Available in PDF, EPUB and Kindle. Book excerpt: Corrosion inhibitors in JP-4 interact with metals such as iron and zinc to form gelatinous precipitates which give rise to filtration difficulties. The problem is minimal in the absence of free water and is more severe in the presence of sea water than distilled water. Anti-icing additive aggravates the filter plugging phenomenon. All seven corrosion inhibitors currently approved for use in JP-4 exhibited filter plugging but some were much worse than others.

Available in PDF, EPUB and Kindle. Book excerpt: Research had been performed by an industry cooperative program determining the effects of various military aviation fuel additives on filtration performance. One of the conclusions of this research was DCI 4A corrosion inhibitor has detrimental effects on water separation performance of fuel-water separators. The objective of this project was to verify previous research's conclusions that DCI 4A corrosion inhibitor caused detrimental water removal effects. API/IP 1581 5th Edition C-model filter-water separators were evaluated using DCI 4A corrosion inhibitor at 15, 10, 5, and 0 mg/L with duplicates at 5 and 0 mg/L. All data supports the conclusion that the lower the DCI 4A corrosion inhibitor concentration, the less impact this additive has on water separation performance. Results with only static dissipater (Stadis 450) and fuel system icing inhibitor (Di-egme) generate on specification data similar to Jet A that contains no additives.

Download or read book Effect of Corrosion Inhibitors on Fuel Behavior in Filter Separator Life Tests written by Robert K. Johnston and published by . This book was released on 1970 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single-element filter-separator tests were conducted to study the effects of fuel corrosion inhibitors on element performance in removing water and solid contaminants from jet fuel. Most of the tests were 'life tests' of 125 hr in which a fuel supply of about 12,000 gal was pumped through the element at 20 gpm in 8-hr cycles, with continuous injection of red iron oxide at a concentration of 0.33 mg/l in the fuel upstream of the test element. This contamination level is typical of fuel encountered by filter-separator elements in field service. The coalescing ability of the test element was checked periodically by injecting water upstream of the element. All corrosion inhibitors that were tested did impair element performance as measured by downstream fuel cleanliness and by element plugging rate, and also gave decreases in the fuel's WSIM (water-separometer rating) and fuel-water interfacial tension. Based on the criteria used in qualifying filter-separator elements under current specifications, most tests indicated element failure. Element failure modes in order of decreasing frequency were coalescence failure, filtration failure, and solids retention failure (plugging). Samples taken at time of transient flow disturbance such as the start of fuel flow or water injection showed increased contaminant levels in the downstream fuel. (Author).

This book was released on 1961 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of corrosion inhibitors on filtration and water separation characteristics of JP-4 fuel was studied in a single-element filter separator test facility, using five types of commercial elements and housings designed to simulate full-scale flow conditions. Standard coarse A/C dust and water were used as test contaminants; a brief study was made using iron oxides. Adverse effects of the corrosion inhibitors varied widely, and the element types differed in efficiency and modes of failure. The CRC water separometer, a bench-scale apparatus, gave a general correlation with the singleelement results. Interaction of additives with fuel constituents caused difficulty in early work, but otherwise the separometer repeatability was satisfactory. Preliminary work on a reference fluid indicated that an "odorless solvent" may be suitable

Download or read book Effects of Corrosion and Anti Icing Inhibitors on the Water Coalescing Characteristics of Military Standard Filter Coalescer Elements written by and published by . This book was released on 1971 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report covers a study of the effects of seven corrosion inhibitors and corrosion/anti-icing inhibitor combinations on the coalescing characteristics of the DOD-type filter coalescer elements used to decontaminate liquid hydrocarbon fuels. The corrosion inhibitors are specified for use in military jet fuels. The report concludes that: The corrosion and corrosion/ anti-icing combination inhibitors did not produce adverse effects on the ability of military standard filter/coalescer elements to remove 1-percent water from JP-5 fuel that had been treated with fuller's earth. The free-water content of the fuel passed through the filter/coalester elements during the 1-percent water injection tests ranged from 0 to 4.4 ppm, which is within specification limits. The WSIM's of the inhibited JP-5 fuel during the tests were between 16 and 88. The low, free-water content did not correlate directly with the relatively low WSIM's. The WSIM cannot be used solely to determine the ability of a military standard filter/coalescer element to decontaminate inhibited JP-5 after it has been treated with fuller's earth. However, the WSIM does give an indication of the ability of a filter/coalescer element to decontaminate uninhibited JP-5.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of fuel corrosion inhibitors on the coalescencing performance of filter-separators were evaluated using a small 1.3 gpm test loop. These tests showed that corrosion inhibitors presently qualified to MIL-I-25017 differed significantly in their deleterious effects on coalescence when tested using Wright-Patterson AFB tap water as the free water contaminant. Single element tests using DOD standard filter-coalescer elements and a 20 gpm test loop showed: (1) filtration performance is affected by the type of solid contaminant used, the type and quantity of corrosion inhibitor, and the brand of filter-coalescer element used; and (2) coalescence performance can be significantly affected by the purity of free water (i.e. dissolved solids) when the fuel contains a corrosion inhibitor and fuel system icing inhibitor.

Available in PDF, EPUB and Kindle. Book excerpt: This report is the result of an investigation to determine the effects of corrosion inhibitors on the conductivity of aviation turbine fuel. Fourteen inhibitors were examined for their effects on JP-4 (and other fuels) with three different anti-static additives. Three of the fourteen corrosion inhibitors significantly decreased the conductivity of the fuel with anti-static additive. Of these three inhibitors, one showed a decrease in conductivity of more than 40% when blended with STADIS 450 anti-static additive. This study resulted in a change of the Qualified Products List (QPL) for corrosion inhibitors. Keywords: Electrical conductivity.

This book was released on 1987 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is an investigation to determine the effects of corrosion inhibitors on the lubricity of different types of fuels. The lubricity level of each fuel sample was measured using the Interav Ball-on-Cylinder Tester. The three most common inhibitors currently used by the Air Force (herein referred to as Corrosion Inhibitors C1, C2 and C3) were tested in petroleum and shale JP-4, JP-8 and isopar with and without other additives present. 'Normalization' procedures were used to evaluate inhibitor effectiveness relative to the wear scar of clay-treated fuels. Other additives were found to have effects on lubricity of fuel with corrosion inhibitor. Temperature variations of 13 degrees C had only a slight effect on fuel lubricity. Keywords: Jet fuel. (JG).
