摘要：

The expression for driving force is presented for multicomponent gas hydrate nucleation in an aqueous phase. The derivation includes working equations for predicting the composition of a hydrate nucleus. The results for driving force in multicomponent systems show a significant effect of the composition of the hydrate nucleus. All past work assume a fixed composition based on the three-phase equilibrium point independent of subcooling and supersaturation. (C) 2004 American Institute of Physics.
