  • Patent number: 10702832
    Abstract: A method of integrity testing porous materials that is non-destructive to the material being tested. The method includes humidifying the inlet gas stream to minimize or prevent the porous material from drying out. The inlet gas stream includes at least two gases, wherein one of the gases has a different permeability in liquid than the other, such as oxygen and nitrogen. The permeate gas stream may be subjected to a driving force such as reduced pressure to increase the flow of gases and reduce test time. Multiple porous materials can be integrity tested at the same time, such as by manifolding a plurality of them together. The integrity test is capable of detecting the presence of oversized pores or defects that can compromise the retention capability of the porous material.

    Abstract: A portable, compact, real-time and accurate sensor and method for deriving a physicochemical property of a liquid fuel, such as cetane number, carbon content, carbon/hydrogen (C/H) atomic ratio, or heating value (net heat of combustion). The sensor comprises a constant-volume ignition chamber equipped for measuring ignition delay and magnitude of a peak rise in pressure or temperature following dispensation of a liquid fuel into the chamber. The sensor utilizes air at atmospheric pressure and microliter quantities of fuel. The sensor can be implemented in real-time refinery operations for blending diesel fuels that meet government mandated cetane number standards as well as in applications for standardizing jet, biodiesel, and synthetic fuels, which presently are not classified by any physicochemical property.

  • Patent number: 10655995
    Abstract: A method of deriving a conclusion of the condition of slurry flow in a non-vertical conduit includes artificially generating a first locally heated spot on an interior surface of the conduit at the invert of the conduit and artificially generating a second locally heated spot on the interior surface of the conduit at a location angularly spaced from the first heated spot at an angular spacing of at least 90°. The temperatures of the heated spots are measured, obtaining first and second temperature values T1, T2. Electronically generated signals carrying the values T1, T2 are communicated to an electronic computing device. The computing device automatically calculates a first temperature difference T1 minus T2 and automatically derives a conclusion of the condition of slurry flow prevailing in the conduit based on the relationship between the value of the first temperature difference and a first reference parameter.

  • Patent number: 10634340
    Abstract: The dual chamber system has a source chamber and a receiver chamber. The source chamber generates a first steam in a first steam section, and the receiver chamber generates a second steam in a second steam section. The first steam is at a higher temperature than the second steam, and the first steam is at 100% quality. The first steam is injected into a mixing section of the receiver chamber to generate a condensed steam. A sensor or instrument can then be calibrated by the condensed steam. The measurement being taken with the sensor or instrument will have reliability and accuracy. The method includes generating the first steam, generating the second steam, injecting and mixing the first and second steam to form condensed steam at a metering point in the receiver chamber, and calibrating a sensor or instrument at the metering point.

  • Patent number: 10627317
    Abstract: A self-anchored piling sediment sampler is mainly composed of a sampling tube mechanism, an anchor rack mechanism and a cable. A drainer is designed for automatic drainage and air seal, so that an anchor socket can form a good anchoring condition with sediments during collection, thereby providing a stable sampling condition in cooperation with adjustable self gravity. The drainer is also applied in the sampling tube mechanism, thereby facilitating collection and seal of sediment samples. At the end of sampling, a water injector can eliminate suction force of the sediments and alleviate resistance in a lifting process. The cable is fixed to an outer sampling tube by first fixed pulleys, clamping hooks and second fixed pulleys placed on fixing rods so as to realize the conversion of the pulling force into the pressure on the sampling tube and provide a driving force for sampling.
