I couldn't remember the name, but Mr. Art's idea of "defraction tower" 
sounds about right. It is basically a big condensing still capable of 
fractional distillation in large quantities. But I think you got it 
backwards, as the crude rises(in vapor form) it cools and the lighter 
components condense out. Heavy oils and tars at the bottom, and lighter 
oils, gasoline, etc toward the top.
