摘要： A method for the separation of liquid CO2 from a 2 phase feed stream, the process comprising the steps of: cooling the feed stream to a cryogenic temperature; expanding the cooled stream so as to further lower the temperature of the feed through expansion; mechanically separating the expanded stream, using a mechanical separator, into a gas phase and a liquid CO2 phase, and; venting the gas phase and outflowing the liquid CO2.
