High pressure drop in nht reactor
WebThe pressure drop trend should be carefully monitored, especially after a trip incident. In addition, any wetting incident can reduce the strength of catalyst pellets, which could contribute to a high pressure drop. Any inappropriate or inadequate hold-down layer on top can also cause high pressure drop issues. Mass balance across the shift ... WebFor small-diameter reactors, the pressure drop is higher, which increases the volumetric flow rate and reduces the residence time; this lowers conversion. Since heat transfer is more efficient for smaller-diameter reactors because the surface area per volume is larger, the temperature increases less; this also lowers conversion.
