Separate components from gases with this desublimator

The Pluto mini-desublimator is used to separate substances in applications such as for tank breathing, thereby reducing emissions to the environment, for recovering raw materials or for protection of downstream vacuum generators. Gas comes in contact with cooled lamellae in the Pluto unit; here, the gas component to be separated desublimates at or below its triple point and adheres to the cold surface in crystalline form. The Pluto unit is split into several sectors to prevent deposits from clogging the gas inlet. As soon as the desublimator is loaded, the solid product is melted off. Separation efficiencies of over 95% are achieved, says the manufacturer. The Pluto unit can be supplied in all weldable materials, and can be used across the temperature range from –20 to 350°C, as well as within a pressure range between vacuum and 10 bars. — GEA Luftkühler GmbH, Bochum, Germany
