摘要

The solubility of i-butane in water at the low temperatures was measured (274 K to 293 K). Additionally, Henry鈥檚 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鈥檚 law constant of the selected components depends on temperature. It is deduced that pressure has a considerable effect on Henry鈥檚 law constant for methane, ethane, and propane, whereas this dependency for butanes is negligible.
