Abstract

In one embodiment, a pipeline interchange is described where a first product flows through a first pipeline and a second product flows through a second pipeline. In this embodiment, a first product automated analyzer is situated near the first pipeline to physical and/or chemically analyze the first product and generate first product data. Additionally, in this embodiment, a second product automated analyzer is situated near the second pipeline to physical and/or chemically analyze the second product and generate second product data. A pipeline interchange is connected downstream to both the first pipeline and the second pipeline, wherein the pipeline interchange blends the first product flowing through the first pipeline with the second product flowing through the second pipeline. A third pipeline is connected downstream to the pipeline interchange, wherein the third pipeline flows a blended product created from the blending of the first product and the second product in the pipeline interchange. A data analyzer is also positioned to interpret the first product data and the second product data and communicate adjustments to the flow of both the first product and the second product to achieve desired physical and/or chemical characteristics in the blended product.

First claim

The invention claimed is:

1. A pipeline interchange comprising:
a first product flowing through a first pipeline, wherein a first product automated analyzer is situated near the first pipeline to physically or chemically analyze the first product and generate first product data;
a second product flowing through a second pipeline, wherein a second product automated analyzer is situated near the second pipeline to physically or chemically analyze the second product and generate second product data;
a pipeline interchange connected downstream to both the first pipeline and the second pipeline, wherein the pipeline interchange blends the first product flowing through the first pipeline with the second product flowing through the second pipeline;
a third pipeline connected downstream to the pipeline interchange, wherein the third pipeline flows a blended product created from the blending of the first product and the second product in the pipeline interchange; and
a data analyzer capable of interpreting the first product data and the second product data and communicate adjustments to the flow of both the first product and the second product to achieve desired characteristics in the blended product,
wherein the first product automated analyzer is selected from the group consisting of: infrared analyzer, near infrared analyzer, ramen analyzer, acoustic analyzer, UV-visible analyzer, density analyzer, NMR analyzer, viscometer analyzer, terahertz spectroscopy analyzer, conductivity analyzer, pH analyzer, mass spectrometry analyzer, turbidity analyzer, particle size analyzer, electron loss spectroscopy analyzer, fluorescence analyzer, micro- and nano-electromechanical systems analyzers, chromatography analyzer electrophoresis analyzer, microwave resonance analyzer, cavity-ringdown analyzer, cavity- enhanced analyzer, dielectric spectroscopy, surface plasmon resonance analyzer, quartz crystal microbalance analyzer, biosensing analyzers, time resolved spectrometers, and micro total analytical systems analyzer and combinations thereof, and
wherein the analyzing of the data from the automatic analyzer comprises periodically transforming the spectral data to produce transformed spectral data and correlating the transformed spectral data with at least one physical and/or chemical characteristic of the product stream flowing through the upstream pipeline, wherein the correlating indicates a change in the product stream from the first stream to a transmix stream and to a second stream, wherein changes in at least one physical and/or chemical characteristic of the product stream are determined by:
converting the spectral data to discrete digitized data points that are then transformed to produce wavelet coefficients data according to wavelet theory by applying a mother wavelet consisting of a member of the Symlet family of mother wavelets at the third level of decomposition or greater to produce transformed wavelet coefficients data; and
classifying the stream represented by the transformed wavelet coefficients data as either the first stream, a transmix stream or a second stream having distinct chemical characteristics from the first stream by presenting the transformed wavelets coefficients data to a trained genetic algorithm, wherein the trained genetic algorithm performs the classifying by examining identifying data features that collectively identify a particular stream as a member of the first stream, the second stream or a transmix stream.

2. The pipeline interchange of claim 1 , wherein the data analyzer utilizes chemometrics to determine the modelling relationship of the blended product to the first product and the second product.

5. The pipeline interchange of claim 4 wherein the analyzing of the data from the automatic analyzer comprises periodically transforming the spectral data to produce transformed spectral data and correlating the transformed spectral data with at least one physical and/or chemical characteristic of the product stream flowing through the upstream pipeline, wherein the correlating indicates a change in the product stream from the first stream to a transmix stream and to a second stream, wherein changes in at least one physical and/or chemical characteristic of the product stream are determined by:
converting the spectral data to discrete digitized data points that are then transformed to produce wavelet coefficients data according to wavelet theory by applying a mother wavelet consisting of a member of the Symlet family of mother wavelets at the third level of decomposition or greater to produce transformed wavelet coefficients data; and
classifying the stream represented by the transformed wavelet coefficients data as either the first stream, a transmix stream or a second stream having distinct chemical characteristics from the first stream by presenting the transformed wavelets coefficients data to a trained genetic algorithm, wherein the trained genetic algorithm performs the classifying by examining identifying data features that collectively identify a particular stream as a member of the first stream, the second stream or a transmix stream.

6. The pipeline interchange of claim 1 , wherein the first product automated analyzer chemically analyzes the first product inside the pipeline without extracting a sample.
