ABSTRACT:
Resid hydrotreating conversion of resid can be substantially increased by decreasing the feed gas rate and simultaneously increasing the concentration of hydrogen in the feed gases. Hydrogen purity can be increased by increasing the flow rate of lean sponge oil into the sponge oil absorbers, bleeding some of the recycled reactor tail gases, and increasing the makeup gas rate.
