The effect of impurities on a superconductor with Bogoliubov Fermi surfaces(BFSs) is studied using a realistic tight-binding model. Based on the bandstructure composed of $d$-orbitals in tetragonal FeSe, whose S-doped sample isa potential material for BFS, we construct the superconducting state byintroducing a time-reversal broken pair potential in terms of the band index.We further consider the effect of impurities on the BFS, where the impuritypotential is defined as a local potential for the original $d$-orbitals. Theself-energy is calculated using the (self-consistent) Born approximation, whichshows an enhancement of the single-particle spectral weight on the Fermisurface. This is consistent with the previous phenomenological theory and isjustified by the present more detailed calculation based on the FeSe-basedmaterial.
