I have never heard the expression before, but I have heard of vacuum distilled. It sounds like the distillation was done at greater than atmospheric pressure. I am surprised they labeled it though.
The way a high efficiency distillation process works is that you start with a stage that has high pressure. Then the condensation section is cooled by the boiling chamber of the next stage at a lower pressure. These stages are stacked so each follows the next one, and by the time you get to the last stages you are running a vacuum. That way the same amount of fuel will distill many times as much water as a one stage unit will. Marshall bob smith wrote: > Can anyone tell me what compression distilled water is?
