 Title:
HIGH-PRESSURE TERNARY DIFFUSION IN AN N2-C1-C5 MIXTURE
 
Summary :
ABSTRACT. THIS WORK DESCRIBES A GENERAL PROCEDURE FOR THE DETERMINATION OF FICK’S DIFFUSION COEFFICIENTS ASSOCIATED TO THE EVAPORATION PROCESS IN TERNARY MIXTURES INVOLVING LIGHT HYDROCARBONS AT HIGH PRESSURE. THE NON-IDEALITIES IN THE VAPOR AND LIQUID PHASES THAT NATURALLY ARISE IN THIS SITUATION ARE TAKEN INTO ACCOUNT BY THE APPLICATION OF THERMODYNAMICAL CORRECTIONS TO PERFECT GAS RESULTS. APPLICATION OF THE THEORY IS THEN EXEMPLIFIED FOR THE CASE OF AN C5-C1-N2 MIXTURE AT 101 BAR ABS AND 38.5 C. NUMERICAL RESULTS ARE PRESENTED AND THE APPLICABILITY OF THE PERFECT GAS MODEL TO THIS CASE IS DISCUSSED. KEYWORDS: TERNARY DIFFUSION, POROUS MEDIA, OIL RECOVERING.
