WebbAsphaltenes are formed when diesel fuel is heated under high pressure as it passes through today’s high pressure fuel injection systems. The drastic increase in pressure with these new fuel injection system combined with high temperatures actually cook the fuel and can create small pieces of tar about 2 microns in size — asphaltenes. WebbThe study of asphaltene colloidal properties has been motivated by their propensity to aggregate, flocculate, pre-cipitate, and adsorb onto interfaces. The tendency of as-phaltenes to participate in colloidal and interfacial phenom-ena has posed great challenges for the petroleum industry. Problems associated with well production, pipeline trans-
WebbDehshibi et al. (2024) studied the effects of low-frequency, high-power ultrasonication (30kHz) on asphaltene precipitation / flocculation and deposition under temperature control. Ultrasonication reduced asphaltene deposition. Ultrasonic waves and the generated acoustic cavitation caused increasing oil production by oil layering mechanism. Webb3 juli 2012 · They’re lurking out there in diesel fuel tanks: Small particles of debris, too tiny to see, wearing out fuel injectors; water, lying in wait at the bottom, causing corrosion debris, reducing fuel lubricity, and hosting microbes (fungi and bacteria) that feed on the fuel and form filter-plugging slime and corrosive acids; and, finally, assorted …
