compound is hydrogen sulphide. Depending on the efficiency of the hydrodesulphurisation process other sulphur compounds such as carbon disulphide, carbonyl sulphide, and thiophenes could be present. Tese sulphurs could result in catalyst life being reduced to hours instead of years. Te continuous on-line total sulphur analyser can provide analysis for monitoring catalyst, says ASI.
For its part, Termo Fisher Scientific has launched a new total nitrogen and total sulphur (TN/TS) analyser, which features an innovative direct injection design providing the capacity to analyse both heavy and light hydrocarbons without changing introduction modules.
As a result of the versatility, precision and accuracy offered by the Termo Scientific iPRO
5000 series analyser, scientists in petrochemical and commercial testing laboratories, oil refineries, R&D centres and chemical plants,
will benefit from significant time savings and productivity advantages, in addition to total ASTM compliance (Fig. 1).
Te iPRO 5000 series TN/TS analyser features the proprietary Termo Scientific jetPRO direct spray injector, which enables automatic analysis from ppb levels up to percent levels for both nitrogen and sulphur on just one instrument and without changing introduction modules. As a result, it is now possible to quantify nitrogen and sulphur in heavy hydrocarbons within just three minutes.
Compared with the standard boat method, this is a dramatic reduction in the time spent from analysis to viewing results, which provides an immediate cost-saving and productivity increase.
Offering exceptional precision of two percent or better when analysing light hydrocarbons at ultra-low concentrations, the analyser ensures high accuracy, as well as
reproducibility and repeatability of analysis. Providing meticulously controlled combustion processes, the analyser also contains a proprietary pre-soot detection technology which ensures complete combustion that is soot-free.
Termo Scientific says that the iPRO 5000 series analyser is also the smallest and most compact total nitrogen and total sulphur analyser currently available.
Developed for a wide range of applications, the iPRO 5000 series analyser offers an ideal solution for the diverse requirements of petrochemical analyses.
Te instrument provides the capacity to analyse virtually any refinery sample from raw crude to end product, while ensuring ASTM compliance and enabling optimisation of refinery processes. For commercial testing laboratories requiring ASTM compliant results quickly and cost-effectively over a wide range of applications, the iPRO
5000 series analyser is four times faster than previous methods which enables a significant increase in productivity and cost-efficiency.
In addition, the instrument’s exceptional precision makes it the ideal choice for high performance applications such as those conducted by R&D centres.
Te iPRO 5000 series analyser is controlled by Termo Scientific NSX Visual software, which supports Microsoft Windows 7 and has been developed to adapt to the specific workflows of users who require ease–of-use and flexibility.
Te NSX Visual software assures total ASTM compliance through pre-loaded ASTM method templates, which enable the user to simply select the required method and start the analysis. Te software is also programmed to proactively alert the user if method parameters are changed to a value which is outside the scope of the official ASTM methods.
