The solubility of hydrocarbon components in water is of great importance for the environmental sciences. Its prediction is usually based on using the pure component solubilities and the mole fraction of the components in the mixture. The solubility of light alkanes (methane and ethane) in pure water has been studied extensively in past decades. However, due to their extremely low solubilities, it is necessary to predict the aqueous solubility of those components using an accurate method. This article presents a simple-to-use correlation for better prediction of aqueous solubility of light alkanes, where the obtained results of the proposed method have been compared with two activity coefficient models (NRTL and UNIQUAC) and showed good agreements with the observed values.
