Pressure Drop in Packed Bed Reactors: ConcepTest and Example Problem
Try to answer this ConcepTest and solve the example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. We suggest that you write down the reasons for your answers. By the end of this module, you should be able to answer these on your own. Answers will be given at the end of this module.
Example Problem 1
A gas flows through a packed bed. Using the properties of the packed bed and of the gas, determine the outlet pressure.
| Packed bed | Feed Gas |
| void fraction = 0.40 | 50 kg/h feed rate |
| particle diameter = 0.5 cm | molecular weight = 55 g/mol |
| inside diameter tube = 5 cm | viscosity = 2.3 x 10-5 kg/m·s |
| length = 30 m | pressure = 12 bar |
| 150°C, isothermal |
