DETERMINATION OF THE COMPRESSIBILITY FACTOR FOR SOME HYDROCARBONS BY THE BURNETT METHOD

Unlike other experimental procedures, the Burnett method allows the de termination of the compressibility factor of a real gas from pressure measurements only. The present note deals with compressibility factors obtained with experimental data for some hydrocarbons (ethane, ethene , propane and propene) for pressures up to 50 atm at 25-degrees-C. The experimental values are compared with the calculated ones, using an e quation containing virial coefficients and the Redlich Kowng equation. The obtained values for compressibility factors were used to calculat e the fugacity coefficients.
