Problems of pressure fluctuations and hydrogen mixing amount fluctuations in the reforming unit
Thread Content
:In L fixed-bed reforming, the hydrogen mixing ratio often fluctuates significantly; sometimes these fluctuations can reach 2,000 cubic meters, and generally it tends to increase. Upon observation, it was found that large and rapid fluctuations in high pressure were the cause of fluctuations in the hydrogen mixture ratio, but the source of those pressure fluctuations could not be identified. . . It’s really frustrating when this happens under normal conditions with proper feed rates, temperature, pressure, etc...
Dear, when the plant is shut down, check the demister screen of the high-pressure tank – it might be clogged. Also, check whether there are any issues with the compressor’s pressure control, such as problems with the instruments or the logic involved. I hope this helps; thank you
