ABB FT-NIR application in blending

Refined oil blending

In FT-NIR application ABB the FT-NIR application ABB oil refining industry, finished product blending is an important technology. This is the last stage of the crude oil processed into useful fuel. Blending mixer from a number of process device component oil blending, to provide compliance with government departments, international organizations and customer demand of refined oil products. Due to the blending is the last stage of the oil refining process, therefore, to optimize the process is of vital importance. Regardless of the upstream process equipment work efficient, if blending optimization, finally produce the fuel poor quality, that the whole production process can be pain and no gain. In various ways, blending is the need to optimize the process, excellent blending process can bring considerable economic returns for refinery.

ABB in the field of optimal blending equipment has very rich experience. Optimizing blending equipment priority is for determination of the nature of the need to optimize the <a href="/searchfanan.html?search=parameter&select=7">parameters. Industry in the prestigious ABB FTIR (Fourier transform infrared analysis technology) solution can bring many benefits to the refinery. ABB, reliable, excellent durability of NIR spectrometer (near infrared spectrometer) is the core of the whole analysis system. ABB spectrometer using the Fourier transform near infrared spectral analysis technology, its designed specifically for use in various process conditions, therefore, the user need not worry about damage when using sensitive optical instruments.

ABB's spectrometer is encapsulated in rugged industrial standard cabinets, made explosion-proof certification to work in the danger zone. At the same time, the spectrometer has integrated the internal temperature control sampling system, can provide a stable and precise measurement results. In addition, ABB spectrometer also provides operating software based on Windows environment, with the refinery DCS system (ModBUS, OPC, 4-20 ma) for integration.

ABB is committed to form a close partnership with you and help you achieve suit your specific needs, customized solutions for you. We will also provide customers with a wide range of support services, process improvement, the scene and the otc personnel training and project start-up and after-sales service. Since formally established in 1973, ABB has been engaged in the research and development of FTIR spectrometer and its auxiliary equipment and manufacturing. Due to long-term focus on research and development and is committed to establish close partnership with customers, we are using FTIR and FT - NIR analysis technique for quantitative analysis of the field has accumulated rich experience, and developed its own unique technology. Based, our products are widely used at present, there are more than 300 sets of analyzer are for refining blending and other refining units application services. We already have a save nearly a global database of 40000 spectra. This database will be great help for we implement new blending projects, greatly improve the speed project putting-in-service proactively.

Traditional methods of blending/problem

Of (among) all the oil refining process, oil blending is the most critical process affects the quality of the finished product. High quality of the finished product has clear rules in nature, only conform to the nature of these standards, the product will have a good sale.

If can effectively meet these standards (as little as possible to use the high cost of blending component, the maximum use of the lowest cost of blending components), must be the product (and blending components) of various property parameters for fast and accurate measurement.

Is then sent to measure the nature of the product quality in real time on-line blending optimizer, to ensure that the blending process and economic efficiency, and achieve the desired objective blending.

The task of conventional methods, generally need to use a large number of physical properties of the analyzer and on-line equipment to complete, as to monitor the nature and octane number blending. Analysis of a complete set of equipment is expensive, from purchase to use maintenance cost is very high.

Solution/benefits

ABB offers all kinds of used for on-line optimization of gasoline diesel blending of FT - online NIR analyzer, can carry on the gasoline for diesel oil blending of multiple components as well as to the finished product, multiple quality properties of blending components for quick and accurate measurement. Method is to use a variety of models, model portability, using ABB laboratory analyzer and on-line analyzer determination of two sets of data to establish a comprehensive analysis of database, all of these, make sure project can quickly start, at the same time, the correction of the specific project work to a minimum. Because of this, compared with using the traditional oil blending method, ABB will provide solution greatly reduce the investment cost.

Through real-time, accurate determination of the finished product quality, ABB provides analytical instruments allow you to any one online optimizing blending control optimizer to set the required product quality, make the product blending processing again fell to the lowest, the quality loss reduce to a minimum. In meeting the quality objectives of the finished product at the same time, using low cost of blending components as much as possible. Blending the blending components arrive head, accurately measure all the property parameters of blending component, help the optimizer to determine the best blending formula.

The performance of the analyzer and repeatability

Due to the use of the related technology, and use good statistics, FT - online NIR analyzer provided with ASTM lab analysis accuracy can be used to establish calibration model of reference data. However, with the use of traditional multiple analyzer blending optimization scheme, compared to use ABB's FT - online NIR analyzer to the extent to improve the analysis of the repeatability and the availability of the analyzer. Because of the light hydrocarbon component of oil is easy to sampling inspection, to analyze its simplicity. Light hydrocarbon component of oil, for example, compared with traditional routine physical analyzer, FT - NIR analyzer using ultra low noise optical technology can provide incredible analysis repeatability.

For operators, FT - NIR analyzer in gasoline diesel quality offer excellent repeatability of the measurement is extremely important. Only in a case with reliability and repeatability, the analyzer can be accurately found blending process blending subtle changes of the nature of particular average. Due to the influence of noise as a result, these changes are mortal, the traditional analysis method may be unable to show up. Because that have taken place in nature of the deviation, the operator or a multi-parameter monitoring system need to adjust the process, in order to maintain optimum blending quality. In addition, because compared with the traditional lab methods, repetitive greatly improved, this means that the mass loss will be greatly reduced

Due to component analysis used in oil refining process and equipment optimization process of FTIR analyzer is a secondary analysis method, they need to use the reference data and establish the related model according to the laboratory to work, therefore, to ensure its effectiveness, and maintain a standard associated with laboratory constantly updated SQC performance track record is crucial. In this regard, ASTM (American society of testing materials) provides some useful guidance for correction model specification, such as ASTM D6122 and ASTM specification E1655 guidance.

Using FTIR online analyzer, it is very important to maintain its reliability and credibility. Especially for key process optimization and quality loss control applications, especially. Should compare the field laboratory reference data to monitor the performance of the online analyzer, only in this way, can the deviation occurs, rapid detection and adjust in time. Also need to laboratory reference data in the middle of the process error and deviation of the corresponding compensation, at the same time also should take into account the correction model may be affected by blending formula major changes and the influence of blending components of effectiveness.
