Analytical Instrumentation Changing Crudes, New Analysis Methods
Increasing global demand for petroleum products coupled with decreasing availability of light, sweet crude oils is changing the requirements for refinery laboratory analysis of incoming raw materials and outgoing products. As the economics of cheaper heavy crudes become more attractive, especially for complex refineries, laboratories must adjust to analysing newly challenging mixtures of varying crude composition to aid refinery process control and continually maintain strict quality standards for light and heavy fuels and other products.
Flexible laboratory techniques such as Thermo Scientific wavelength dispersive X-ray fluorescence (WDXRF) systems adapt easily to crude oil sample composition changes. Crude oil of any consistency can be quickly and accurately checked for not only sulphur content but also contaminant metals such as vanadium (V), iron (Fe) and nickel (Ni); no calibration standards are necessary using industry-leading analysis program UniQuant®
5 for unknown samples.
XRF analysis is equally adaptable to meeting changing needs in product quality control caused by variable raw materials. In addition to being the preferred lab technique for ultra-low sulphur (S) compliance testing in gasoline and diesel fuels, powerful instruments such as the ARL ADVANT’X Series also detect trace parts-per-million of corrosion-inducing contaminants such as chlorine and catalyst fines in petroleum products, as well as wear metals in oils.

Reliable, Low Cost XRF by Design
78
27
X-ray fluorescence analysis systems are workhorses in today’s petroleum labora- tories due to ease of sample prep, wide elemental analysis range and precise results. Maintaining such instruments can be costly, however, particularly when complications arise from handling a broad range of liquid samples from volatile to highly viscous. Important fac- tors to gauge the operating cost and reliability of X-ray systems include helium consumption, adequate cooling system, and X-ray tube and crystal stability and lifespan.
Thermo Scientific ARL OPTIM’X and
ARL ADVANT’X Series WDXRF spectro- meter systems are designed with reliability in mind. Novel and patented designs from over 50 years of experience provide X-ray analysis solutions with the highest reliability and lowest cost of ownership. If your lab is concerned about high instrument maintenance costs in today’s low-cost environment — including X-ray tube damage or replace- ment, helium usage and cooling system cost — or troubled by reduced analytical performance over time, contact us at
