Abstract
The invention relates to a device for separating a flowing medium mixture into at least two fractions, comprising rotating means, means for physically increasing the difference in mass density of the fractions for separating, a feed for medium and a first outlet for discharging one of the fractions of the separated medium mixture. The invention also relates to a method for separating a flowing medium mixture.
Claims5
A method for separating a contaminated gas flow into at least two fractions having different mass densities and removing CO2 and/or H2S contaminants from the gas flow, comprising:
- Supplying a contaminated gas flow mixture for separating;
- Expanding the gas flow mixture to physically increase the difference in mass densities of the fractions to be separated while maintaining a pressure of 10 bars or higher such that at least a portion of the CO2 and/or H2S contaminants in the expanded gas stream become liquefied and the remainder of the gas flow mixture remains in the gas phase;
- Rotating the gas flow mixture in a rotating assembly of feed channels, thereby removing condensed CO2 and/or H2S from the gas flow, wherein the mixture is cooled before the mixture is separated by rotating the gas flow mixture;
- and
- Discharging at least one of the separated fractions.

- Rotating the gas flow mixture in a rotating assembly of feed channels, thereby removing condensed CO2 and/or H2S from the gas flow, wherein the expansion of the gas flow mixture is controlled independently of the rotating of the gas flow mixture;
- and
- Discharging at least one of the separated fractions.
