- AN-NIR-113Research octane number (RON) determination in isomerate
The standard method to determine RON in isomerate is with expensive and maintenance-intensive engines. In contrast to this, the research octane number can also be analyzed by near-infrared spectroscopy (NIRS). NIRS provides accurate results within one minute without the need for any sample preparation or chemicals.
- AN-NIR-114Determination of RON, aromatics, benzene, olefins, and density in reformate by NIRS
The determination of key quality parameters of reformate—namely research octane number (RON, ASTM D2699-19), aromatic content (ASTM D5769-15), benzene content, olefin content, and density—requires time-consuming and laborious conventional methods. In contrast, the Metrohm DS2500 Liquid Analyzer can measure all of these parameters, providing results within one minute without any sample preparation.
- AN-PAN-1052Online process monitoring of octane number during catalytic reforming
In refineries, high octane products are desired since they are used to produce premium gasoline. Catalytic reforming converts heavy naphtha into a high octane liquid product called reformate (a mixture of aromatics and iso-paraffins C7 to C10). The reformate must be constantly monitored to ensure high throughput along the refining process. Traditionally, the octane numbers can be measured by two different methodologies: Inferred Octane Models (IOM) and laboratory octane engine analysis. However, these do not provide «real-time» results and require constant maintenance and human intervention to adapt to current operation conditions. «Real-time» analysis of the octane number in fuels can be performed online via near-infrared spectroscopy (NIRS) technology, which fits well within the international standards (ASTM). Utilization of a Metrohm Process Analytics NIRS XDS Process Analyzer (ATEX version) in conjunction with a sample preconditioning system makes analysis of the octane number simple, fast, and reliable, allowing quick adjustments to the process for a better quality product and higher profitability.
- WP-054Aumente a eficiência no laboratório de controle de qualidade: Como o NIRS ajuda a reduzir os custos em até 90%
A subestimação dos processos de controle de qualidade (CQ) é um dos principais fatores que levam a falhas internas e externas de produtos, que, segundo relatos, causam uma perda de faturamento entre 10–30%. Como resultado, muitas normas diferentes são implementadas para apoiar os fabricantes em seus processos de CQ. No entanto, o tempo para obter resultados e os custos associados aos produtos químicos podem ser excessivos, levando muitas empresas a implementar a espectroscopia de infravermelho próximo (NIRS) em seu processo de CQ. Este documento ilustra o potencial da NIRS e mostra os potenciais de economia de custos de até 90%.
