What is an appropriate amount to control for the catalytic pre-heating steam volume?

Reply #22007-12-19

It is generally controlled based on the density of the pre-lift section; a density of 400 kg/m3 is usually sufficient for this section. The specific amount of steam required depends on the volume of material being processed.

When the processing volume remains constant, a higher density in the lifting section allows for an increase in the amount of steam used, which in turn reduces the reaction time and improves the efficiency of catalyst feeding. However, this density should not be too high; it is generally controlled based on the density of the pre-lifting section.
