In the Chemical Extractor deuterium is shown as "liquid.bacterialsludge" but has the correct Name Deuterium when you look at the Fluidduct :/
Probably another bug is that i get to extract Steam from the Steam Funnel. I tried it with every combination with Fluidducts.
The strange thing is, that the Liquidducts show that there is Steam in the pipe but didnt get to fill any type of steam accepting block with it.
