  The density of a moderately dense gas evolving in a vacuum is given by the
solution of an Enskog equation. Recently we have constructed in [ARS17] the
stochastic process that corresponds to the Enskog equation under suitable
conditions. The Enskog process is identified as the solution of a McKean-Vlasov
equation driven by a Poisson random measure. In this work, we continue the
study for a wider class of collision kernels that includes hard and soft
potentials. Based on a suitable particle approximation of binary collisions,
the existence of an Enskog process is established.
