| Post subject: | Diesel Fuel Additive |
I have a question with regards to diesel fuel additives that contain (and most do) either emulsifiers or demulsifiers. Over the last 12 years no one has been able to adequately answer my question. I have searched, all over. I have posted it here in the past, but no reply, so I will try one last time. Maybe one of you diesel fuel savy fellas might know, since it is not uncommon to use two different additives in the same tank ( what's available). What happens to the moisture in your fuel or tank if you add both an emulsifier and a demulsifier? Serious answers only, please. |

AYMK, water, being denser than Diesel fuel, settles to the bottom of the fuel tank (Edited to be my last and final answer, eh) There are two basic type of Diesel fuel tanks - both types available in at least three flavors: plastic - aluminum - steel - 1st type has no drain or water-separator, like the KJ and Cummins Rams, which are plastic - 2nd type has a bottom drain, as in 18-wheelers, stationary, and storage, and can be with filter\water-separator at or near the tank Water in Diesel fuel is mucho bad for two reasons - water rusts steel, and oxidizes aluminum, with resultant leaks - a nasty bowstidge little bacteria dearly loves Diesel fuel, living at the interface where fuel meets water - - eating, pooping, fornicating makes a nasty slime which clogs up filters and the entire fuel supply system - - worst-case infestation requires complete disassembly to flush\remove the sludge - - infestation symptom: fuel has a nasty sour-ish odor and is slightly brownish-opaque, not clear Very important that your fuel cap functions as shipped from the factory to reduce water in fuel in humid environments Pumped-in fuel from the station is greatest source of water in fuel Water in fuel can be treated in two ways - an emulsifier can be added causing the water to mix with the fuel, which can be pumped to the fuel-manager head which also comprises a water-separator with drain-valve - a demulsifier can be added to separate the fuel\water mix at the tank equipped with a drain-valve - bad thing, both types are alchohol\based, which attracts\bonds with water - good thing, alchohol kills them slimy li'l bowstidges, or at least keeps them inebriated enuff to be removed - a little - emulsifier - mixes water with the fuel, drawing water off the bottom to be pumped out where the tank has no drain-valve - a lot - demulsifier- coalesces the water into droplets which precipitate out of the fuel for drain into the filter\water-separator at the tank - too much alchohol is not good for the Inj Pump, diluting fuel lubricity - the CRD IP's use Diesel fuel as the only lubricant 'Nuther words, both should not be used together - emulsifier is low-ratio alchohol-fuel mix to absorb - demulsifier is hi-ratio mix to precipitate - added together becomes higher-ratio mix, and could transmogrify water into wine, eh......... |
