What are the reasons for liquid carryover in the post-dehydrogenation of recycled hydrogen? ? ?
Thread Content
I’m asking everyone for help; I can’t figure it out on my own, so I hope everyone can contribute their ideas
The ones I am aware of are as follows: 1. Excessively high inlet temperature of the high-pressure stream; 2. Excessively high liquid level in the circulating hydrogen desulfurization tower; 3. Excessively high liquid level in the circulating hydrogen liquid separation tank; 4. Solvent foaming; 5. Failure of the foam breaking screens on the tops of the towers and containers
I hope everyone can add more information to see if there are any other reasons that could cause liquid to be carried in the circulating hydrogen
It is also necessary to check whether the heat tracing steam pipeline at the inlet of the circulating hydrogen compressor is in operation
