Gas flow rate issue

This post was last edited by zhenghuacn on 2009-10-27 at 10:11. I currently have an oil-water separator with a gas flow rate of 32,000 cubic meters per hour, a design pressure of 6.3 MPa, and gas inlets and outlets of DN250. I would like to ask everyone what the most appropriate diameter for this equipment should be; I chose DN1800. Additionally, a wire mesh demister should be installed at the gas outlet. As for the diameter to choose, I selected DN1000 – I’m not sure if this is appropriate
Calculated at a gas flow rate of 30 m/s, the diameter of the heat exchanger is less than 700; how did you get a value of 1800? ? It seems reasonable to have a larger head, but the wire mesh demister also doesn’t take up much space. Think about it, or tell me how you calculated it. If there are any issues, let’s discuss them together.
The oil-water separator needs to take residence time into consideration
It’s on the second floor; it’s not a heat exchanger, but an oil-water separator
I don’t understand what the original poster means by oil-water separation――is it the separation of oil, water, and gas, or the separation of oil and gas? If it’s for oil-water separation, how can there still be a gas channel? Also, if it is oil and gas separation, what is the temperature of your gas? What is the composition of this gas? Dry air? Notes: 1. The calculated value for the second floor is incorrect; pressure was ignored in the calculations. 2. What is commonly referred to as oil-water separation is actually static separation. Could the original poster provide more detailed information on this? I can calculate the result only after understanding it clearly~
The calculation requires knowledge of the gas density or gas composition; otherwise, it cannot be performed.

The original poster should clarify the temperature conditions of the process, the amount of oil and water present in the gas, as well as the design structure of the equipment; otherwise, it will be difficult for others to provide meaningful suggestions. It would be best to include a schematic diagram to illustrate these details.
