  In the article correct method for the kinetic Boltzmann equation asymptotic
solution is formulated, the Hilbert's and Enskog's methods are discussed. The
equations system of multicomponent non-equilibrium gas dynamics is derived,
that corresponds to the first order in the approximate (asymptotic) method for
solution of the system of kinetic Boltzmann equations. It is shown, that the
velocity distribution functions of particles, obtained by the proposed method
and by Enskog's method, within Enskog's approach, are equivalent up to the
infinitesimal first order terms of the asymptotic expansion, but, generally
speaking, differ in the next order. Interpretation of turbulent gas flow is
proposed, as stratified on components gas flow, which is described by the
derived equations system of multicomponent non-equilibrium gas dynamics.
