A hydrotreating process is described, comprising the steps of: mixing recycled flash drum oil with nonhydrotreated virgin resid oil in a feed drum; while concurrently heating the nonhydrotreated virgin resid oil with the recycled flash drum oil; feeding the feed oil comprising the nonhydrotreated virgin resid oil and the recycled flash drum oil to a reactor train comprising a series of ebullated bed reactors; conveying a hydrotreating catalyst to the reactor train; injecting feed gases comprising hydrogen and methane into the ebullated bed reactors; ebullating and hydrotreating the feed oil with the feed gases in the presence of the hydrotreating catalyst at a hydrotreating temperature in the ebullated bed reactors to produce an upgraded product stream comprising hydrotreated resid oil and effluent tail gases comprising hydrogen, hydrogen sulfide, ammonia, water, and methane; and separating the product stream in a separator into an overhead stream of gases and oil vapors and a bottom stream of separator oil.
