FIELD OF THE INVENTION
FIELD OF THE INVENTION
[0003] This invention relates to a pipeline interchange for petroleum product.
BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION
[0004] Pipelines transport different types of refined petroleum product in the same pipeline.
To do so, a pipeline operator sends different products in "batches". For example, an operator might send gasoline for several hours, and then switch to jet fuels, before switching to diesel fuel. The process of tracking the customer's batch or product through the pipeline is done through analyzing the different products within a pipeline.

The process of tracking the customer's batch or product through the pipeline is done through analyzing the different products within a pipeline.
[0005] Throughout the process, the product is measured at the receipt point in the pipeline and again upon delivery to document the amount of product moved from point A
to point B.
Many pipeline systems require pipeline owners to meet defined common product specifications for each product shipped. This requires pipeline owners to regularly analyzing many different properties of refined products in a refinery or a terminal. In these scenarios, a sample of refined product is analyzed either before entering the pipeline or during to give an analytical result.
Once the area in which the sample is taken from reaches a splitter, the operation of the splitter is adjusted based on the properties of the refined product.

[0006] Current analytical techniques, in a pipeline, require that the sample of refined product are taken with a hydrometer and adhere to ASTM guidelines such as ASTM 287. To adhere to these guideline pipeline operators must take the sample by either stopping the flow of a pipeline or taking a sample from a flowing pipeline. Stopping a pipeline is expensive and not ideal.
Taking a sample from a flowing pipeline can mean large quantities of the refined product can flow through the pipeline prior to the analytical results are being generated.

[0007] A pipeline interchange is generally known in the industry as a location where products that flow through a pipeline are separated. In refined petroleum industry, this pipeline interchange generally consists of substantially horizontal pipes that operate within either a = pipeline terminal, a refinery, a marine dock, or a rail terminal.
Typically, one pipeline will be tasked with transporting various refined petroleum products and a method of separating the refined petroleum products within the pipeline to different pipelines or storage compartments is required.
100081 There exists a need for a configuration that would allow a pipeline operator to obtain near instantaneous analytical results from a sample of refined product and relay that information to a splitter.
BRIEF SUMMARY OF THE DISCLOSURE
100091 The present embodiment describes a pipeline interchange, wherein the pipeline interchange has a refined petroleum product flowing through an upstream pipeline. The pipeline interchange can also have an automated slipstream analyzer connected to the upstream pipeline comprising an inlet, a return and an analyzer. In this embodiment, the automated slipstream analyzer is used to collect a sample, analyze the sample, generate data from the sample and return the sample of the refined petroleum product back to the pipeline. The pipeline interchange can also have an automatic splitter, downstream of the automated slipstream analyzer, capable of receiving and interpreting the data from the automated slipstream analyzer and directing the refined petroleum product into at least three different downstream pipelines, wherein at least one of the downstream pipelines is an intermix pipeline.
100101 In another embodiment, the pipeline interchange can also comprise a refined petroleum product flowing through an upstream pipeline. In this embodiment, the refined petroleum product comprises: gasoline, diesel and the intermix of gasoline and diesel.
Connected to the upstream pipeline an automated slipstream analyzer is operated simultaneously comprising an inlet, a return and an analyzer. The automated slipstream analyzer is used to continuously collect samples, continuously analyze samples, continuously generate data from the samples and continuously return the samples of the refined petroleum product flowing through the Docket No. P66-00401PCT
upstream pipeline. In this embodiment, the automated slipstream analyzer can be an infrared analyzer or a near infrared analyzer. Downstream of the automated slipstream analyzer an automatic splitter capable of responding to the data from the automated slipstream analyzer and directing the refined petroleum product into a gasoline pipeline, a diesel or other distillate pipeline, and an intermix pipeline.
[0011] In yet another embodiment, a method is taught of flowing a refined petroleum product through an upstream pipeline. The method then continuously analyzes a sample of the refined petroleum product to generate data. With this data, the flow is adjusted of the refined petroleum product towards one of at least three different downstream pipelines depending upon the data, wherein at least one of the downstream pipelines is an intermix pipeline.
BRIEF DESCRIPTION OF THE DRAWINGS
[0012] A more complete understanding of the present invention and benefits thereof may be acquired by referring to the follow description taken in conjunction with the accompanying drawings in which:
[0013] Figure I depicts one embodiment of the pipeline interchange.
[0014] Figure 2 depicts one embodiment of the pipeline interchange.
DETAILED DESCRIPTION
[0015] Turning now to the detailed description of the preferred arrangement or arrangements of the present invention, it should be understood that the inventive features and concepts may be manifested in other arrangements and that the scope of the invention is not limited to the embodiments described or illustrated. The scope of the invention is intended only to be limited by the scope of the claims that follow.
[0016] The present embodiment describes a pipeline interchange, wherein the pipeline interchange has a refined petroleum product flowing through an upstream pipeline. The pipeline interchange can also have an automated slipstream analyzer connected to the upstream pipeline comprising an inlet, a return and an analyzer. In this embodiment, the automated slipstream analyzer is used to collect a sample, analyze the sample, generate data from the sample and return the sample of the refined petroleum product flowing through the upstream pipeline. The pipeline interchange can also have an automatic splitter, downstream of the automated slipstream analyzer, capable of receiving and interpreting the data from the automated slipstream analyzer Docket No. P66-00401PCT
and directing of directing the refined petroleum product into at least three different downstream pipelines, wherein at least one of the downstream pipelines is an intermix pipeline.
[0017] In this embodiment, an upstream pipeline is generally defined as the pipeline upstream of the pipeline interchange and a downstream pipeline is generally defined as the pipeline downstream of the pipeline interchange.
[0018] In one embodiment, the pipeline interchange is an integral part of a pipeline terminal or a refinery. A pipeline interchange is generally thought of as a place where different pipelines can either intersect or diverge. The size of the upstream pipeline and downstream pipelines can vary based upon the products they are transporting. In one embodiment, the upstream pipeline and the downstream pipeline can range from about 4 inches in diameter to about 48 inches in diameter. These pipelines can either flow downstream of the pipeline interchange into other pipelines, into storage containers or storage tanks, into marine vessels, or into rail cars. These medians can also include an intermix. In one embodiment, at least three different downstream pipelines can be connected to pipeline storage tanks or intermix storage tanks.
[0019] In other embodiments, there can be two different downstream pipelines, three different downstream pipelines, four different downstream pipelines, five different downstream pipelines, six different downstream pipelines or more. The number of different downstream pipelines will depend upon the different types of refined petroleum products flowing through the upstream pipeline. In other embodiments, the one of the downstream pipelines can be dedicated for contaminates. In yet another embodiment, the downstream pipelines can be interchangeable for their uses.
[0020] The refined product that flows through the pipelines can be any liquid or gaseous product that can be derived from crude oils through processes such as catalytic cracking and fractional distillation. These products can have physical and chemical characteristics that differ according to the type of crude oil and subsequent refining processes.
Different types of refined petroleum products can include gasoline, diesel fuels, jet fuels, naphtha, marine gas oils, liquefied petroleum gasses, kerosene, lubricating oils and different types of fuel oils such as No.
2, No. 4, No. 5, and No. 6.
[0021] It is envisioned, in one embodiment, that the flow of the refined product would not be decreased when flowing through the pipeline interchange.
Docket No. P66-00401PCT
[0022] In one embodiment of the invention the analyzer is an optical analyzer. Unlike hydrometers that manually measure the density of the refined petroleum product it is envisioned that the pipeline interchange will utilize a continuous optical analyzer. In one embodiment, the pipeline interchange operates without a hydrometer. Types of optical analyzers that can be used include, infrared analyzers and near-infrared analyzers. The quantitative data generated by these analyzers can include data for premium gasoline, jet fuel, diesel fuel and unleaded gasoline.
[0023] In one embodiment, the optical analyzers can be used to analyze contaminants in the refined product. These contaminants can be compounds such as: benzene, toluene, ethylbenzene, xylenes, methyl tertiary butyl ethers, sulfur, vanadium, iron, zinc, or even lead scavengers. In other embodiments, the optical analyzer can be used to analyze properties of refined products such as: octane numbers, research octane numbers, motor octane numbers, antiknock index, boiling point, density, viscosity, molecular type compositions, elemental analysis, freezing point, carbon residue, pour point, cloud point, vapor pressure, reid vapor pressure, flammability range, wax and asphaltene contents, cetane number, aniline point, and carbonto-hydrogen ratios.
[0024] By utilizing optical analyzers, the automatic splitter will be able to receive rapid and reliable data regarding the composition of the refined petroleum product that is flowing through the pipeline. Additionally, the samples taken and returned to the pipeline by the optical analyzers allow the refined petroleum product to be reused instead of conventional hand measurement methods that can modify the refined petroleum product and therefore make it unsuitable of being returned to the pipeline or being used as a conventional fuel.
[0025] It is theorized that by using a continuous optical analyzer that the data generated can be received and interpreted by the automatic splitter faster than conventional methods. The automatic splitter can then be able to determine the precise moment the refined petroleum product changes from one type of petroleum product to an intermix and from the intermix to another type of petroleum product. Intermix is defined as a random mixture of on-specification fuels that due to their mixing no longer meet a specific fuel specification, such intermix fluids can be directed to an intermix pipeline, which can be connected to an intermix storage tank, which will be redistributed back to a refinery to generate petroleum products that meet product specification requirements.
[0026] In other embodiments, it is envisioned that automatic splitter can then be able to determine the precise moment the refined petroleum product changes from one type of petroleum Docket No. P66-00401PCT
product to one that contains contaminates. The automatic splitter then would direct the contaminated refined product to a pipeline that can be redistributed back to a refinery instead of to storage tanks for consumer use.
[0027] The automatic splitter can be from 1 meter to 500 meters downstream of the automated slipstream analyzer. In one embodiment, the automatic splitter can be up to 1 kilometer, 2 kilometers or even 5 kilometers downstream of the automated slipstream analyzer.
The automatic splitter can be any splitter capable of directing the flow of the upstream pipeline into the different downstream pipelines. This can consist of a valve on each of the downstream pipelines or a central splitter used to direct the flow of fluid into one or more of the downstream pipelines.
[0028] In one embodiment, the automated slipstream analyzer is located inline of the upstream pipeline. As shown in Figure 1, a side profile of an upstream pipeline 2 is shown with an automated slipstream analyzer 4 deposed within. The automated slipstream analyzer has an inlet 6 capable of collecting a sample and a return 8 capable of returning the sample of refined petroleum product flowing through the upstream pipeline. The automated slipstream analyzer can analyze the sample collected from the inlet and generate data from the sample. The data generated from the automated slipstream analyzer can be transferred wirelessly 10 or by a wired connection 12 to an automatic splitter 14 located downstream of the automated slipstream analyzer. As depicted in this embodiment, automatic splitter comprises a valve on each of the downstream pipelines, in other embodiments this could be different. In one embodiment as shown in Figure 1, the automatic splitter is able to direct the refined petroleum product into at least three different downstream pipelines 16, 18 and 20.
[0029] As depicted in Figure 1, the automated slipstream analyzer is placed in the center of the upstream pipeline. It is understood that in different embodiments the automated slipstream analyzer can be placed anywhere within the upstream pipeline capable of collecting a sample of the refined petroleum product.
[0030] In another embodiment, the automated slipstream analyzer operates as a sample loop adjacent to the upstream pipeline. As shown in Figure 2, upstream pipeline 50 has an automated slipstream analyzer 52 connected to the pipeline. The automated slipstream analyzer has an inlet 54 capable of collecting a sample and a return 58 capable of returning the sample of refined petroleum product flowing through the upstream pipeline. The inlet can be regulated to be a continuous flow or intermittent based on user needs. The automated slipstream analyzer can analyze the sample collected from the inlet and generate data from this sample. The data generated form the automated slipstream analyzer can be transferred wirelessly 60 or by a wired connection 62 to an automatic splitter 64 located downstream of the automated slipstream analyzer. As depicted in this embodiment, automatic splitter comprises a valve on each of the downstream pipelines, in other embodiments this could be different. In one embodiment as shown in Figure 2, the automatic splitter is able to direct the refined petroleum product into at least three different downstream pipelines 66, 68 and 70.
[0031] In closing, it should be noted that the discussion of any reference is not an admission that it is prior art to the present invention, especially any reference that may have a publication date after the priority date of this application.
[0032] Although the systems and processes described herein have been described in detail, it should be understood that various changes, substitutions, and alterations can be made without departing from the scope of the invention as defined herein below. Those skilled in the art may be able to study the preferred embodiments and identify other ways to practice the invention that are not exactly as described herein.

The number of different downstream pipelines will depend upon the different types of refined petroleum products flowing through the upstream pipeline. In other embodiments, the one of the downstream pipelines can be dedicated for contaminates. In yet another embodiment, the downstream pipelines can be interchangeable for their uses.
[0020] The refined product that flows through the pipelines can be any liquid or gaseous product that can be derived from crude oils through processes such as catalytic cracking and fractional distillation. These products can have physical and chemical characteristics that differ according to the type of crude oil and subsequent refining processes.
Different types of refined petroleum products can include gasoline, diesel fuels, jet fuels, naphtha, marine gas oils, liquefied petroleum gasses, kerosene, lubricating oils and different types of fuel oils such as No.
2, No. 4, No. 5, and No. 6.
[0021] It is envisioned, in one embodiment, that the flow of the refined product would not be decreased when flowing through the pipeline interchange.
Docket No. P66-00401PCT
[0022] In one embodiment of the invention the analyzer is an optical analyzer. Unlike hydrometers that manually measure the density of the refined petroleum product it is envisioned that the pipeline interchange will utilize a continuous optical analyzer. In one embodiment, the pipeline interchange operates without a hydrometer. Types of optical analyzers that can be used include, infrared analyzers and near-infrared analyzers. The quantitative data generated by these analyzers can include data for premium gasoline, jet fuel, diesel fuel and unleaded gasoline.
[0023] In one embodiment, the optical analyzers can be used to analyze contaminants in the refined product. These contaminants can be compounds such as: benzene, toluene, ethylbenzene, xylenes, methyl tertiary butyl ethers, sulfur, vanadium, iron, zinc, or even lead scavengers. In other embodiments, the optical analyzer can be used to analyze properties of refined products such as: octane numbers, research octane numbers, motor octane numbers, antiknock index, boiling point, density, viscosity, molecular type compositions, elemental analysis, freezing point, carbon residue, pour point, cloud point, vapor pressure, reid vapor pressure, flammability range, wax and asphaltene contents, cetane number, aniline point, and carbonto-hydrogen ratios.
[0024] By utilizing optical analyzers, the automatic splitter will be able to receive rapid and reliable data regarding the composition of the refined petroleum product that is flowing through the pipeline. Additionally, the samples taken and returned to the pipeline by the optical analyzers allow the refined petroleum product to be reused instead of conventional hand measurement methods that can modify the refined petroleum product and therefore make it unsuitable of being returned to the pipeline or being used as a conventional fuel.
[0025] It is theorized that by using a continuous optical analyzer that the data generated can be received and interpreted by the automatic splitter faster than conventional methods. The automatic splitter can then be able to determine the precise moment the refined petroleum product changes from one type of petroleum product to an intermix and from the intermix to another type of petroleum product. Intermix is defined as a random mixture of on-specification fuels that due to their mixing no longer meet a specific fuel specification, such intermix fluids can be directed to an intermix pipeline, which can be connected to an intermix storage tank, which will be redistributed back to a refinery to generate petroleum products that meet product specification requirements.
[0026] In other embodiments, it is envisioned that automatic splitter can then be able to determine the precise moment the refined petroleum product changes from one type of petroleum Docket No. P66-00401PCT
product to one that contains contaminates. The automatic splitter then would direct the contaminated refined product to a pipeline that can be redistributed back to a refinery instead of to storage tanks for consumer use.
[0027] The automatic splitter can be from 1 meter to 500 meters downstream of the automated slipstream analyzer. In one embodiment, the automatic splitter can be up to 1 kilometer, 2 kilometers or even 5 kilometers downstream of the automated slipstream analyzer.
The automatic splitter can be any splitter capable of directing the flow of the upstream pipeline into the different downstream pipelines. This can consist of a valve on each of the downstream pipelines or a central splitter used to direct the flow of fluid into one or more of the downstream pipelines.
[0028] In one embodiment, the automated slipstream analyzer is located inline of the upstream pipeline. As shown in Figure 1, a side profile of an upstream pipeline 2 is shown with an automated slipstream analyzer 4 deposed within. The automated slipstream analyzer has an inlet 6 capable of collecting a sample and a return 8 capable of returning the sample of refined petroleum product flowing through the upstream pipeline. The automated slipstream analyzer can analyze the sample collected from the inlet and generate data from the sample. The data generated from the automated slipstream analyzer can be transferred wirelessly 10 or by a wired connection 12 to an automatic splitter 14 located downstream of the automated slipstream analyzer. As depicted in this embodiment, automatic splitter comprises a valve on each of the downstream pipelines, in other embodiments this could be different. In one embodiment as shown in Figure 1, the automatic splitter is able to direct the refined petroleum product into at least three different downstream pipelines 16, 18 and 20.
[0029] As depicted in Figure 1, the automated slipstream analyzer is placed in the center of the upstream pipeline. It is understood that in different embodiments the automated slipstream analyzer can be placed anywhere within the upstream pipeline capable of collecting a sample of the refined petroleum product.
[0030] In another embodiment, the automated slipstream analyzer operates as a sample loop adjacent to the upstream pipeline. As shown in Figure 2, upstream pipeline 50 has an automated slipstream analyzer 52 connected to the pipeline. The automated slipstream analyzer has an inlet 54 capable of collecting a sample and a return 58 capable of returning the sample of refined petroleum product flowing through the upstream pipeline. The inlet can be regulated to be a continuous flow or intermittent based on user needs. The automated slipstream analyzer can analyze the sample collected from the inlet and generate data from this sample. The data generated form the automated slipstream analyzer can be transferred wirelessly 60 or by a wired connection 62 to an automatic splitter 64 located downstream of the automated slipstream analyzer. As depicted in this embodiment, automatic splitter comprises a valve on each of the downstream pipelines, in other embodiments this could be different. In one embodiment as shown in Figure 2, the automatic splitter is able to direct the refined petroleum product into at least three different downstream pipelines 66, 68 and 70.
