METHOD FOR OBTAINING 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 %.NH₃, LESS THAN 50 WT.% O₂ AND LESS THAN 40 WT.% H₂O 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.(FIG 2)
