How are the inlet and outlet diameters of the absorbent fluid in a packed tower determined?
Thread Content
Dear sea friends, how is the diameter of the inlet and outlet pipes for the absorbent liquid in a packed tower determined? What’s the general idea? I hope some friends who know can help clarify it?
The diameter of the inlet and outlet pipes is determined based on the processing capacity of the packed tower; the outlet pipe can be appropriately larger in diameter than the inlet pipe
So if the inlet and outlet flow rates are known now, how should the flow velocity be determined? Is it by using an empirical value for the flow velocity? Can the inlet flow rate be determined based on the pump selection? How should the outlet flow rate be determined?
The flow rate of the pump is determined based on the processing capacity, while the pipe diameter determines the flow velocity. Once the pump is selected (taking factors such as flow rate, head, and lift into account), the diameter of the connecting pipes is also determined
First, it’s necessary to see what is connected to the outlet pipe. Extracting pumps and transfer pumps, or tank heat exchangers, etc. It’s simple to select a pump – just calculate based on the pump’s parameters. If it is a transfer pump, check the residence time in the tower bottom, calculate the liquid level height accordingly, and then determine the natural flow velocity v of that liquid level using v=√(2gh). A coefficient is determined based on the viscosity, and this coefficient is then multiplied by v. It’s the pipeline flow rate. The pipe diameter can then be calculated. If it goes directly into the tank or heat exchanger, the distance must be very short; it’s sufficient to use a pipe diameter that is slightly larger than that of the inlet pipe.
