... Abstract. A formula for the calculation of equilibrium constants of paraffins in a paraffinic medium has been given by van Wijk and Geerlings. The formula is particularly suitable for a digital computer. It is valid in the pressure range 0.8-5 atmospheres and in the temperature range 0-350 o C...
