On-line Analysis of Sulphur in Petroleum Streams

Mar 19 2024

Whether used for crude oil blending and monitoring, assaying or blending marine bunker fuels, or custody transfer, the Rigaku NEX XT is an excellent on-line tool for sulphur analysis in petroleum streams. It is well suited to meet the varying demands of the industry and help maximise profitability.

On-line Sulphur Measurement (0.04 to 6 wt%)

NEX XT delivers on-line, real-time X-ray transmission (XRT) measurement of sulphur from 400 parts-per-million (ppm) to 6 wt% for various petroleum streams. It represents the next evolution of process solutions for sulphur measurement of crude, bunker fuel, fuel oils, and other highly viscous hydrocarbons, including residuums.

Optimised for total sulphur analysis needs, NEX XT is versatile, compact, and specifically designed to address the needs of refineries, pipelines, blending operations, bunkering terminals, and other storage facilities.

  • Ideal for crude oil and refinery feedstock blending and monitoring
  • Ideal for marine fuel blending and monitoring to meet IMO MARPOL regulations
  • Quality monitoring of crude at remote collection and storage facilities
  • Monitor high-temperature vacuum gas oils

Featuring uniquely engineered hardware and novel proprietary software technologies, the NEX XT system is faster, more sensitive, and much more compact than competitive systems. NEX XT performs continuous, reliable sulphur monitoring at pressures up to 100 bar (1450 psig) and up to 200°C in custom configurations. NEX XT operates as a standalone analyser or provides real-time closed-loop control when tied into a blending or plant-wide automation system.

Its other key features are a simplified user interface, reduced standards requirement, automatic density compensation, password protection, and a standard platform for communicating sulphur results to a DCS. Due to its unique design and robust construction, sample conditioning and recovery systems are typically not required.

  • Compact and designed for unattended operation
  • No consumables or routine maintenance required
  • User-adjustable data update frequency
  • Reduced standards requirements
  • No sample condition or recovery system
  • No radioisotopes

What is the XRT method?

X-ray Transmission (XRT) gauging has long been an accepted technique for measuring total sulphur (S) in heavy hydrocarbon process streams. Whether used for pipeline switching, crude oil blending, or to assay or blend marine and bunker fuels, the NEX XT XRT process analyser is suited for rigorous process environments, with pressures up to 1450 psig and temperatures up to 200°C.

X-ray transmission gauging involves measuring the attenuation of a monochromatic X-ray beam at a specific energy (21 keV) that is specific to sulphur (S). In practice, a process stream passes through a flow cell where sulphur (S), in the hydrocarbon matrix, absorbs X-rays transmitted between an X-ray source and detector. The recorded X-ray intensity is inversely proportional to the sulphur concentration. Thus, the highest sulphur levels transmit the least X-rays.
