The solubility of i-butane in water at the low temperatures was measured (274 K to 293 K). Additionally, Henry%26apos;s law constants of light hydrocarbons (methane, ethane, propane, i-butane, and n-butane) in water at the low temperatures are reported. A modified equation based on Krichevsky-Kasarnovsky equation is proposed to consider the effect of pressure and temperature on the equation parameters. Results show that Henry%26apos;s law constant of the selected components depends on temperature. It is deduced that pressure has a considerable effect on Henry%26apos;s law constant for methane, ethane, and propane, whereas this dependency for butanes is negligible.
