Blending is not the same as separating. Each operation requires its own type of equipment.
Adding a distillation step to the P2O machine shouldn't be a big problem. The process is very straight forward. The fuel is already hot coming out of the condensers so there won't be a large heating requirement.
Hmmmm is the fuel is already a gas coming out of the processor perhaps the condensation steps can be redesigned to have the separation happen at that time. I'll do a little research on that.
