metal storage tank design
(OP)
I am currently working on a metal storage tank design for Glycol (density a little less than water), and I've seen some previous designs with tanks stiffenend with single angles. Is there any literature out there to figure out the "ring" tension and distribution coeffecients. I'm assuming that the coeffecients in the PCA book on Rectangular Concrete Tanks will not suffice.

If it's round, you could use AWWA D100 or API design specifications. If it's rectangular, you can model it using finite elements or design it by assuming the plates span vertically to the stiffeners and following the loads to the corners. But be prepared for a lot of stiffeners and very thick plates.

Also, take a good look at what, if any, codes this needs to follow, particularly fire codes; whether it needs to be double-walled, etc.
If the tank is small (say, 5,000 gallons or less), it likely isn't worthwhile to do a finite element analysis. Run stiffeners vertically or horizontally, depending on the tank dimensions, treat the plate in between as little beams (or rectangular plates per Roark), transfer that load to the stiffeners, treat part of the wall as the flange of the stiffener. It's very easy to spend $5 of your time saving $2 worth of material on something like this.
Details of rectangular tanks aren't covered by the various codes, so they aren't standardized, and you could have a lot of variation in allowable stress, design assumptions, and detailing.
If you'll be having a fabricator construct the tank for you, they could quite likely design it as well- check and see- but they'd have the same issues to deal with.
