This is an expandable refiner setup for converting 30/s coal into graphite in a 1:1 ratio using refiner special recipes. The refined oil and hydrogen can create a perfect closed loop. 
To start using it, place as many refiners as you'd like, then connect the top and bottom hydrogen and refined oil belts to close the loop. The recipe needs to be primed with fuel in the first fuel producer in the chain (left) and then saturate the entire belt loop with hydrogen. Once saturated, disconnect input hydrogen from the loop. The refiners will then produce refined oil to feed the following refined oil refineries until the x-ray cracking can begin.
