Large scale commingling of gas

Large scale commingling of gas

Large scale commingling of gas

(OP)
I'm looking at mixing / blending / commingling two different sources of natural gas to give a homogeneous mixture with the 'right' physical composition.

As the commingled stream may not thourougly mix when combined, does anyone know of any equations, rules of thumb, or whatever, for designing for large scale (in this case ~500MMscfd) blending {e.g. are there any equations for calculating length of pipe after mixing if no further downstream mixing event is included.  Should the post mix pipe be coiled, ...).

Any advice is much appreciated.

If you are really worried about weather or not the gas will rapidly mix on it's own maybe you would want to add a static mixer just to make sure.  Maybe just a multi-hole orfice plate would be enough mixing for you.

Here is a link to a website where the static mixer page is not built yet, but I know them, and know that their static mixers (normally for duct sized flow paths) comes from a german guru who is a static mixing expert.

Good suggestion by StoneCold.  Try getting in touch with these folks.

I don't think there's any "rules of thumb" for this type of application, as there are so many variables that must be considered for each application. I agree with the others and recommend the use of a static mixer.

Thanks stonecold, rmw and steamguy2.  For anyone else following this thread, check out www.staticmixers.net - this site had all the information that I required at this stage.
