VERFAHREN ZUM ABTRENNEN SCHWERER KOMPONENTEN AUS VERFLUESSIGTEN GASEN

For separating a higher boiling component from a liquefied gas, e.g., CO, rectification is used wherein a partial stream of the liquefied gas is vaporized, superheated, and then fed into the lower portion of a rectification column. The remainder of the liquefied gas in the liquid phase is fed into t...

Zusammenfassung:	For separating a higher boiling component from a liquefied gas, e.g., CO, rectification is used wherein a partial stream of the liquefied gas is vaporized, superheated, and then fed into the lower portion of a rectification column. The remainder of the liquefied gas in the liquid phase is fed into the upper portion of the rectification column. The rectification results in the higher boiling component being concentrated in the bottoms, and the overhead gas product being purified thereby. Additional purification is possible by liquefying and refluxing part of the overhead gas product, and in this case, it is possible to superheat the entire liquefied gas so as to obtain ultra high purity product.
