High-pressure series to low-pressure in the hydrogenation unit
Thread Content
Which expert has an emergency plan for connecting the high-pressure section of a hydrogenation unit to its low-pressure section? I’d like to learn from it, thank you!
High liquid level, interface level； Desulfurization system level ； High-pressure pump outlet ； Hydrogen compressor outlet
The reasons for high voltage to cascade to low voltage in these locations are different, so the contingency plans and response methods must also be tailored accordingly
Check the outlet of the feed pump, the cut-off valve of the heating furnace, the outlet of the feed water pump, the high-level level control valve, and the outlet of the high-pressure lean liquid pump
These locations are different, so different handling approaches are required. Moreover, in design, where there is a risk of voltage stacking between high and low pressures, designers typically install check valves, safety valves, or appropriate safety systems. As for operators, in the event of such a situation, they only need to follow the relevant procedures to restore normal operation quickly
