    Reduce Pressure of a liquid stream

    Yes it is a distillation column. The column operates just above atmospheric and the stream is 95% water with the balance being oxygenates. We might not be able to use pumps and therefore the 20bar driving force will need to be sufficient to overcome the resistance in the line. However we will...
