Abstract (en)

[origin: EP1605198A2] Production of pure liquid carbon dioxide (CO2) at a stable pressure, at a point of use (21) at the end of a feed line (20) involves controlling and stabilizing the pressure of CO2 in a container (10) by controlling the temperature; extracting CO2 from the liquid phase in the container into the feed line; and cooling the feed line under a stabilized pressure to a temperature such that the CO2 temperature at the application point is less than the b.pt. of the CO2 at the stabilized pressure.
