Description Specification Description RIGAKU Online Sulfur Analysis: Advanced X-ray Transmission (XRT) Sulfur Gauge—for Crude Oil, Marine Bunker Fuel and Blending Operations Rigaku’s NEX XT is the next generation process gauge for high-level sulfur measurement (0.02% to 6% S) of crude, bunker fuel, fuel oils, and other highly viscous hydrocarbons. On-Line Sulfur Gauge This versatile, compact and robust X-ray Transmission (XRT) process gauge is specifically optimized for the 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 sulfur restrictions, interface detection of…
The quality and grade of crude oil is partly determined by the metal content as well as the sulfur content. Nickel and vanadium are important impurities to detect, as well as iron in some crudes and in residual oils. The metal content is particularly important in the quality of bunker fuels. ASTM D8252 covers the need to measure low levels of nickel and vanadium in crude to meet the new NYMEX/CME specifications for light sweet crude oil futures contract concerning maximum allowable levels the Ni and V. Rigaku offers the NEX QC+, a simple, versatile, and portable benchtop EDXRF analyzer…
Copper is one of the essential base metals in modern infrastructure. It is used for construction, electronics, machinery, automobile and marine vessel etc. in the form of electric cable and copper alloys. Copper ore mined as mainly sulfide ore is usually shipped as concentrate of 20 – 40% in copper content after processing at the plant near mine site. Copper concentrate contains a variety of impurities that are either valuable elements as byproducts, or harmful to quality in copper metal products and hazardous to the environment and human health. In modern copper deposits, ore grade of copper is decreasing while…
Fluorine is a common element in the earth’s crust formed in minerals and rocks as fluorides. The abundance of fluorine in the crust averages about 650 ppm (parts per million) and is commonly found in basalts, gabbros, andesites, granodiorites, rhyolites and granites. Marine phosphorites contain significantly higher concentrations of fluorine, averaging more than 30,000 ppm. Fluorite (CaF2), also known as fluorspar in industry, also has important uses in metallurgy including steel production, in the manufacture of ceramics and for the production of hydrofluoric acid as a precursor for other manufactured products. Optical grade fluorite with exceptional clarity is used for lenses in…
