Available in PDF, EPUB and Kindle. Book excerpt: Microorganism growth during hydrocarbon storage is a well-recognized problem. The most easily detected problem is fuel filter plugging, particularly in aviation fuels. Other problems include degradation of hydrocarbon quality, corrosion of storage tanks, and concentration of hazardous or toxic growth by-products in the water associated with the storage.

This book was released on 2003-03-01 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Military aviation fuel systems can be an ideal environment for microorganisms. Microbial growth in hydrocarbon fuel systems arises because of the impracticality of keeping fuel tanks sterile and the inevitable presence of water from condensation. Microbial contaminants in aviation fuel systems are a concern because of their potential to degrade the fuel, accelerate tank corrosion, and threaten flight safety. This research addresses the concern of using more environmentally friendly Fuel System Icing Inhibitors (FSII), which are also biocidal. Are significant levels of microorganisms growing in military aviation fuel systems, and if so, are there any common variables? Forty aviation fuel samples were collected from fuel storage tanks (including flexible expeditionary fuel bladders), refueling trucks, and aircraft from 12 U,S, military bases. Samples were analyzed using peak naming and pattern recognition algorithms of sample extracts processed on a gas chromatograph. Significant levels of microorganisms were found in military aviation fuel systems 90% (36 of 40) of fuel samples produced microbial growth. Over 40% of the serial dilutions that produced microbial growth were characterized as moderately or heavily contaminated samples. The microorganisms isolated were overwhelmingly Gram negative, anaerobic, bacilli with populations varying by orders of magnitude.

Available in PDF, EPUB and Kindle. Book excerpt: A study was undertaken to develop information and methods for control of microbial growth in jet fuel storage tanks and aircraft wing tanks, and to determine the vulnerability of other widely used AF materials to microbiological attack. The relative contamination level of fuel storage tank bottoms at 30 AF bases was determined, the flora characterized, and pathogenicity to laboratory animals of the predominant types determined. A number of water-soluble microbicides were evaluated. Potassium dichromate was an effective biostatic agent in laboratory and limited-scale field trials. A number of fuel- and watersoluble biocides were evaluated and several selected as worthy of more intensive testing. Ethylene glycol monomethyl ether, the principal ingredcient of mil-i-27686 anti-icing additive, was found to exert a marked biocidal action in concentrations above 10% in fuel tank bottoms. Fuel injection grade alcohol is recommended as an antiseptic wing tank rinse. (Author).

Book excerpt: A laboratory evaluation has been made of water-soluble biocides which might be effective in controlling microbial contamination in water-compensated fuel storage tanks on naval ships. Higher concentrations of biocides were generally required for control of sulfate-reducing bacteria in steel drums simulating ships' tanks than in test-tube scale assays. At least tenfold higher concentrations were necessary when biocide additions were made after, rather than before, bacterial growth had developed extensively. A mercaptopyridine biocide was effective at the lowest concentration followed by methylene bisthiocyanate and a triazine derivative; an organoboron compound was comparatively ineffective.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an analysis of the results of studies of motor fuels ageing, conducted in laboratory and model conditions, in terms of building a system operating on-line, allowing continuous assessment of the operational usability of gasoline and diesel fuels, including those containing the addition of ethanol and FAME, respectively. This research was carried out in the framework of the project: "A system for the continuous control of the degree and rate of the liquid fuels ageing process during storage, which received co-funding from the European Regional Development Fund under the Operational Programme "Innovative Economy". The book presents an evaluation of the impact of fuel production processes on its stability and an analysis of changes in normative parameters of fuels during their storage and use. The book presents also the results of tests on the corrosive effects of fuels during storage processes. This project was co-financed by the European Regional Development Fund under the Operational Programme "Innovative Economy".

Book excerpt: A brief review of the history of microbial contamination of distillate hydrocarbon fuels is followed by a discussion of the major fungal and bacterial genera responsible and the conditions necessary for their proliferation. Microorganisms cause problems because they promote corrosion, and their physical presence leads to plugging of coalescers, filters, and orifices and the malfunction of fuel system gages. Interactions among different microbial fuel contaminants may enhance or inhibit their growth, and simple changes in conditions in the aqueous medium, such as pH, might be exploited as a means of controlling microbial growth. New biocides are available that promise to control microbial fuel contaminants at very low concentrations and in the presence of fuel tank sludge.

Available in PDF, EPUB and Kindle. Book excerpt: The Biospecialties Branch, MRMPB, 6570 Aerospace Medical Research Laboratories, initiated a research effort to support and supplement the Air Force Aeronautical Systems Division program concerned with the relationship of microbial contamination to deleterious changes in JP-4 fuel systems. Results of this program have shown the following: the majority of JP-4 fuel systems contain low levels of viable microorganisms; microorganisms are primarily associated with the water phase and rarely with the fuel phase of a JP-4 fuel/water system; JP-fuels exert a toxic effect on viable microbial cells; and microbial corrosion of aluminum alloys 7075 2024, and 7178 can occur in the laboratory but does not appear to be the major cause of corrosion in operational systems. Twenty percent ethylene glycol monomethyl ether (EGME) in a laboratory JP-4 fuel/water-bottom acts as an inhibitor to the majority of viable cells present. As a result of engineering design, it is possible that fuel capacitance probes can cease to operate as a result of microbial growth. Micronic filter materials of phenolformaldehyde impregnated paper can support the growth of microorganisms, but growth even after 43 days is insufficient to cause filter clogging, provided the filter is immersed in fuel. In addition, field surveys of JP-4 fuel handling facilities and aircraft have shown that improved housekeeping and the use of EGME have reduced the quantity of microbial contaminants initially found in the jet systems to an insignificant level.
