Online Sulfur in Heavy Oils

AppNote XRT1059: Online Sulfur in Heavy Oils


Process sulfur application overview

On-line, real time X-ray Transmission (XRT) measurment of sulfur (S) in heavy or light oils to satisfy the needs of refineries, pipelines, blending operations, bunkering terminals and other storage facilities. Applications include bunker fuel blending to meet MARPOL Annex VI sulfur restrictions, interface detection of different grade fuels delivered via pipelines, refinery feedstock blending and monitoring, diesel/kerosene blending or production, and the quality monitoring of crude at remote collection and storage facilities.

Process sulfur application background

While in-line sulfur gauging - for blending, switching and QC - has been around for years, older technologies never delivered on their promise because those systems did not produce consistent measurements. For the accurate on-line determination of sulphur, the new Rigaku NEX XT resolves those past issues and is thus the perfect tool for blending operations supplying marine bunker fuels and crude feedstock for refineries. With uniquely engineered hardware and novel proprietary software technologies, the new Rigaku NEX XT system is faster, more sensitive and far more compact than previous generation systems and provides continuous, reliable detection of sulfur from 200 parts-per-million (ppm) to 6.0 wt. %, with analysis times as short as 1 second. The Rigaku NEX XT can operate as a stand-alone analyzer or provide real time closed loop control when tied into a blending or plant wide automation system.
