I will discuss a Boltzmann equation describing Compton scattering and its approximation by the Kompaneets equation. We will see why such approximation may not be correct for particles with energy in the neighborhood of zero and large times. I will then discuss another approximation of the Boltzmann equation at small values of the photon's energy, suggested by Y. B. Zeldovich, and present some results.
