Power Service in a Storage Tank

HGM · May 23, 2006

( Any ideas or guesses would be appreciated to understand this strange and unusual weird chemical phenomen you've uncovered.
: )

I suspect this question was a bit flippen, but.......

I'm really not interested in planting myself in this one... /forums/images/graemlins/blush.gif.... My best guess at the wild deviation of the ingrediants is likely due to the option to reformulate it without changing the MSDS information... I'd be inclined to believe that costs quite a bit.. So, if the company decides it needed to up the hydrocarbons 100%, the could..... Big windows allow for flexability.. The MSDS is primarily to let you know whats in the chemical(generally) and what you would have to wory about with certain exposures.....

Just my guess........BTW, my vote is to add it to the tank not the vessel that you transfer it to.. It stabilizes the entire supply, storage is where the bad stuff happens so nib it in the budd there.. /forums/images/graemlins/grin.gif

Originally MSDSs were developed so local fire and rescue personnel would know what they were dealing with in a fire. Worker safety and right-to-know were then added to the MSDS effort. Unfortunately much of the data in them now is nearly useless. For example here's a constituent of the PS mix...

ORGANIC NITROGEN COMPOUNDS 5 - 40 (%)

This could be trinitrotoluene, or TNT (as in the explosive) or it could be Nylon (as in pantyhose) or anything in between. It really tells us nothing about safety.

( It stabilizes the entire supply, storage is where the bad stuff happens so nib it in the budd there.. )

That's the point here. It does not stabilize the supply, in fact, does the opposite. The material that increases the centane rating makes the fuel less stable and decreases shelf life of the diesel.

I should qualify that statement a bit. The centane enhancers in PS can reduce the thermal stability of the fuel. If you keep your diesel inside it probably doesn't matter. If you keep your diesel in a storage tank sitting in the sun, I think it's a bad idea to add it to the tank in the summer time. It should be fine in the winter time. You are better off using Sta-Bil stabilizer in your outdoor storage tank in the summer. The problem with Sta-Bil is that it costs $50 a gallon (which treats 360 gallons). I think that works out to about twice the cost of PS, right?

Maybe I'm missunderstanding the composition of PS.. It , in my mind, has algaecide and fuel stabilizing features as well as the cetane enhancers.. /forums/images/graemlins/confused.gif.. I do agree that some form of stabilizer needs to be added, but I would recomend against anything that has alcohol in it..

I have a quart bottle of shoe polish and the MSDS lists the same number of ingredients as the Power Service MSDS posted here.

Based on this discovery, plus the fact that the shoe polish even smells just like Power Service, I'll be treating all my diesel fuel with it from now on.... /forums/images/graemlins/grin.gif

Steve is correct though - cetane enhancers should NOT be added to diesel fuel in storage as they increase the degradation of the fuel basestock. Use a biocide or electron quenching agent to help prevent stored fuel from going bad, but don't add a cetane enhancer to it! /forums/images/graemlins/wink.gif
