In the article, correct method for the kinetic Boltzmann equation asymptotic solution is formulated, the Hilbert method and the Enskog error are considered. The equations system of multi-component nonequilibrium gas-dynamics is derived, that corresponds to the first order in the approximate method for solution of the kinetic Boltzmann equation within the Struminskii approach. It is shown, that velocity distribution functions, received by the proposed method and by the Enskog method within the Enskog approach to solving of kinetic Boltzmann equation for gas mixture, are equivalent to first infinitesimal order terms, but, generally speaking, differ in the next order. An interpretation of turbulent gas flow is proposed, as stratified to components gas flow, which is described by the derived equations system of multi-component nonequilibrium gas-dynamics.
