Calculate the reactor material flow rate
Thread Content
As stated in the title, it is a gas-phase feed; the space velocity is 3 h-1, the feed volume is 200,000 NM3/H, the pressure is 0.3 MPA, and the temperature is 625°C. . . Can the flow rate be calculated, or are there any empirical values for it? Thank you

Reaction space velocity refers to the amount of gas processed per unit volume of catalyst per unit time under specified conditions, measured in m3/(m3 of catalyst·h), and can be simplified to h-1. What is its relationship with porosity?； However, with such a high processing volume and such a low space velocity, the amount of catalyst required seems a bit excessive.
You need to calculate the flow rate, and the unit of velocity is generally m/s. Since you don’t have the cross-sectional area here, how can you calculate it? Air velocity generally includes mass air velocity and volumetric air velocity, referring to the amount of feedstock processed by the catalyst per unit time.
