摘要：

The infinite dilution activity coefficients (gamma(infinity)) of sulfur compounds in hydrocarbons are very important in the reliable design of sulfur removal processes producing cleaner gasoline. We determined 23 gamma(infinity) of sulfur compounds from vapor-liquid equilibrium (VLE) binary systems measurements with recirculation still and 7 infinite dilution activity coefficients of systems containing different sulfur compounds in selected hydrocarbons with comparative ebulliometers. The gamma(infinity) of sulfur compounds in water is very essential for modeling the sour water removal in distillation column. We measured infinite dilution activity coefficient of 4 sulfur compounds in water determined over a range of temperature from 288.15 K to 333.15 K with inert gas stripping method.
