Treatment system for treating gases laden with carbon dioxide

Abstract

The present invention relates to a system (1) for processing carbon dioxide-rich gas, comprising a recombining unit (2) supplied with natural gas and discharging carbon dioxide-rich gas, the processing system (1) comprising a drying unit (22), a dihydrogen separation unit (24) and a carbon dioxide capture unit (26) comprising at least one condenser (46), the processing system (1) being configured to cool the condenser (46) using liquefied natural gas, and the processing system (1) comprising a conduit (66) configured to guide liquefied natural gas from the carbon dioxide capture unit (26) to the recombining unit (2). The invention relates to a system (1) for treating gases laden with carbon dioxide, comprising a reforming unit (2) supplied with natural gas and emitting the gases charged with carbon dioxide, the treatment system (1) a drying unit (22), a dihydrogen separation unit (24) and a carbon dioxide capture unit (26) comprising at least one condensation device (46), the treatment system (1) being configured so that the condensation device (46) is cooled using Liquefied natural gas, the treatment system (1) consists of a duct (66) configured to lead the liquefied natural gas from the carbon dioxide capture unit (26) to the reforming unit (2).
