid fuel, so i can't even tell the total gains of either fuel. Oh, laying the assemblers and beacons in "double-burger" layout may reduce number of beacons you need, but i'm done testing :P

Looks like spreadsheet is needed... I'll plop this down and compute. ;)

I updated the post and used in game measurements. This should give us more accurate computations.
