Methods and systems for co2 condensation

Abstract

In accordance with one aspect of the present invention, methods of condensing carbon dioxide (CO2) from a CO2 stream are provided. The method includes (i) compressing and cooling the CO2 stream to form a partially cooled CO2 stream, wherein the partially cooled CO2 stream is cooled to a first temperature. The method includes (ii) cooling the partially cooled CO2 stream to a second temperature by magneto-caloric cooling to form a cooled CO2 stream. The method further includes (iii) condensing at least a portion of CO2 in the cooled CO2 stream to form a condensed CO2 stream. Systems for condensing carbon dioxide (CO2) from a CO2 stream are also provided

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to methods and systems for carbon dioxide (CO2) condensation using magneto-caloric cooling. More particularly, the present disclosure relates to methods and systems for CO2 condensation in an intercooled compression and pumping train using magneto-caloric cooling.[0003]2. Discussion of Related Art[0004]Power generating processes that are based on combustion of carbon containing fuel typically produce CO2 as a byproduct. It may be desirable to capture or otherwise separate the CO2 from the gas mixture to prevent the release of CO2 into the environment and / or to utilize CO2 in the power generation process or in other processes. It may be further desirable to liquefy / condense the separated CO2 to facilitate transport and storage of the separated CO2. CO2 compression, liquefaction and pumping trains may be used to liquefy CO2 for desired end-use applications. However, methods for condensation / liquefaction of CO2 may ...
