ABSTRACT
Henry's constants of light hydrocarbons in water at low temperature conditions are reported. Due to lack of suitable data for iso-butane solubility in water at low temperature, several experiments were conducted (274 to 293 K). Some modifications on Krichevsky-Kasarnovsky equation have been made to consider the effect of pressure and temperature on the equation parameters. Results show that Henry's constants of the selected components directly depend on temperature, whereas its dependency on the pressure is negligible.
