Abstract: Impurities that are less volatile than carbon dioxide, e.g. hydrogen sulfide, are removed from crude carbon dioxide by processes involving distillation of said crude carbon dioxide in a distillation column system operating at super-atmospheric pressure(s) to produce carbon dioxide-enriched overhead vapor and bottoms liquid enriched with said impurities. Where such processes involve a single heat pump cycle, significant savings in power consumption are realized when the distillation column system is re-boiled by at least partially vaporizing liquid in or taken from an intermediate location in the column system.

Abstract: In a method for liquefying a gas rich in carbon dioxide, the gas is compressed to a first pressure greater than its critical pressure in a compressor to form a compressed gas, the compressed gas is cooled through heat exchange with a refrigerant to a variable temperature to form a cooled compressed gas with a density between 370 and 900 kg/m3, the cooled compressed gas is cooled at supercritical pressure in a first heat exchanger to a temperature below the critical temperature, the gas cooled below the critical temperature is expanded to a second pressure between 45 and 60 bara to form a diphasic fluid which is separated in a phase separator to form a liquid and a gas, and a liquid portion originating from the phase separator provides cold to the first heat exchanger.

Abstract: The present disclosure relates to a method of operating a boiler system that includes an oxy-fuel boiler in which an oxygen stream and a fuel stream are combusted to generate a flue gas stream. An air separation unit produces the oxygen stream for the oxy-fuel boiler. A gas processing unit cleans and compresses at least a portion of the flue gas stream generated in the oxy-fuel boiler producing a pressurized carbon dioxide stream. The method includes operating the boiler system, at least for a period of time, in a recirculation mode, during which a carbon dioxide stream from a CO2 compression unit within the gas processing unit is evaporated in the air separation unit and forwarded as a stream to the gas processing unit. The present disclosure further relates to a boiler system for an oxy-fuel process as well as to a power plant comprising such a system. The present disclosure also relates to the use of a carbon dioxide containing stream as a refrigerant.
