METHOD FOR OBTAINING AN AMMONIUM CARBAMATE SOLUTION FROM A GAS MIXTURE CONTAINING NH3, H2O AND CO2

摘要

The invention relates to a method for obtaining an ammonium carbamate solution from a gas mixture that contains more than 40 wt. % NHSUB3/SUB, less than 50 wt. % COSUB2 /SUBand less than 40 wt. % HSUB2/SUBO and has a pressure between 0.1 MPa and 4 MPa, comprising a compression step, in which the pressure of the gas mixture is increased to a pressure between 0.5 MPa and 25 MPa, and an absorption step.
