摘要： A method for improved handling of a blended fuel includes obtaining a sample of the blended fuel from a storage tank; cooling the same until the sample separates into phases; and determining a risk that the fuel in the storage tank will separate based on the cooling step. An apparatus for assessing the risk of phase separation of a blended fuel includes a test cavity for holding a sample of the blended fuel from a storage tank; a heat transfer device for cooling the sample in the test cavity; and at least one sensor for indicating when the sample in the test cavity has separated into phases.

摘要： A method of determining physico-chemical properties of a petroleum sample from two-dimensional gas chromatography. The amounts of molecular compounds present in the sample are determined by means of two-dimensional gas chromatography. At least one physical property, such as the octane number, is then determined from these amounts. A previously calibrated relation connecting the physical property to the amounts is used to this end.

摘要： The invention concerns a method for determining the vanishing temperature of petroleum product crystals, characterized in that it comprises the following steps: introducing the sample to be analyzed in a measuring cell (4), arranged in a cryostatic chamber (1); connecting a laser emitter (6) and an associated optical receiver (7) to pass an optical beam through the sample to be analyzed and recording the light intensity received by the receiver (7); gradually lowering the temperature of the cryostatic chamber (1) then increasing it again gradually while recording the curve representing the variations in the light intensity received by the receiver (7) based on the temperature; and determining the vanishing temperature of the crystals from said curve.

摘要： A cloud point monitoring device which includes thermal conductive surface, cooler, temperature sensor, detection volume, detection wall unit, fiber optic cables for transmitting light, lighter emitter, light detector, and a data acquisition and control unit. The cloud point monitoring device provides an instrument to accurately measure the cloud point of diesel fuel indicate the approximate level of crystallization in diesel fuel that has been chilled beyond its cloud point and indicate the approximate energy content of diesel fuel. The cloud point monitoring device design allows it to be made small enough to be mounted in a fuel system of a vehicle.

摘要： Apparatus for monitoring the cloud point of a liquid, or the temperature at which any light scattering phase occurs therein, comprising a light-proof and light-absorbing chamber, and a liquid sample-receiving receptacle within the chamber having a bottom formed by a non-light-scattering surface; this surface being in thermal contact with a heating or cooling device, such as a thermoelectric cooler, and with a temperature measurement device. The chamber can be opened to allow access to the receptacle so that sample liquid can be placed therein. A light beam source is located to direct a beam of light onto the surface at an incident angle so that light from the beam is reflected or absorbed by the surface. A light detector including a lens and an array of detection cells is arranged so as to detect scattered light which is produced when solid material forms in the liquid as it is cooled or disappears on heating. The melting point of a solid, or the boiling point of a liquid, can be detected, in additoin to cloud points.

摘要： Disclosed are methods and apparatus for determining phase transition temperatures and, more particularly, for determining cloud, fluidity, freezing, and haze points of hydrocarbon fuels and hydrocarbon/oxygenate fuel blends. The attenuation of laser light as it passes through the sample, then through a laser line filter, and then into a photodetector is used to determine the transition temperature.

摘要： The pour point of a catalytically dewaxed hydrocarbon oil is determined manually by the ASTM D-97-66 method and also by automatic apparatus such as the Herzog Electronic Pour Point Automatic MC 850 apparatus. A substantial divergence of the two indicates contamination by a waxy hydrocarbon oil such as the feedstock to the dewaxing process.
