    摘要: A real-time system and method for measuring stickies by separating high molecular weight non-fibrous species from low molecular weight non-fibrous species and sensing the concentration of the high molecular weight species. Specifically, a fiber slurry containing stickies is filtered to remove fibers, fiber debris, and other large contaminant particles from the fiber slurry, after which the carbon content of the filtered sample is measured. Next, the filtrate is ultrafiltered to separate stickies having a high molecular weight from the filtrate, and subsequently, the carbon content of the ultrafiltered sample is measured. Finally, the carbon contents are used to determine the microstickies concentration in the fiber slurry.

    摘要: Subsurface contaminants are readily and inexpensively detected and measured by means of a test head positioned at the subsurface site and forming a protected test chamber for the liquids to be tested. The head encloses the end faces of fiber optic elements which carry radiation to the liquid sample from a test instrument located at the surface and which return radiation from the sample to the instrumentation. A connector positioned at the surface decouples the head from the instrumentation, so that the same instrumentation can service a larger number of test sites.

    摘要: A method includes identifying, by pre-set criteria, a first plurality of optical channels and a second plurality of optical channels using optical data generated from a plurality of optical filters of a tester tool. The method also includes determining, from the optical data, a first plurality of fluid types detected by each channel in the first plurality of optical channels using a bootstrap fluid identification technique and determining, from the optical data and the first plurality of fluid types, a second plurality of fluid types detected by each channel in the second plurality of optical channels using a guided fluid identification technique. Further, the method includes generating a spectral signature indicating fluid types for each channel within the tester tool based on the first plurality of fluid types and second plurality of fluid types.

    摘要: An opaque slurry chemical constituent measurement system includes a cross-flow or membrane filter having a porous filter element connected between a global slurry loop and a spectrometer. The opaque slurry particles cannot pass through the filter element but pass through the filter cartridge into the day tank, while the chemical constituent to be measured permeates through the filter element to the spectrometer, where it is measured, and thence to a reservoir. About once every five minutes the porous filter element is reverse flushed for less than a second to clear the filter pores. One to several times per hour, the reservoir is emptied into the day tank. The system provides essentially continuous measurement of the slurry chemical composition, does not consume reagent chemicals, does not create a chemical waste stream, and provides high reliability and low maintenance by preventing the abrasive slurry particles from contacting the fluidic sampling valves.

    摘要: A method of performing an optical analysis of a liquid containing dissolved gas includes transferring an amount of the liquid containing the dissolved gas from a reservoir into a holder of a flow system of the optical analyser, holding the amount of the liquid in the holder at around ambient pressure for a period such that a portion of the dissolved gas is expelled from the amount of liquid held in the holder while the holder is open to a waste reservoir, transferring at least a portion of the amount of the liquid containing the dissolved gas held in the holder under a pressure above ambient into a measurement cell of the optical analyser as a liquid sample, and performing the optical analysis of the liquid sample from a detection of optical radiation by an optical detector after its interaction with the liquid sample in the measurement cell.

    摘要: An optical gas densitometer is provided comprising a conical filter portion having a front and rear end disposed to the inside of a cell portion and formed into a conical shape, which has a reflection mirror disposed to the inside of the front end thereof, windows disposed at the rear end thereof and in which the angle between an incident optical beam and an exiting optical beam is predetermined. Plate means at the front end of the filter and formed in a space between the inside of the cell portion and the outside of the conical filter portion, divides the space into a gas feed channel below the plate means and a gas exhaust channel above the plate means. An opening channel is disposed between the gas feed channel and the gas exhaust channel towards the rear end of the filter. A partition plate connected to the plate means at the front end of the filter, divides a gas sampling tube into first and second channels which correspond to the feed channel and exhausting channel, respectively.
