Design pressure of biogas reactor
Thread Content
1 An anaerobic reactor with a diameter of 16 m and a height of 20 m, featuring a biogas pressure of 3 kPa at the top and a water level of 19 m. What should be the appropriate design pressure for this reactor? 2 For containers of the same size with an open top and a liquid level of 19 m, should the design pressure be based on atmospheric pressure or on the static pressure corresponding to 19 m?
The design pressure does not take water level into account, while the calculated pressure does.
For a liquid level of 19 meters, it is recommended to take the static pressure into consideration.
Operating pressure, design pressure, calculated pressure. The three concepts are different.
