On-line, real-time process elemental analysis by EDXRF Rigaku NEX OL
NEX QC EDXRF for Sulfur in Crude Oil
The new low cost Rigaku NEX QC benchtop EDXRF delivers compliance with the ASTM D4294 sulfur method (also methods: ISO 20847, ISO 8754, IP 496, IP 336, and JIS K 2541-4) with an easy-to-learn software interface in a robust package specifically designed for the petroleum industry. Optimized for routine determination of sulfur in petroleum, including crudes, heavies, bunker fuel and for upgrading operations, the instrument features an intuitive and modern “icon-driven” touch screen, Smartphone-style interface for easy operation and a built-in thermal printer for convenience. In addition, the new Rigaku NEX QC+ instrument delivers compliance with the ISO 13032 sulfur method for ULSD and the Rigaku NEX CG benchtop EDXRF is compliant with the ASTM D7220 method for ULSD.

Featuring advanced 3rd generation energy dispersive X-ray fluorescence (EDXRF) technology, the Rigaku NEX OL represents the next evolution of process elemental analysis for liquid stream and fixed position web or coil applications. Designed to span from heavy industrial through to food grade process gauging solutions, the NEX OL is configurable for use in both classified and non-classified areas.
To deliver superior analytical performance and reliability, the EDXRF measuring head assembly was derived from the established Rigaku NEX QC+ high resolution benchtop instrument. With this proven technology, the Rigaku NEX OL delivers rapid, non-destructive, multi-element analyses – from parts-per-million (ppm) levels to high weight percent (wt%) concentrations – for elements from aluminum (13Al) through uranium (92U). Equipped with a 50 kV X-ray tube and SDD detector – together with a standardized, optimized suite of tube filters – the Rigaku NEX OL is engineered to solve a broad range of process control applications.

Rigaku NEX XT
Rigaku’s NEX XT is the next generation process gauge for high- level total sulfur measurement (0.02% to 6% S) of crude, bunker fuel, fuel oils, and other highly viscous hydrocarbons, including residuums. This versatile, compact and robust X-ray Transmission / Absorption (XRT / XRA) process gauge is specifically optimized for the total sulfur analysis needs of refineries, pipelines, blending operations, bunkering terminals and other storage facilities. Applications for the NEX XT include bunker fuel blending to meet MARPOL Annex VI and IMO 2020 sulfur restrictions, interface detection of different grade fuels delivered via pipelines, refinery feedstock blending and monitoring, and the quality monitoring of crude at remote collection and storage facilities.

PHASE IDENTIFICATION IN THE OIL DRILLING INDUSTRY
The oil drilling industry can encounter a wide variety of samples, including
rocks, scales,
cements, cuttings, and muds throughout the drilling process. X-ray diffraction (XRD) is an essential tool for phase identification analysis of these commonly identified solids in the oil field. Three phases are identified in the figure to the right; the major is a barite phase and the two minor phases consist of calcite and quartz. The primary goal of this application is to quickly identify the phases contained within the sample material. Data collection with the MiniFlex combined with data
reduction and Search/
Match analysis using the SmartLab Studio II software package made quick work of this solid material. Using known reference standards from the International Centre for Diffraction Data (ICDD) database, the peak positions may be used to determine the phases contained with the analyzed material.
