Short Path Distillation

Short path distillation gets its name from the distance in which the vapor stream is condensed. In this case, the evaporator wall generates the vapors as the feed moves by gravity, while being agitated and distributed evenly, down the evaporator wall. The vapor stream travels a "short path" directly to the condenser which is located within the evaporator chamber. Since the vapor stream is immediated condensed, the short path distillation process precludes the vapor from forming vapor pressure. This allows ultimate pressures of 0.001 mbar to be attained. This also allows heat sensitive materials to undergo purification at much lower temperatures preventing degradation. It also allows for very high ambient equivalent temperatures to be achieved. Short path distillation in a plant setting is a continuous process.
