摘要： A hydrocarbonaceous liquid stream is modified to contain a minor amount of the amide reaction product of a polyalkylene polyamine and a neo-acid having 5 to 20 carbon atoms, the neo-acid having three alkyl groups on the carbon atom which is in the alpha position relative to the carboxylic group, whereby corrosion of iron and other metals contacted by said stream is significantly reduced.

摘要： A method of evaluating thermal stability of a fuel and an apparatus used therein. The method includes heating the fuel to a given temperature, directing light through the heated fuel a first time wherein the light is of an intensity and of a wavelength to induce fluorescence and obtaining a first fluorescence data, directing the light through the fuel at least a second time that is later in time and obtaining a second fluorescence data, and measuring any changes to fluorescence from the heated fuel over time.

摘要： An apparatus and method for determining the thermal stability of fluids, particularly for testing the deposition characteristics of fuels, comprising a conduit system which connects in series; a test fluid reservoir having a movable piston capable of discharging the fluid, a heater section in which is mounted a heated tubular member, a time reactor of a sufficient volume to increase the residence time of the fluid therein, and a water displacement reservoir. The system also incorporates a filter located at an outlet of the heater section designed to trap deposits which may form due to the heating, and a similar filter located at an outlet of the time reactor designed to trap further deposits that may form with additional time. A differential pressure measuring device is connected across each of these filters to measure the pressure drop therethrough. The apparatus also contains a water balanced reservoir and pressure regulator whereby the entire system may be maintained at a constant pressure and prevent the discharge of volatile fluids to the atmosphere.

摘要： An apparatus for determining the thermal stability of fluids, particularly for testing the deposition characteristics of fuels, comprising a conduit system which connects in series; a reservoir to contain fresh fluid having within it a movable piston capable of discharging the fluid, a heater tube housing in which is mounted a heated tubular member, a time reactor housing of a sufficient volume to decrease the flow of the fluid therethrough, a spent fluid reservoir, a filter located at an outlet of the heater tube housing designed to trap deposits which may be formed due to the heating and remain suspended in the fluid, a similar filter located at an outlet of the time reactor housing designed to trap further deposits that may form with additional time, a differential pressure measuring device connected across each of these filters to measure the pressure drop therethrough, and a valved bypass around each of these filters. The apparatus also contains a water balanced reservoir and pressure regulator whereby the entire system may be maintained at a constant pressure and not discharge volatile organic fuels to the outside.
