A beginner who is just starting to work with continuous reforming seeks help with some questions
Thread Content
The cycle hydrogen compressor and the booster are connected in series; what should be done if the cycle hydrogen compressor stops suddenly, preventing hydrogen from being delivered to the reaction system? Go to the site to open the flare valve on the top of the separation tank? Will the pressure in the reaction system rise rapidly after a sudden shutdown of the cyclic hydrogen compressor?
Are you referring to the pressure in the reforming reaction or the pressure in the pre-hydrogenation reaction?
The reformed hydrogen is divided into several streams: one stream goes to pre-hydrogenation, while another stream goes to PSA hydrogen purification! High pressure, release low pressure! The hydrogen circulation compressor cannot start; emergency shutdown in effect! What drives the recycled hydrogen?
If the hydrogen generator stops suddenly, it triggers interlocks, causing the feed system and the heating furnace to stop as well
I know that the feed and heating furnace will stop, but will the pressure in the reaction system rise rapidly if the circulation pump stops? We are from UOP; one path goes from the four-way valve to the liquid separation tank and then to the circulator, where it remains in circulation, while another path leads to the liquid separation tank and then to the booster pump. The liquid separation tank before the circulator is not equipped with a flare control valve, whereas the liquid separation tank after the circulator does have such a valve. When the circulation pump stops suddenly and hydrogen cannot be delivered, does the pressure in the reaction system increase? Is it necessary to go to the liquid separation tank in front of the circulator on-site to open the valve and vent?
I heard from the teacher that some systems work in this way: a control valve is installed in the liquid separation tank located ahead of the circulation pump, so that when the circulation pump stops suddenly, there is no need to go to the site to operate the valve.
I heard from the teacher that some systems are designed this way from the start; it’s very inconvenient when the circulation pump stops suddenly. By installing control valves in the liquid separation tank located in front of the circulation pump during maintenance, it becomes unnecessary to go to the site to operate the valves when the pump stops suddenly
We still have two, one thin and one thick
