摘要: A vapor liquid equilibrium model and its related interactive energy parameters based on
UNIQUAC model for the H2O-NH3-CO2 system without solid phase at the conditions of
temperature from 30℃ to 90℃,pressure from 0.1 MPa to 0.4 MPa, and the maximum NH3 mass
fraction up to 0.4 are provided. This model agrees with experimental data well (average
relative error < 1%) and is useful for analysis of industrial urea production.
