  • Patent number: 9944867
    Abstract: A computer implemented blend control system and method for preparation of a hydrocarbon blend from a plurality of components drawn from respective component tanks have been disclosed. The system, in accordance with the present disclosure includes at least one sensor and analyzer adapted to sense and analyze a first attribute of at least one of the components for obtaining first attribute data. The system further includes, at least one optimizer having a data storage means for storing attribute based model data. The optimizer receives the first attribute data and transmits the received first attribute data to a comparator which computes an optimized proportion data between each of the component streams to enable selective drawing of each of the component streams in accordance with the optimized proportion data for preparing the hydrocarbon blend.

  • Patent number: 9939821
    Abstract: A computer implemented blend control system and method for preparation of a hydrocarbon blend from a plurality of component streams have been disclosed. The system includes a product tank for receiving a mixture comprising the plurality of component streams. The system further includes a sensor and analyzer adapted to sense and analyze a first attribute of the received mixture for obtaining a first attribute data. The system further includes an optimizer which stores the attribute based model data, receives the first attribute data and compares the received first attribute data with the attribute based model data to compute an optimized proportion data, based on which the component streams are selectively drawn into the product tank for preparing the hydrocarbon blend.

  • Patent number: 7362448
    Abstract: A residue detection system collects at least one of the spectrum and image from a measurement region on a sample. Spectral analysis is performed on the collected spectrum to determine whether residue is present and if so the thickness of the residue. The spectral analysis uses a calibration metric that correlates a monitoring parameter to the thickness of the residue. The monitoring parameter is at least one of the reflectance value at one or more of the local minima and maxima in the spectrum, the shape of one or more of the local minima and maxima in the spectrum, and the difference in reflectance values between at least two of the local minima and maxima in the spectrum. In one embodiment, imaging analysis is performed on the collected image of the measurement region if no residue is detected by the spectral analysis.
