Modelling and analysis of condensation processes for low-boiling hydrocarbon mixtures containing hydrogen

The modelling of the condensation of gaseous mixtures containing a non-cond ensing species is discussed. The model selected is applied to the countercu rrent partial condensation of light hydrocarbons (methane, ethylene, ethane and propylene) in the presence of hydrogen. Calculations are performed to study the effect of Hz upon the equilibrium constants of other components, and also, to determine the extent to which the physical solubility of H-2 m ay affect the process. The simulations also demonstrate the sensitivity of the system to certain operating and geometric parameters and show the relat ive importance of these parameters.
