Hydroprocessing with drum blanketing gas compositional control
A catalytic naphtha hydrodesulfurization process is operated in a process unit having a surge drum with equipped for gas blanketing with a blanketing gas containing controlled levels of CO and CO2. If the gas selected for blanketing normally contains more than the acceptable level of these inhibitor...

Summary: | A catalytic naphtha hydrodesulfurization process is operated in a process unit having a surge drum with equipped for gas blanketing with a blanketing gas containing controlled levels of CO and CO2. If the gas selected for blanketing normally contains more than the acceptable level of these inhibitors, they should be reduced to the levels appropriate for retention of catalyst functionality. |
