This compact blueprint uses a 0-spaced fractionator setup with 100% efficiency. Unfortunately, power poles cannot move in between the fractionators, so it is a little wider than I hoped (50x110 tiles). Spacewise, it is probably more convenient to remove 4 fractionators to place a satellite, but I find this more pretty. A single ILS may not have enough throughput, so you may need to help it with additional ILS and drones.

Produces: 36k/m deuterium
Consumes: 36k/m hydrogen, 1k/m proliferator mk3
Power: 2.5 GW (not including logistics)

Blueprint shenanigans:
- The 0-spaced fractionator can be made by manipulating the belt dot going out of the fractionator. See this blueprint for more examples of this and an explanation.
- The hydrogen line is replenished using simple telesorters
