If only the atmospheric pressure section of the atmospheric and vacuum distillation unit is operated, by how much can energy consumption be reduced compared to when both sections are in use?

As the title says. If the comprehensive energy consumption of the atmospheric and vacuum distillation unit when both are in operation is 9.9 kilograms of standard oil, by how much can this consumption be reduced if only the atmospheric distillation unit is used to produce crude residue? Thanks for the advice!
It needs to be calculated based on the actual processing load; electricity consumption will definitely decrease! Vacuum steam can be saved, but without steam generated on-site, the atmospheric tower still requires stripping steam. If the heat exchange network is missing, the final temperature of heat exchange decreases, and the fuel consumption in atmospheric pressure furnaces increases; in atmospheric and vacuum distillation units, fuel accounts for the largest proportion!
The largest share of energy consumption comes from fuel and steam. If production is considered only in terms of the transfer of slag to certain downstream units, this approach is one-sided; there are also intangible benefits that are lost and cannot be quantified
