Designing a Steam Pipe Distrbutor for a Column
Designing a Steam Pipe Distrbutor for a Column
(OP)
Hello all,
Can anyone help me with the design of a Steam Pipe Distributor for an Absorption Column gas inlet.
Gas Specs: 10000 kg/ h of saturated steam (7 bar, 165 C, 3.66 kg/m3).
Any help is appreciated...Thank you.

The sparger could be a straight pipe, or a cross, or a ring - depending on the relative sizes of the sparger pipe and the column. Put the holes along the bottom of the pipe to aid draining.

Thanks for the insight, yeah you are right, then I need to size the main (straight) pipe for steam input into the column.
Could you please tell me, how to calculate it?

Don't forget that in determining the pressure drop through the orifice holes you must allow some pressure drop for the control valve. Also include the liquid head of the submergence of the sparger and the actual pressure in the column. If the pressure across the orifice is more than 50% of the absolute pressure of the steam inside the sparger use only 50% as your design value because the flow will be choked.
Add a bit of a safety margin because in order to keep control the actual flow will at times be above the average flow.

Check out this thread
thread798-188767: Distillation Column Steam Sparger
In my opinion, if the steam is not going into a liquid level, then there is little need for a sparger with sized holes and all. Rather than a "sparger" you just need to break the momentum of the steam to avoid impingement problems.
If sparging steam into a liquid, then consider getting something already available (see example in thread). This "home-made" approach of sizing a sparge pipe is not always that much savings in the long run, and if it has problems then it can cost you far more than the initial savings.
