METHOD FOR PRODUCING AT LEAST ONE GAS HAVING A LOW CO2 CONTENT AND AT LEAST ONE FLUID HAVING A HIGH CO2 CONTENT

摘要

The invention relates to a method for producing at least one gas having a low CO2 content and one or more fluids having a high CO2 content from a fluid to be treated containing CO2 and at least one compound that is more volatile than CO2, said method implementing at least the following steps: a) cooling said fluid to be treated; and b) separating, at a low temperature, said fluid cooled during step a) into said having a low CO2 content and one or more fluids having a high CO2 content; at least part of the cooling performed in step a) being carried out by exchanging heat with at least one fraction of said gas having low CO2 content in one or more regenerative exchangers.
