Ametek（AMETEK）Grabner Instruments, a subsidiary of the company in Austria, has provided services to several large refineries in the United StatesGasoline saturationvapor pressureOnline monitoring solutionThis scheme significantly improves the return on investment of refining enterprises, achieves faster measurement, and significantly reduces downtime.

A large oil company in North America must ensure that the saturated vapor pressure of its products does not exceed the saturation vapor pressure limit set by the United States Environmental Protection Agency (EPA) according to the region when blending gasoline, gasoline components, and additives. Once it does not meet regulatory requirements, it will face huge economic penalties. Therefore, it is crucial to obtain accurate, reliable, and precise saturated vapor pressure detection results in the downstream section of the blending main pipeline.

Operators also need to pay close attention to the 'Giveaway' of blending - the difference between the actual saturated vapor pressure of the blended product and the specified limit. Even if the difference is only a few tenths of a pointpsiIt may also result in additional costs of millions of dollars annually. Because manufacturers can increase the saturation vapor pressure of their products by blending lower cost components (such as butane) to bring them closer to the upper limit, thereby increasing production and profit margins.

The refinery originally used non Austrian GrubnerGrabnerThe analyzer is approaching its service life and the original supplier no longer provides any technical support.In addition, the standard testing method for gasoline saturation vapor pressure used at that time required about 15 minutes to complete one measurement. Obtaining faster and closer to 'real-time' detection results will enable operators to adjust process parameters in a timely manner based on the results, thereby achieving more accurate blending control.

Therefore, the refinery urgently needs a set ofA robust and reliable online saturated vapor pressure analysis solution that meets the precision and accuracy requirements of regulatory standards while providing faster measurement results.At the same time, the new analyzer also needs to have the characteristics of easy maintenance, short investment return cycle, low overall cost of ownership, and almost zero downtime.

Based on various considerations, the refinery ultimately choseGrabner online saturated vapor pressure analysis in Grabner, AustriaThe solution. Brand reputation is a key factor - for decades,The laboratory type saturated vapor pressure tester from Grabner, Austria has always been an industry standard equipment.

In addition, Grabna, AustriaGrabner can provide accurate and reliable results certified by laboratory grade analyzers.

For this specific application, Grabner in Austria has developed a dual machine version of its online saturated vapor pressure analysis system (VPSO) called VPSOD. This model integrates two measurement cabinets into the same measurement cabinet.

Two measurement cabinets use 50% staggered phase triggering for measurement, reducing the output interval of measurement results from 7 minutes to approximately 3.5 minutes. This analyzer not only hasvery highThe measurement accuracy is also equipped with a quick replacement measuring cell. In case of a malfunction, the replacement time does not exceed 5 minutes, basically achieving zero downtime maintenance.

The first system was installed at a refinery in California. So far, eight VPSOD systems have been successfully deployed at multiple midstream sites, and some sites have even installed two sets of equipment. At present, the relevant renovation projects are still being continuously promoted, and plans are being made to implement this successful online saturated vapor pressure monitoring scheme at more key points.

Optional controller

With all new equipment being put into use, all refineries equipped with this system have successfully achieved higher efficiency and reliabilityGasoline blending process.

The VPSOD system assists operators in quickly recovering investment costs - sometimes only requiring the completion of a few oil tank blending cycles - and creates millions of dollars in additional revenue for each plant area annually.

The dual cabinet design not only shortens the measurement interval, but also allows customers to run different methods on up to six measurement channels (such as seasonal specification requirements for summer air resistance issues), so that a single device can meet the detection needs of multiple volatile specifications.

In addition, the rapid replacement measurement pool design basically eliminates downtime, while the advantage of the dual cabinet design is that even if a single cabinet experiences a fault that cannot be immediately resolved, it can ensure continuous operation without interruption.

A senior engineer responsible for the operation of multiple refineries commented:We are very satisfied with the application effect and test results,Achieved the expected goal. The Grabner team in Grabner, Austria demonstrated a friendly and cooperative attitude, professional knowledge, and efficient response capability throughout the installation process, providing us with timely technical communication and support.'
