Calculation of catalytic lift pipeline velocity
Thread Content
Does increasing the pipeline speed calculation require using volume? How to calculate the equal volume of feedstock in the riser?
To calculate the linear velocity, it is necessary to first convert it to volumetric flow rate. The molar masses at the inlet and outlet of the lift pipe are determined first, and these values are converted into standard volumetric flow rates. Finally, the actual volumetric flow rate is calculated based on temperature and pressure, from which the linear velocities at the inlet and outlet can be determined. By taking the logarithmic average of these inlet and outlet linear velocities, the linear velocity in the lift pipe can be obtained.
Then may I ask how to calculate volumetric flow rate? Is it pv=nrt? Does a catalyst count as volume? Should the volumetric flow rate be counted as part of the product or of the feed?
Volumetric flow rate generally takes into account only the material, without considering the volume occupied by the catalyst. The inlet is based on the volume of the raw materials, while the outlet is based on the volume of the products.
