Reactor oil filling issue
Thread Content
Newbie seeking help: In a 100 m3 wax oil hydrogenation reactor, 70 m3 of catalyst has been installed. How much more oil can it hold?
Why calculate this? If necessary, after the catalyst is loaded, there will be a bulk density that can be used for an approximate calculation
30 + 70*porosity + (70 – 70*porosity)*porosity = 30 + 70*(porosity + porosity) – 70*porosity*porosity = the volume of oil that can be stored in the reactor. Porosity is the ratio of the volume of voids within a single catalyst particle to the volume of that particle. It can also be defined as the ratio of the volume of voids between catalyst particles to the total volume of the catalyst. Manufacturers should have these two values; as for porosity itself, it’s somewhat complex, but models can be used to estimate it roughly. Create models at a ratio of 100:1 or 1000:1 based on the actual type and quantity of catalyst used; try to replicate the actual filling method as closely as possible. Then fill the model with oil so that the total volume of oil plus catalyst is 1 m³ or 0.1 m³. By scaling up the volume of oil used in proportion, it becomes possible to determine how much more oil can be stored in the reactor. If the accuracy is not sufficient, multiple sets of models can be created to calculate an average value; it is also possible to determine the void ratio and porosity. Although these two values don’t have much practical significance, they still provide some degree of reference value. This question is also quite boring
