Rapid voltage fluctuation problem in continuous reforming
Thread Content
During a power outage in continuous reforming, pre-hydrogenation leads to pressure relief; should the reforming section be kept under pressure?
The reforming system can stop feeding material, the recycle hydrogen compressor continues to operate, and the furnace is shut down. Single tower cycle for the stabilizer tower. Drain the steam from the drum.
If there’s a power outage, how can the cyclic hydrogen compressor continue to circulate?
A steam-driven turbine does not stop
Since all the lubrication oil pumps have stopped, it’s impossible for the turbine to still be running
Are all the lubrication pump in your facility electric? A small turbine without steam to drive it
The hydrogen circulation pump in the reformation process uses a turbine
1. Close the on-site valve of the main burner in the heating furnace, and close the on-site permanent light valve according to the specific circumstances. 2. Stop feeding reactants, isolate the recontact system, close the hydrogen outlet valve, and maintain pressure in the reaction system. 3. The steam grid connection valve is disconnected from the grid, and the drain valve in front of the turbine’s quick-shut valve is slightly opened. 4. The distillation system maintains pressure and liquid level.
