Abstract
A process and apparatus for hydrotreating a renewable feedstock with improved carbon monoxide management is disclosed. A mixture of renewable feedstock and hydrocarbon feedstock is treated in a hydrotreating reactor to produce a hydrotreated effluent stream and contacting the hydrotreated effluent stream with a water gas shift catalyst bed to produce a shift reactor effluent stream. The shift reactor effluent stream is passed to a cold separator to recover a cold vapor stream and recycling the cold vapor stream having reduced concentration of carbon monoxide to the hydrotreating zone. The subject matter disclosed provides an improved process and apparatus to reduce the accumulation of CO by converting CO present in the hydrotreated effluent stream to CO2 using the water shift gas reaction.
