Abstract
A thermodynamic model is presented to calculate N 2 solubility in pure water (273–590 K and 1–600 bar) and aqueous NaCl solutions (273–400 K, 1–600 bar and 0–6 mol kg −1) with or close to experimental accuracy. This model is based on a semi-empirical equation used to calculate gas phase composition of the H 2O–N 2 system and a specific particle interaction theory for liquid phase. With the parameters evaluated from N 2–H 2O–NaCl system and using a simple approach, the model is extended to predict the N 2 solubility in seawater accurately. Liquid phase density of N 2–H 2O–NaCl system at phase equilibrium and the homogenization pressure of fluid inclusions containing N 2–H 2O–NaCl can be calculated from this model. A computer code is developed for this model and can be downloaded from the website: www.geochem-model.org/programs.htm.
