We conduct a study on measuring 
production and on the sensitivity limits at 95% confidence level on thirteen anomalous couplings obtained by dimension-8 operators related to the anomalous quartic couplings. We consider the main 
reaction with the sub-process 
at the Large Hadron electron Collider (LHeC) and the Future Circular Collider-hadron electron (FCC-he). For the LHeC, energies of the 
beams are taken to be 
and 140 GeV and the energy of the p beams is taken to be 
TeV. For the FCC-he, energies of the beams are taken to be and 140 GeV and the energy of the p beams is taken to be 
TeV, respectively. It is interesting to note that the LHeC and the FCC-he will lead to model-independent limits on the anomalous quartic couplings which are one order of magnitude more stringent than the CMS Collaboration limits and are competitive with other limits reported in the literature.
