Replace Dangerous Radioisotope Based Sulphur Gauges with NEX XT Process Sulphur Analyser

Applied Rigaku Technologies, Inc. (USA) is pleased to introduce the new Rigaku NEX XT on-line sulfur. This product represents the next generation of process gauge for high-level sulphur 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 (XRT) process gauge is specifically optimized for the sulphur analysis needs of refineries, pipelines, blending operations, bunkering terminals and other storage facilities. Applications include bunker fuel blending to meet MARPOL Annex VI sulphur 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.

The new Rigaku NEX XT system is faster, more sensitive and far more compact than competitive systems and provides continuous, reliable detection of sulphur at pressures up to 1480 psig and 200ºC.

The NEX XT can operate as a stand-alone analyser or provide real time closed loop control when tied into a blending or plant wide automation system. Based on the X-ray Transmission (XRT) measurement technique, the hydrocarbon stream travels through a flow cell where the sample is illuminated using a safe low power X-ray tube. A detector on the opposite side of the flow cell measures transmitted X-rays. Signal intensity is inversely proportional to the sulfur concentration. The system contains no radioisotope sources and requires no routine maintenance.

Among its other key features are a simplified user interface, reduced standards requirement, automatic density compensation, automatic water compensation, password protection, and standard platform for communicating sulfur, density, and water content to a plant-wide DCS. Due to its unique design and robust construction, sample conditioning and recovery systems are typically not required.
